Effect of Aging and Priming on Physiological and Biochemical Traits of Common Bean (Phaseolus vulgaris L.)

Abstract

Aging and deterioration (artificial aging) are the most effective factors on the seed vigour. In order to study the changes in physiological and biochemical characteristics of common bean under aging and priming treatments a factorial experiment based on completely randomized design conducted with three replications. Seed aging (control, 90 and 80% of control germination) and seed invigoration with priming including control, hydro (distilled water), osmo (PEG 6000), hormone (gibberellic acid) and halo (NaCl) priming were considered as experimental factors. Results showed that osmo-priming had the ability to relatively ameliorate the aging effect and recover some of the seed aspects like germination rate, protein and phytin content for invigorate germination and seedling establishment. Priming indirectly increased seed vigour via germination rate and it can provide homogeny of emergence in the field and obtaining appropriate plant population.
