Effect of seed priming on physiological changes associated with seed deterioration during storage periods in soybean (Glycine max L. Merill.)

Abstract

This study was carried out in order to evaluate effect of seed priming on physiological changes associated with seed deterioration during storage periods in soybean (Glycine max L. Merill.) in Junagadh Agricultural University, Junagadh, in 2017. The experimental design was two factors factorial on basis of completely randomized block design with three replications. The first factor was genotypes (GJS-1, JS-20-29 and JS-335) and the second factor was seed priming treatments (control, cow urine (100%), cow urine (50%), KH2PO4 (2%), KH2PO4 (1%), KNO3 (2%), KNO3 (1%), CaCl2 (2%), CaCl2 (1%) and neem leaf extract (50%)). Results showed that seeds of the genotype JS-335 primed with CaCl2 (2%) was better in germination percentage, viability test and electrical conductivity throughout the storage period followed by those KH2PO4 (2%) primed seeds of JS-335 genotype. While its non-significant effect on seedling length, seedling dry weight, vigour index-I, vigour index-II and accelerated ageing percentage.
