Seed quality enhancement of aged and fresh seeds of chilli (Capsicum annumm L.) with plant extracts, antioxidants and chemicals

Abstract

A laboratory experiment was conducted to study the effect of seed priming with plant extracts and antioxidants on seed quality of chilli in the Department of Seed Science and Technology, Raichur, during 2018-19. The experiment consisted of twenty treatments which includes organic and inorganic solutions were imposed at different concentrations. The experiment was laid out in CRD design with four replications. The results revealed that, among the various priming treatments studied, seeds primed with KNO3 @ 5%, moringa leaf extract @ 10% and salicylic acid @ 1 mM recorded significantly highest in terms of all seed quality parameters viz., field emergence, seed germination, speed of germination, shoot length, root length, seedling dry weight, seedling vigour index, electrical conductivity and dehydrogenase enzyme activity compared to control and other treatments in both aged and fresh seed lot.
