Genetic variability and association of component characters for seed yield in Olitorius jute

Abstract: Study indicated that pod length, seeds per pod, seed weight per pod, 100 seed weight and days to 50% flowering were likely to be operated by non-additive gene action in olitorius jute. Correlation study indicated that the seeds of late flowering genotypes have higher volume than the early flowering genotypes. It is also suggested that good pod length is required for more number of seeds per pod as well as high seed weight per pod. From the path-eoefficient analysis it is suggested that a medium flowering genotype with high l00-seed weight, followed by seeds per pod and pod length is most suitable for better seed production in olitorius jute.

Phytochemical investigation of Corchorus olitorius and Corchorus capsularis (Family Tiliaceae) that grow in Egypt

Abstract: Background and objective Corchorus (Family Tiliaceae) is a genus of annual herbs. Nearly 40 species are known to occur in nature and distributed in the tropics of both hemispheres. Because of the wide medicinal applications of compounds isolated thereof, the present investigation deals with the isolation and structure elucidation of some phytochemicals from Corchorus olitorius (molokheya) and Corchorus capsularis that grow in Egypt. Materials and methods Phytochemical investigation of the seeds and different plant organs of both C. olitorius and C. capsularis was achieved applying different separation techniques. Petroleum ether extraction followed by saponification of the extract led to the isolation of phytosterols, hydrocarbons and fatty acids. Essential oils were obtained from the leaves by extraction with methylene chloride. Methanolic extraction led to the isolation of cardiac glycosides. Identification of isolated compounds was realized through Rf values, shift reagents and spectroscopic tools such as ultraviolet and nuclear magnetic resonance. The fatty acids were identified using gas liquid chromatography. Results and conclusion A study of the lipid contents (fatty acids, phytosterols and hydrocarbon components) of seeds, roots, leaves and stems of C. olitorius as well as the seeds and vegetative part of C. capsularis, which grow locally in Egypt, was carried out. The identification of the lipid content was achieved by comparing the retention time of their peaks in gas liquid chromatography with those of authentic samples. Gas chromatography/mass spectrometry study of the chemical constituents of the essential oils of the leaves of C. olitorius and C. capsularis led to the identification of 11 and 21 compounds with a total concentration of 24.7 and 62.9%, respectively. Cedrane-5-one (17.7%) and γ-terpinene (12.1%) represent the major compounds in each plant, respectively. Phytochemical investigation of C. olitorius led to the isolation of raffinose I, coroloside II, glucoevatromonoside III, erysimoside IV and olitoriside V and gluco-olitoriside VI. Meanwhile, the study of the vegetative parts of C. capsularis led to the isolation of 3-O-glucopyranosyl-β-sitosterol VII. The isolated compounds were identified by spectral tools (hydrogen-1, carbon-13-nuclear magnetic resonance, electron ionization mass spectrometer).

Microflora diversity on the phyloplane of wild Okra ( Corchorus olitorius L. Jute )

Abstract: Indigenous people especially in southern Nigeria use Corchorus olitorius L . (Jute) as a staple vegetable. Population dynamics, richness and frequency of occurrence of microflora isolates on healthy green leaves of wild okra were estimated within two weeks at weekly intervals using the dilution technique. This study was conducted in the University of Benin intend to show the diversity of microorganisms on the leaves of wild okra. The leaves were categorized based on their period of harvest into old, new and middle with a week interval between each harvest. After serial dilution in distilled water, isolation was done using nutrient agar for bacteria and potato dextrose agar for fungi. After incubation colony forming units per millimeter were counted, isolated, identified and characterized using standard microbiological techniques. The fungal diversity and frequency of occurrence were higher in the first sampling (61.50% and 62.07% respectively) than those of the second sampling (38.50% and 37.93%). Total viable microbial population in the second sampling after two weeks was higher (11.23 X 102cfu/ml) than in the first sampling after one week (10.00 X 102cfu/ml). The total cumulative bacterial count was higher (15.69X 102cfu/ml) than those of fungi (55.40 X 102 cfu/ml) during the studies. Bacterial genera isolated included; Staphylococcus, Bacillus, Micrococcus, Serratia and Proteus . Rhodotorula, Mucor, Trichoderma, Aspergillus, Penicillium, and Helminthosporium were the genera of fungi isolated. Further studies could help to elucidate major players in wild okra phylloplane ecology. Keywords : Wild Okra ( Corchorus olitorius ), Phylloplane, Microflora population, Bacteria, Fungi
