Abstract
The present study was conducted to know the effect of extracts from parts of papaya and pomegranate fruits containing enormous amount of antioxidants on the seed quality parameters of blackgram (Vigna mungo L.). Blackgram seeds were soaked in papaya peel, pulp, seeds and pomegranate peel, seeds extracts viz., 2.5 %, 5 %, 7.5 % and 10 % concentration for 1 hour. The physiological parameters were evaluated under laboratory conditions. The results revealed that seeds treated with 2.5 % papaya seed extract recorded high physiological and biochemical changes in terms of field emergence, germination percentage, seedling length, dry matter production, vigour index and ?- amylase activity when compared to rest of treatments and control.
Highlights
Blackgram (Vigna mungo L.), the third most important pulse in India, called urdbean is having a rich source of protein about 26 %
The results revealed that seeds treated with 2.5 % papaya seed extract recorded high physiological and biochemical changes in terms of field emergence, germination percentage, seedling length, dry matter production, vigour index and α- amylase activity when compared to rest of treatments and control
Seed treated with papaya peel extract at different concentrations showed significant differences in seed germination, root length, shoot length, dry matter, vigour index I and vigour index II
Summary
Blackgram (Vigna mungo L.), the third most important pulse in India, called urdbean is having a rich source of protein about 26 %. It contributes a major share of protein requirements to the population in India. It is taken as split and the whole grain and it is crucial for supplement of cereal based diet. Presowing treatment which help in enhancing seed quality like uniform germination, vigour, viability and optimum plant stand in the field. Priming means seeds were partially hydrated so that pre - germinative metabolic mechanisms will be started, the radicle protrusion will be prevented; at the point seed were dried at original moisture content [1]
