Maintenance of Vigour and Viability of Stored Pea ( Pisum sativum L.) Seeds

Maintenance of Vigour and Viability of Stored Pea ( Pisum sativum L.) Seeds To determine the most efficacious midstorage hydration‐dehydration treatment for preservation of vigour and viability of stored pea seeds (Pisum sativum L.), cultivar Bonneville, three methods viz., soaking‐drying, moisture equilibration‐drying and moist sand conditioning‐drying each at varying durations were evaluated. Irrespective of the durations of treatment, soaking‐drying proved injurious. Though all durations of moisture equilibration excepting and 120 h outperformed the control, yet 48 h proved to be the best. Preconditioning with moist sand (5 % moisture content) with seed at a ratio of 1: 2.5 for different durations revealed 48 h to be the optimum, 72–96 h to be innocuous and thereafter injurious. Maintenance of membrane integrity and counteraction of lipid peroxidation may be the possible reasons for such beneficial effects. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Agronomy and Crop Science Wiley

Abstract

To determine the most efficacious midstorage hydration‐dehydration treatment for preservation of vigour and viability of stored pea seeds (Pisum sativum L.), cultivar Bonneville, three methods viz., soaking‐drying, moisture equilibration‐drying and moist sand conditioning‐drying each at varying durations were evaluated. Irrespective of the durations of treatment, soaking‐drying proved injurious. Though all durations of moisture equilibration excepting and 120 h outperformed the control, yet 48 h proved to be the best. Preconditioning with moist sand (5 % moisture content) with seed at a ratio of 1: 2.5 for different durations revealed 48 h to be the optimum, 72–96 h to be innocuous and thereafter injurious. Maintenance of membrane integrity and counteraction of lipid peroxidation may be the possible reasons for such beneficial effects.
