Descriptors for jute (Corchorus olitorius L.)

Abstract: Detailed information about genetic differences among individuals or groups of accessions can be helpful for management and utilization of germplasm collections. So, descriptor assist scientists to improve their capacity to describe, store, manage and share information about plant resources, whether stored in genebanks or growing in natural environments. It is also an important tool to enable information sharing for crops, facilitate the international exchange and use of plant resources, uniformity in data description. Provide an international format and a universally understood language for plant genetic resources data. They are targeted at farmers, curators, breeders and users and facilitate the exchange and use of resources (Rana et al. 1991, Van Hintum in Genet Resour Crop Evol 40:133–136, 1993). This test guideline was developed to apply to all varieties of C. olitorius and C. capsularis. It is an important tool to enable gathering and sharing information about the two cultivated species, C. olitorius and C. capsularis biodiversity. C. olitorius and C. capsularis, are tall, usually annual herbs, reaching a height of 2.4 m. They are used as a major source of natural fibres mainly in Asian and Latin American countries. C. olitorius (jute mallow) is an important green leafy vegetable in many areas. Different parts of C. olitorius are also used in folk medicine (Patel and Datta in Grana Palynol 1:18–24, 1958; Rao in Sydowia 30:164–185, 1977; Sajib et al. in Plant Cell Tissue Organ Cult 95:333–340, 2008).

Confamiliar transferability of simple sequence repeat (SSR) markers from cotton ( Gossypium hirsutum L.) and jute ( Corchorus olitorius L.) to twenty two Malvaceous species

Abstract: Cross-species transferability is a quick and economic method to enrich SSR database, particularly for minor crops where little genomic information is available. However, transferability of SSR markers varies greatly between species, genera and families of plant species. We assessed confamiliar transferability of SSR markers from cotton (Gossypium hirsutum) and jute (Corchorus olitorius) to 22 species distributed in different taxonomic groups of Malvaceae. All the species selected were potential industrial crop species having little or no genomic resources or SSR database. Of the 14 cotton SSR loci tested, 13 (92.86 %) amplified in G. arboreum and 71.43 % exhibited cross-genera transferability. Nine out of 11 jute SSRs (81.81 %) showed cross-transferability across genera. SSRs from both the species exhibited high polymorphism and resolving power in other species. The correlation between transferability of cotton and jute SSRs were highly significant (r = 0.813). The difference in transferability among species was also significant for both the marker groups. High transferability was observed at genus, tribe and subfamily level. At tribe level, transferability of jute SSRs (41.04 %) was higher than that of cotton SSRs (33.74 %). The tribe Byttnerieae exhibited highest SSR transferability (48.7 %). The high level of cross-genera transferability (>50 %) in ten species of Malvaceae, where no SSR resource is available, calls for large scale transferability testing from the enriched SSR databases of cotton and jute.

Effect of Citric Acid on Cadmium Ion Uptake and Stress Response of Hydroponically Grown Jute Mallow ( Corchorus olitorius )

Abstract: This research work investigates the possibility of improving the phytoextraction of Cd by the application of citric acid. For this purpose, plants were grown in hydroponics under controlled conditions. Addition of 1, 5, 10 and 20 mg/L, Cd2+ significantly decreased the plant growth and biomass, and increased proline contents. The effects were dose dependent with obvious effects at higher Cd2+ concentration of 20 mg/L. Application of 5mM citric acid (CA) significantly depressed Cd2+ uptake and its accumulation in plant roots and shoots. CA alleviated Cd2+ toxicity by reducing oxidative stress. Application of CA also enhanced the antioxidant enzymes activity alone and under Cd stress. The results showed that Cd2+ accumulated more in roots than the shoots and application of citric acid depressed Cd2+ uptake at all concentrations. Jute mallow (Corchorus olitorius) proved to be an effective accumulator for cadmium, however, neither concentration of citric acid showed advantages for phytoextraction of cadmium. The results showed that jute mallow is a potential plant for phytoextraction of Cd without the use of CA as enhancer.

The role of corchorus in spreading of tomato yellow leaf curl virus on tomato in Jeddah, Saudi Arabia.

Abstract: Corchorus (Corchorus capsularis L. and Corchorus olitorius L.) is one of the most important fiber crops grown in tropical and subtropical regions throughout the world. Field survey was conducted and naturally infected leaf samples were collected from corchorus and tomato plants in Jeddah, Saudi Arabia. The causal virus was transmitted by whiteflies to tomato plants and begomovirus infection was confirmed by Polymerase chain reaction. The complete viral genome and associated betasatellites were amplified, cloned and sequenced from both corchorus and tomato samples. The genetic variability and phylogenetic relationships were determined for both isolates (corchorus and tomato). The complete genome sequences showed highest (99.5 % nt) similarity with tomato yellow leaf curl virus (TYLCV) and formed closest cluster with TYLCV-Tomato reported from Jizan and Al-Qasim, Saudi Arabia and betasatellites sequences showed highest similarity (99.8 % nt) with Tomato yellow leaf curl betasatellites-Jeddah followed by Tomato yellow leaf curl Oman betasatellites and formed closed cluster with TYLCV-Tomato. On the basis of results obtained from whiteflies transmission, sequence similarity and phylogenetic relationships; it is concluded that the identified virus could be a variant of TYLCV circulating in the Kingdom. The significance of this study demonstrated that the corchorus is serving as reservoir and alternative host and playing an important role in spreading the begomovirus associated disease in the Kingdom of Saudi Arabia.

Yield and quality of Corchorus olitorius baby leaf grown in a floating system

Abstract: Corchorus olitorius is mainly cultivated in Africa and is used in the human diet for its nutraceutical proprieties. In this work, C. olitorius was grown in a floating system using a standard (NS100%) or halved (NS50%) nutrient solution. Yield was evaluated at harvest when plants reached the baby leaf stage. Quality of leaves was estimated by measuring sugars, nitrate, chlorophylls, carotenoids, polyphenols, and anthocyanins. Yield was similar to other common leafy vegetables cultivated in floating systems. Analytical determinations showed good levels of antioxidant compounds and sugars. Mineral contents were relevant for Ca, Mg and Fe in comparison with C. olitorius cultivated in soil and other common leafy vegetables. Results showed these plants had healthy characteristics for human nutrition, in particular for women and children. C. olitorius had a good performance in the floating system with yield ranging from 0.8 to 2.4 kg m−2. Mineral nutrient levels were higher than in the major leafy vegeta...

Corchorus Olitorius Linn: A Rich Source of Ω3-Fatty Acids.

Abstract: Fatty acids composition of Corchorus olitorius Linn were identified as their methyl esters using accurate mass gas chromatography quadrupole time of flight mass spectrometry (GCQTOF) in chemical ionization (CI) and electron ionization (EI) modes. The leaves which are the edible part of the plant were found to be very rich in ω3- octadecatriene fatty acid reaching up to more than 49 % of the total fatty acids contents. This is the first report to unequivocally detect ω-3 fatty acid in Corchorus olitorius Linn with a much higher concentration than any other reported vegetable and further investigation into its health effects are clearly warranted.

Study of arsenic accumulation in rice and evaluation of protective effects of Chorchorus olitorius leaves against arsenic contaminated rice induced toxicities in Wistar albino rats

Abstract: In the present study, we investigated the arsenic accumulation in different parts of rice irrigated with arsenic contaminated water. Besides, we also evaluated the protective effects of Corchorus olitorius leaves against arsenic contaminated rice induced toxicities in animal model. A pot experiment was conducted with arsenic amended irrigation water (0.0, 25.0, 50.0 and 75.0 mg/L As) to investigate the arsenic accumulation in different parts of rice. In order to evaluate the protective effects of Corchorus olitorius leaves, twenty Wistar albino rats were divided into four different groups. The control group (Group-I) was supplied with normal laboratory pellets while groups II, III, and IV received normal laboratory pellets supplemented with arsenic contaminated rice, C. olitorius leaf powder (4 %), arsenic contaminated rice plus C. olitorius leaf powder (4 %) respectively. Different haematological parameters and serum indices were analyzed to evaluate the protective effects of Corchorus olitorius leaves against arsenic intoxication. To gather more supportive evidences of Corchorus olitorius potentiality against arsenic intoxication, histopathological analysis of liver, kidney, spleen and heart tissues was also performed. From the pot experiment, we have found a significant (p ≤ 0.05) increase of arsenic accumulation in different parts of rice with the increase of arsenic concentrations in irrigation water and the trend of accumulation was found as root > straw > husk > grain. Another part of the experiment revealed that supplementation of C. olitorius leaves with arsenic contaminated rice significantly (p < 0.05) restored the altered haematological parameters and other serum indices towards the normal values. Arsenic deposition pattern on different organs and histological studies on the ultrastructural changes of liver, kidneys, spleen and heart also supported the protective roles of Corchorus olitorius leaves against arsenic contaminated rice induced toxicities. Arsenic accumulation in different parts of rice increased dose-dependently. Hence, for irrigation purpose arsenic contaminated water cannot be used. Furthermore, arsenic contaminated rice induced several toxicities in animal model, most of which could be minimized with the food supplementation of Corchorus olitorius leaves. Therefore, Corchorus olitorius can be used as a potential food supplement to the affected people of arsenic prone zone to ensure the food security.

Identification and expression profiling of microRNAs and their corresponding targets related to phytoremediation of heavy metals in jute (Corchorus olitorius var. O-9897)

Abstract: A cost effective plant-based approach for the remediation of contaminated soil and water that pose a major environmental and human health problem, is termed phytoremediation. It takes advantage of the remarkable ability of plants to concentrate heavy metals and polluted compounds from the environment and to metabolize the same in their tissues. Industrialization and irrigation with heavy metal (i.e. As) polluted water is a source of contamination of the surface environment in Bangladesh. In the present study, a microRNA (miR319) and a gene (ATP-binding cassette transporter/ABC), known to be involved in heavy metal stress tolerance were identified in jute. Moreover profiling of heavy metal responsive microRNAs (miR159 and miR167) and their target genes (ABC and auxin responsive factor 8/ARF8) under three heavy metal stressors (As, Mn and Cr) indicated jute to be an accumulator of manganese (Mn) and chromium (Cr) but not arsenic (As). Furthermore, the experimental results suggest that down-regulation of jute-miR159 and jute-miR167 may confer better heavy metal tolerance in jute.

Phytochemical Investigation of Antimicrobial and Antioxidant Activity Leaves Extracts of Corchorus olitorius

Abstract: The leaves extracts of Corchorus olitorius, the family Malvaceae, are commonly called khudra, the plant extensively used in Sudanese traditional medicine. The Sudanese varieties are one of the best in the market, which prompted investigation of leaves extracts. Some chemical analyses of the leaves have been done such as determination of ash content and trace elements (Ca, Fe, Mg, and Na) by atomic absorption spectrometry. The 96% ethanolic, Ethyl acetate and chloroform extracts exhibited significant antimicrobial activity and highlighted the biological monitoring of activity in order to isolate the active metabolites from the ethanolic extract of the leaves. The presence of sterols and triterpenes, carotenoids, coumarins, alkaloids, saponins, tannins, flavonoid and carbohydrates was confirmed by phytochemical screening of the diethyl ether, methanolic and aqueous extracts of the leaves. The extracts were screened in different solvent systems by thin layer chromatography. The methanolic, Ethyl acetate extract exhibited significant antioxidant activity. From the above-mentioned extract we prepare cream and ointment as antibacterial and antifungal dosage forms.

Variation of morphological and chemical properties of three varieties of jute stick.

Abstract: Pulp property of a lignocellulosic material depends upon its morphological characteristics and chemical constituents it. Shabuj Pat (CVL-1) variety from Corchorus capsularis and BJRI Tossa Pat 4 (O-72) and BJRI Tossa Pat 5 (O-795) varieties from Corchorus olitorius of jute are mostly grown in Bangladesh. This study deals on morphological and chemical properties of these three varieties of jute stick to assess their suitability for pulp production. The results were significantly differed among the varieties and within the variety. The α-cellulose content was almost the same in the variety of CVL-1 and O-795. In the same variety, the middle portion contained the largest amount of alpha-cellulose and the top portion contained the lowest. Klason lignin content varied from 24.2 to 26.8%. Fibre length was significantly same for all the three jute sticks but the width and slenderness ratios were different. Pulp yield in soda anthraquinone process was nearly the same in all these varieties around 44% at kappa number 15. Bangladesh J. Sci. Ind. Res. 51(4) , 307-312, 2016

Rhizosphere and non-rhizosphere soil mycoflora of corchorus olitorius (jute)

Abstract: The physicochemical and microbial analyses of the rhizosphere and non-rhizosphere soils of Corchorus olitorius (Jute) were conducted. The soil samples were analyzed before planting of Jute seeds and the average values of the parameters were 11.24% (percentage moisture content), 0.29ml/g (water holding capacity), 1.36% (organic matter content) and 6.80 (soil pH). The textural class of the soil sample is sandy. Aspergillus niger and Rhizopus stolonifer occurred most followed by Aspergillus flavus , while Penicillium chrysogenum , Saccharomyces cerevisiae and Neurospora crazza occurred least in the rhizosphere and non – rhizosphere soil samples of Jute in this study. Occurrence of these fungi in both the rhizosphere and non-rhizosphere soils varied widely throughout the duration of this study. It can be concluded that the jute plants benefitted from the microorganisms (fungi) in their rhizosphere and non – rhizosphere zones since the plants showed healthy growth. Keywords: Corchorus olitorius , Fungi, Non–rhizosphere soil, Rhizosphere soil, physicochemical

A study on controlling Setaria viridis and Corchorus olitorius associated with Phaseolus vulgaris growth using natural extracts of Chenopodium album

Abstract: The effects of water extracts of Chenopodium album leaves and roots on the growth of grass weed (Setaria viridis) and broad leaf weed (Corchorus olitorius) grown with beans (Phaseolus vulgaris) in greenhouse pots were studied in the National Research Centre, Giza, Egypt. In this experiment fresh leaf and root extracts and their corresponding dry leaf and root extracts at different concentrations were used. There were significant inhibitions in the dry weights of S. viridis and C. olitorius by all extracts at the flowering stage of beans and at harvest. The inhibition effect of all C. album extracts on both weeds (dry weight/pot) depended on the extracted plant organ (leaf or root), its fresh or dry form as well as its concentrations. The inhibition caused by the leaf extract was much higher on weed growth than that of root extract. A higher concentration of fresh leaf extract (25%) had the highest significant inhibition effect. The results also indicated that C. olitorius was more sensitive to the extracts than S. viridis. On the other hand, the inhibition effect of the extracts on the growth of both weeds was accompanied by increased bean growth and yield/plant. The analysis of both leaf and root extracts of C. album revealed that the total content of polyphenols and flavonoids in the leaf extract was more than triple that of the root extract. The results suggested that the fresh leaf extract of C. album may be a possible tool for the development of weed control using natural herbicides.

Phytochemical and Antifungal Activity of Leaf Extracts of Corchorus olitorius and Gongronema latifolium on Fungi Associated with Post-Harvest Deterioration of Maize (Zea mays) Seeds in Oban Community, Nigeria

Abstract: This study was carried out to investigate the fungal pathogens associated with post-harvest deterioration of maize seeds in storage in Oban community, Cross River State, Nigeria, determine the effect of the pathogens on the nutritional content of the maize seeds through biochemical analysis as well as evaluate the phytochemical contents and antifungal activity of ethanolic leaf extracts of Corchorus olitorius and Gongronema latifolium in controlling the isolated fungi in vitro. The fungal pathogens isolated as the causative agents of post-harvest deterioration of maize seeds in this study were Penicillium sp., Fusarium sp., Aspergillus sp., and Rhizopus stolonifer. The result of biochemical analysis of fungal infected and non-infected maize seeds carried out showed a significant increase (P ≤ 0.05) in the moisture content of the fungal infected maize seeds as compared to healthy ones (control), while there was a significant decrease (P ≤ 0.05) in the crude fibre, fat, ash, protein and carbohydrate contents of the fungal infected maize seeds as compared to the healthy ones (control). For the in vitro antifungal assay, various concentrations of the extracts ranging from 20g/200ml, 40g/200 ml, 60g/200 ml, 80g/200 ml and 100g/200 ml were separately added to PDA media. Results shows that at 60g/200 ml and 80g/200 ml and 100g/200 ml concentrations, ethanolic leaf extracts of C. olitorius completely inhibited the radial growth of Penicillium sp., Fusarium sp., Aspergillus sp., and R. stolonifer after seven days observation period while those of ethanolic extracts of G. latifolium completely inhibited the redial growth of the fungal pathogens at 40g/200 ml, 60g/200 ml, 80g/200 ml and 100g/200 ml concentrations. Results, however, shows that the extracts had a significant effect (P ≤ 0.05) on the World Scientific News 53(3) (2016) 157-177 -158radial growth of the fungal pathogens at all the different concentrations tested as compared with the control. Phytochemical screening of the extracts revealed the presence of cardiac glycosides, reducing sugars, flavonoids, saponnins, tannins, hydocyanin, and anthraquinones with traces of alkaloids.

Physiological and Agromorphological Responses of Tossa Jute (Corchorus olitorius L.) to Drought Stress

Abstract: The effect of water deficit on physiological and agro-morphological parameters related to water deficit tolerance was studied in Tossa Jute (Corchorus olitorius L.), from Tunisian oasis. The experiments were carried at the Arid and Oases Cropping Laboratory, Institute of Arid Lands (IRA), Tunisia. Seeds were allowed to germinate in pots filled with sand and peat at a 2:1 ratio, respectively. After 1 month, the plants were subjected to 3 water treatments: control irrigation (R1: 100% of field capacity, FC), moderate water deficit (R2: 70% FC), and severe water deficit (R3: 40% FC). At 4 weeks of stress, the plants were harvested and subjected to some agrophysiological and biochemical analyses related to tolerance. The effect of different treatments on all studied traits was significantly important. Whole growth and leaves traits and reproductive traits were more significantly affected by 40% FC than the 70% FC and control. In addition, the water limitation for 40% (R1) and 70% (R2) of field capacities caused severe reduction of dry weight of aerial part by 50.6 and 79.4 % respectively and relative water content (RWC) of 20.99 and 53.35% respectively compared to controls plants. The net photosynthetic, the transpiration rates and the contents of chlorophyll significantly decreased in plants subjected to water deficit. Plants submitted to 40% FC accumulated higher concentrations of proline (2.07 mg/g DW) and soluble sugars (12.68 μg/g FW) than the controls ones. Tossa jute seedlings make different strategies to tolerate the water deficit by increasing the osmo-regulators contents, developing roots and reducing leaves size.

Evaluation of Jute Leaf as Feed Ingredient for Labeo rohita Fingerlings

Abstract: A 60 day feeding trial was conducted to evaluate the suitability of jute (Corchorus olitorius) leaf powder, as a dietary protein source for Labeo rohita fingerlings. One control feed without jute leaf JL0 (0%) and four experimental feeds were prepared with graded levels of jute leaf powder viz; JL10 (10%), JL20 (20%), JL30 (30%) and JL40 (40%) respectively along with rice bran, soybean meal, mustard oil cake, vegetable oil and vitamin-mineral mixture. The feed with 20% of jute leaves (JL20) showed significantly (P<0.05) higher net weight gain, specific growth rate, protein efficiency ratio and daily growth coefficient. The feed conversion ratio was lower (P<0.05) in JL20. The carcass composition revealed that carcass protein and lipid content was significantly (P<0.05) higher in JL20. It may be concluded that jute leaf powder can be incorporated in the feed of rohu fingerlings up to 20%.

Determination of Water Use of Three Vegetables; Amaranthus ( Amaranthus cruenthus ), Jutemallo ( Corchorus olitorius ) and Celosia ( Celosia argentea ) at Abeokuta, Nigeria

Abstract: An experiment was carried out at the screen house of the college of environmental resources management at the Federal University of Agriculture Abeokuta, Ogun state to determine water use of three vegetable: Amaranthus, Corchorus and Celosia. The experiment was laid out in a completely randomized design (CRD) and was replicated three times with a control. 50 cl of water was applied to the crops at a day interval. Data collected were analyzed making use of ANOVA and statistical analysis system was used to compare the means of the crops planted as a sole of each crop planted and the test was also used to formulate two hypotheses. The result showed that there were no significant differences between the water uses of each vegetable while there were significant differences between the crop coefficients of each vegetable. Based on the experiment carried out, it was observed that the celosia, amaranthus and corchorus needed the same amount of water for their growth. Therefore it is recommended that farmers that practice rainfed agriculture during dry season when there will be or no rain make sure that sufficient water is been supply to the three vegetable crops for rapid growth and optimum yield

Combining Ability and Heterosis Study for Fibre Yield and Yield Attributing Characters in Tossa Jute (Corchorus olitorius L)

Abstract: Combining Ability and Heterosis Study for Fibre Yield and Yield Attributing Characters in Tossa Jute (Corchorus olitorius L) Present study was carried out to estimate combining ability and heterosis for fibre yield and yield attributing characters among diverse tossa jute germplasm lines and in 21 F1 hybrids derived from 7 x 7 half diallel mating design. Analysis of variance revealed significance of parent’s vs hybrids for most of the characters indicating presence of heterosis. High gca effects for fibre yield, plant height and green weight was recorded by OIN-255. High significant sca effects for fibre yield were recorded in OMU-19 x OMU-27 (19.53**) and OIN-255 x OEX-32 (15.50* ) crosses. Variances for general combining ability and specific combining ability were significant for few characters indicating additive and non-additive gene actions for those characters. High standard heterosis for fibre yield was recorded by OMU-19 x OMU-27 (41.01**) and OIN-255 x OEX-32 (32.47* ) crosses. Genetic parameters indicated that plant height, green weight and stick weight were controlled by additive gene action and basal diameter and fibre yield controlled by nonadditive gene action.

Effect of soil amendments on yield of wild okra (Corchorus olitorius) in northern KwaZulu-Natal, South Africa

Abstract: The consumption of semi-domesticated indigenous vegetables such as Corchorus olitorius is being promoted in South Africa. Presently, cultivation of indigenous vegetables is hampered by the absence of cultivation guidelines due to lack of agronomic research on the various production aspects. The current study evaluated the yield of C. olitorius in response to cattle manure (5 000 kg ha−1) and NPK inorganic fertiliser (500 kg ha−1). Plant height, number of branches, marketable fresh yield and shoot dry mass responded significantly (p<0.05) to the applied fertilisers. Growing Corchorus without basal fertiliser gave significantly the lowest yield even when top-dressing nitrogen fertiliser was applied. There were significant interactions between the different basal and nitrogen top-dressing fertiliser. It was concluded that the application of basal soil amendments and the interaction of basal and top-dressing resulted in increased marketable yield for C. olitorius. The highest marketable yield for both cattle manure and NPK fertiliser were obtained when these were combined with 200 kg ha−1 lime ammonium nitrate.

Influence of Corchorus Olitorius (Molokhia) Soup on the In Vivo Absorption of Ciprofloxacin from Immediate Release Tablet in Rabbits

Abstract: This study was undertaken to evaluate the effect of Corchorus Olitorius (Molokhia) soup on the oral absorption of ciprofloxacin from solid dosage forms in rabbits. A single dose of ciprofloxacin tablet (125 mg) was administered to rabbits in a fasted state or with Molokhia soup. Plasma ciprofloxacin concentrations were measured by high-performance liquid chromatography. The results demonstrated a profound effect of Molokhia soup on the bioavailability of ciprofloxacin compared to the fasted state. The intake of Molokhia soup reduced the rate and extent of ciprofloxacin oral bioavailability. The geometric mean (Cmax and AUC) values of ciprofloxacin were significantly lower under fed compared to the fasted states. Administration of ciprofloxacin with Molokhia soup was associated with a delay in the time to reach peak concentration (Tmax) by about half hour. Therefore, co-administration of Molokhia soup with ciprofloxacin may have a potential negative effect on the release and oral absorption of Ciprofloxacin from tablets, This may result in serious decrease in the efficacy of this antibiotic and potential bacterial resistance.

Effect of Cooking on Nutritive Value of Jew’s Mallow (Corchorus olitorius L.) and Mallow (Malva parviflora L.) Leaves

Abstract: The impact of cooking by boiling on nutritive value of Jew’s mallow (Corchorus olitorius L.) and mallow (Malva parviflora L.) leaves were assessed by determining the proximate chemical composition, some minerals, amino acids and dietary fiber fractions. The results indicated that the raw and cooked leaves of Jew’s mallow and mallow (on dry weight basis) contained high crude protein in a range of (36.73-44.77%), crude fibers (9.81-12.73%) and total ash content (9.30-16.85%), but low in crude fat (1.05-3.39%). The energy values ranged between 259.7 and 285.29 k cal/100g. The raw and cooked leaves had high content of total dietary fiber (32.74-41.45%), insoluble dietary fiber (26.10-32.51%), soluble dietary fiber (6.64-8.94%). The neutral detergent fiber were in range of (20.94 to 28.98%), acid detergent fiber (16.97-25.61%) and acid detergent lignin (7.00-8.93%). The sample contained high potassium content (856-1020 mg/100g) followed by calcium (216.5-412.5mg/100g) and magnesium (170-206 mg/100g) and low content of iron (4.68-5.31mg/100g). Cooking of Jew’s mallow and mallow leaves significantly (P≤ 0.05) increased the crude fiber, non reducing sugars, soluble dietary fiber, acid detergent fiber, cellulose, phosphorus and sodium. Whereas, significantly (P≤ 0.05) decreased the reducing sugars, hemicelluloses, calcium and magnesium. All samples contained adequate amounts of the essential and non essential amino acids except that of methionine, which was considered as the first limiting amino acid, followed by leucine and phenylalanine. Both of the cooked leaves can be suggested to act as a functional food.

Agromorphological evaluation of accessions of jute potager (Corchorus olitorius. L) of Burkina Faso

Abstract: Forty-one (41) accessions of the jute potager (Corchorus olitorius L.) collected in Burkina Faso were evaluated on July 2014 with twenty-five (25) characters according to a Latinized Apha-Plan. The global objective of this study is to contribute to a better knowledge of the agromorphological diversity of C olitorus of Burkina Faso. The study revealed that 75,61% of the accessions studied belong to C olitorius var olitoriu L. variety and 24,39% belong to C olitorius var incisifolius Asch.and Schw variety. It showed indeed that several characters discriminate the accessions at 1%. The study of the structuring of diversity revealed three groups of accessions on the basis of the plant height, stem diameter, width of leaf and leafy biomass. Thus, the group I is constituted of big size accessions with robust stem, high leafy biomass and thin fruits. The Group II is constituted of individuals with performances relatively low. The Group III is a mixed group constituted with 65% C olitorius var clitoris L. and 35% of C olitorius var incisifolius Asch. and Schw. This group is made up of individuals with reduced size, with weak leafy and big fruits.

Assessment of genetic diversity in Jute (Corchorus olitorius L.) under rain fed condition

Abstract: Jute fibre is obtained from the bark of the two commercially important species namely Corchorus capsularis L. and Corchorus olitorius L. 20 genotypes of white jute were sown in Randomized Block Design with three replications classified by Mahalanobis D 2 statistics under rainfed condition to identify desirable genotypes for use in breeding programme to develop drought tolerant hybrids. Maximum inter cluster distance was observed between cluster III and II while cluster III showed the maximum intra cluster distance. Green weight was found to be the maximum contributor (21.58%) towards divergence followed by dry stick weight (20%), top diameter (15.79%) and fibre yield (14.74%). Cluster V was found to be most important group for a number of characters like green weight, bark thickness, basal diameter as well as mid diameter, plant height and internode length. Therefore, for improvement of the crop the genotypes from clusters V, IV and II may be considered to obtain high fibre yielding lines with characteristic features like earliness and plant with least number of nodes under rainfed condition. Key words: Tossa jute, fibre, rainfed, divergence, olitorius.

Stability of fibre yield and its component traits in tossa jute (Corchorus olitorius L.)

Abstract: Stability study for fibre yield and its attributing traits was carried out in six tossa jute ( Corchorus olitorius L.) genotypes including two checks under four different ecological conditions of India over two consecutive years 2005 and 2006, I under All India Network Project on Jute and Allied Fibres. Six experimental entries in AVT-I and AVT-II responded differentially to the different environments as evidenced by their non significant difference for the different traits in the different environments. On the basis of the stability parameters Wi (Wricke’s Ecovalence) and Di (Hanson’s genotypic stability) the genotype JRO-524 (standard check) was identified as stable for fibre yield and its attributing traits over the environments. It was followed by the genotype CO-56 with high fibre yield and moderate Wi (%) and Di values. These two genotypes were identified to be suitable for high input conditions of cultivation.

Ephedran prepared through steam explosion method and use thereof

Abstract: The invention belongs to a solid adsorbent and a preparation method thereof and relates to an adsorption material with ephedran as a main component and a preparation method thereof. Corchorus olitorius leaves and young shoots have excellent effects of removing hexavalent chromium in water because histocyte is rich in polyose substances such as pectin, -OH and -NH2 groups of polyose are typical basic groups and the special structures have chelation effects on metal ions with a certain ion radius at a certain pH value so that the polyose substances are natural metal chelate agents. Corchorus olitorius leaves and young shoots are used as raw materials and a large amount of polyose substances such as pectin are separated through physical and chemical processes. The separated substance has good adsorption effects, can be processed simply, has a low cost, easily realizes commercialization and improves added value of corchorus olitorius as the traditional fiber crop.

Supercritical extraction method for jute polysaccharide and application of jute polysaccharide

Abstract: The invention belongs to solid adsorbents and preparing methods thereof and particularly relates to an adsorbing material with jute polysaccharide as a main ingredient and a preparing method of the adsorbing material. Leaves and tender shoots of jute have excellent performance on removing hexavalent chromium in a water body, tissue cells contain rich pectin and other polysaccharide substances, and groups such as -OH and -NH2 in the polysaccharide are typical basic groups, so that by means of the special structure, the polysaccharide has chelate action on metal ions with certain ion radiuses under certain PH value conditions, and the polysaccharide is a natural metal chelator. According to the adsorbing material and the preparing method thereof, the leaves and the tender shoots of corchorus olitorius serve as raw materials, rich pectin and other polysaccharide substances in the leaves and the tender shoots are separated out through physical and chemical means, obtained substances are good in adsorbing effect, operation is easy, cost is low, commercialization is easy to achieve, and the additional value of jute as a traditional fiber crop is increased.
