Genetic variation has a profound effect on the nutritional and anti nutritional profile of pulses. Thus, investigating this fact, comparison of five desi and four kabuli varieties of chickpea were done to assess the effect of genetic variation on the anti nutritional factors, bioavailability of minerals and the influence of hydrothermal (autoclaving, microwave cooking, boiling) and dry roasting processing methods. Results showed that large variability exist in antinutritional and mineral content of selected chickpea cultivars. Antinutritional factors (viz. phytate, tannin and trypsin inhibitor's content) was found significantly (p<0.05) higher in all desi cultivars of chickpea than their kabuli counterparts. All hydrothermal, thermal and bio processing treatments were found to reduce antinutritional factors in all the cultivars of chickpea. Molar ratios of phytic acid with zinc and iron were high in all selected chickpea cultivars which showed poor bioavailability before processing. The bioavailability of iron and zinc were significantly (pd"0.05) improved as a result of all hydrothermal and thermal processing treatments which were applied in this study. Bioavailability of Fe and Zn was higher in case of kabuli cultivars (8.1% and 40.5%, respectively) than desi cultivars (5.5% and 38.4%, respectively). The most pronounced increment among all the processing treatments of in vitro bioavailability of iron and zinc was with autoclaving treatment (17.5 to 30.9% and 25.6 to 41.4%, respectively) followed by microwave cooking, boiling and roasting. Hydrothermal processing treatments particularly autoclaving shows highest reduction in antinutritional factors and improvement in the availability of iron and zinc in all the cultivars of chickpea. Therefore, promotion of suitable cultivars and proper processing treatment should be encouraged.
Salinity is one of the major abiotic stresses that limit productivity of pulse crops all over the world. Seed priming with phytohormone(s) is one of the most promising, authentic and cost-effective methods to mitigate the deleterious effect of salinity.• The study was conducted to investigate potential of seed priming with gibberellic acid (GA 3 ) to cope up with the adverse effects of salinity (0, 100, 200 and 300 mM NaCl) in pea (Pisum sativum L.) seedlings.• There were different responses to salinity, which induced oxidative stress, higher accumulation of Na + in shoots and roots and inhibition of photosynthetic traits. However, seed priming with GA 3 showed promising effects on physiological traits under salinity stress and alleviated the adverse effects of salinity by inducing the antioxidant system, proline production, total phenol and flavonoid content and regulating ion homeostasis, along with up-regulation of Na + /H + antiporters (SOS1 and NHX1).• Plants adapt and prevent high salt accumulation by inducing expression of Na + / H + antiporter (SOS1 and NHX1) proteins that enhance Na + sequestration. Thus, seed priming with GA 3 is important in alleviation of high salinity stress and can be used as a criterion for developing salt-tolerant cultivars.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
