Impact of seed priming with fruit parts extracts on biochemical parameters in blackgram seeds (Vigna mungo L.)

Abstract

The present investigation was carried out to know the impact of papaya and pomegranate fruit part extract on the seed quality parameters of blackgram. The blackgram variety CO 6 was soaked in papaya peel (5%), papaya pulp (5%), papaya seed (2.5%) and pomegranate peel (7.5%), pomegranate seed (2.5%) extracts for one hour. The treated seeds along with control and hydroprimed seeds were evaluated for the enzyme activity under laboratory condition. The study revealed that the seed treated with papaya seed extract 2.5 per cent showed the higher activities of enzymes like dehydrogenase (2.79 OD value), catalase (4.19 μmol H2O2 min-1 g-1 protein), peroxidase (3.13 U mg-1protein min-1), antioxidant activity (81.66%) and superoxide dismutase (71.03 U mg-1 protein min-1) as compared to other treatments and control seeds.
