Modification in Physiological Performances of French Bean (Phaseolus vulgaris L.) Seed Through Seed Priming

Abstract

Background: The three priming modes using various organic and inorganic compounds for hydro-priming, osmo-priming (PEG 6000, CaCl2, KNO3) and halo-priming (thiourea, GA3) with control were considered, to study the improvement in physiological performances of French bean seed. Methods: The seeds were primed for 6 hours duration and observations associated to seven parameters considering seedling and biochemical activities were considered for getting the real exposure in physiological performances of seed for seedling establishment. Result: The treatment, T2 (thiourea, 750 ppm) was best performing with significant variation among diverse treatments except in peroxidase activity. In genotypes, V3 (RCM-FB-62) showed high significant demarcation for maximum parameters though, V2 (phyrngop) and V1 (RCM-FB-18) were highest for peroxidase activity and speed of germination. The treatment-genotype interactions showed significant demarcation with exemption in speed of germination and vigour index, however, T2V3 interaction was highest considering all parameters. Considerable parameters were pronounced contributors for cumulative upgradation in physiological performances of seed with exceptions in percent of germination and peroxidase activity. Diverse treatments specified the extent of effects on seedling or enzyme activity to upgrade the quality. Consequently, the treatment T2 resulted in improved physiological performance in French bean seed production.
