Root Anatomical Responses to Waterlogging at Seedling Stage of Three Cordage Fiber Crops

Abstract: Waterlogging tolerance of tropical cordage fiber crops is an important agricultural subject in northeast Thailand, because they are often grown in dry-wet transition period as pre-rice crops. Since root anatomical characteristics are often considered to be important traits determining waterlogging tolerance of plants, we examined root anatomy of three fiber crops that are different in waterlogging tolerance one another. Seedlings of three cordage fiber crops, Hibiscus cannabinus (kenaf, cv. KhonKaen60), Hibiscus sabdariffa (roselle, Thai kenaf, cv. NonSoong2) and Corchorus olitorius (jute, cv. KhonKaen1), were grown in tall beakers of 1000 ml vermiculite with 40% v/v (control) and 80% v/v (waterlogging) water contents. It is known that the H. cannabinus cultivar is tolerant to waterlogging while other two species (C. olitorius, H. sabdariffa) cultivars are sensitive to waterlogging from soil-grown pot experiments in northeast Thailand. Ten days after sowing, freehand cross-sections of taproot (i.e., prima...

Leaf and seed yield of jute mallow (Corchorus olitorius L.) accessions under field conditions for two consecutive growing seasons

Abstract: Jute mallow is a nutritious leafy vegetable used by many people in Africa. The purpose of this study was to select accessions with high leaf yield and seed yield. We investigated seven agronomic traits that are related to leaf yield and seed yield and how they correlate with each other. The results indicated significant differences among the accessions in all traits. Leaf fresh weight ranged from 18.3 to 121.3 g/plant in accessions TOT 6747 and TOT 8532, respectively. The highest variability between the accessions was also observed in seed yield. It ranged from 1.0 g/plant in accession TOT 7980 to 35.5 g/plant in TOT 7866. Eight other accessions had a seed yield of 1.0 g/plant. Significant and positive correlations were observed between leaf fresh weight and leaf dry weight (r = 0.84), leaf area (r = 0.33), and number of leaves (r = 0.40). A significant correlation was observed in seed yield and weight of pods per plant (r = 0.83). The evaluation of these agronomic traits for leaf and seed yield i...

Influence of Plant Leaf Locations on the Bioaccumulations of Phytotoxins and Nutrients in Corchorus olitorius at Market Maturity

Abstract: Experiment was performed in a pot to examined the effect of leaf locations on the concentrations of some plant toxins (cyanide, nitrate, soluble and total oxalates), and nutrients viz; beta-carotene (provitamin A), vitamin C and mineral elements (Fe, Mg, Cu, Zn, Ca Na and K) at market maturity (vegetative phase) of Corchorus olitorius grown in nitrogen and non – nitrogen treated soil. The leaves of Corchorus olitorius were harvested at three different leaf locations (basal, middle and upper positions) and they were subjected to chemical analysis. The result showed that there was no significant differences in the cyanine concentration between basal and middle leaves, however, the leaves obtained from upper leaf location was significantly (p < 0.05) lower in cyanide concentration than those leaves obtained each from basal and middle leaf regions in control and nitrogen treated Corchorus olitorius . The nitrate content in Corchorus olitorius was significantly (p < 0.05) highest in the basal leaves closely followed by middle leaves and least in the upper leaves in control, however, with the application of nitrogen fertilizer, no significant variation in the nitrate concentration was observed between leaves obtained from middle and upper leaf locations, but leaves obtained from each of these locations were significantly (p < 0.05) lower than those from basal leaf region. Both soluble and total oxalate concentrations increased with leaf age in Corchorus olitorius irrespective of soil nitrogen levels. The concentration of beta-carotene was significantly (p < 0.05) higher in middle leaves compared to basal and upper leaves each in nitrogen and non-nitrogen fertilized Corchorus olitorius . While the concentration of vitamin C was significantly highest in middle leaves followed by upper leaves and least in the basal leaves of Corchorus olitorius irrespective of soil nitrogen levels. The Fe, Cu and Ca contents were generally concentrated in basal and middle leaves of the vegetable. Leaf location had no significant enfluence on the accumulation of Na and Mg in Corchorus olitorius , except that the concentration of Mg in basal and middle leaves was significantly elevated than upper leaves with the application of nitrogen fertilizer. While the concentration of K in Corchorus olitorius was significantly (p < 0.05) elevated in upper and middle leaves compared basal leaves, the concentration of Zn was significantly (p < 0.05) higher in the middle leaves than those obtained each from basal and upper leaf locations. The result concludes that the concentrations of phytoxins (cyanide, nitrate, soluble and total oxalates) are elevated in older leaves than younger ones of Corchorus olitorius .Thus avoiding the consumption of older leaves of the vegetables will reduced the health problems associated with high intake of these plant toxins.

Breeding for nutritional quality for Corchorus olitorius, Annona muricata and Pentaclethra macrophylla 1: A study of their antinutritional contents

Abstract: Breeding for nutritional quality of food/feed crops had somewhat been neglected by plant breeders all through the years. The objectives had mainly been focused on disease resistance and yield. Current concerns about the global food security need to encompass the issue of breeding for nutritional quality of food plants. One of the issues that revolve around the nutritional quality is the presence of antinutrients. These substances reduce the bioavailability of nutrients such as proteins, vitamins and minerals which could result in malnutrition especially in developing countries. Designing breeding programmes for the enhancement of nutritional quality of food crops require information on the types and concentrations of these antinutrients in such crops. This study was thus initiated to obtain information on the concentrations of the antinutrients - cyanogenic glycosides, oxalates, phytic acids, tannins and alkaloids - of Annona muricata (a fruit), Corchorus olitorius (a vegetable/grain crop) and Pentaclethra macrophylla (a legume) which are common among the local people of South East of Nigeria. Results showed that mean contents of oxalate, phytic acid, tannins and alkaloids were within permissible limits while high contents of cyanogenic glycosides were observed in C. olitorius (0.551 ± 0.0165 mg/100 g) and P. macrophylla. Fermentation did not reduce the level in P. macrophylla. The values obtained in unfermented and fermented seeds were 0.577 ± 0.0004 mg/100 g and 0.575 ± 0.003 mg/100 g respectively. The results were discussed bearing in mind the need for plant breeders and nutritionists to design programmes that will balance the adverse and beneficial effects of these antinutrients since many of them have also been found to be pharmacologically beneficial.
