ORGANIC SEED TREATMENT WITH SEAWEED NANO POWDERS WEED NANO POWDERS ON PHYSIOLOGICAL QUALITY AND ENZYME ACTIVITIES IN AGED SEEDS OF PIGEON PEA

Abstract

In the present study the organic seaweed nano powders treatment were imposed to elucidate their effects as presowing treatments. In another experiment, the same treatments were imposed on the seeds and the treated seeds were subjected to accelerated ageing for three days (treated-aged) to assess their performance as pre-storage treatment. The seaweed nano powders treatments were also given to aged seeds (aged-treated) to identify the efficacy as mid-storage treatments. The results of the present investigation revealed that, the seeds treated with Sargassum myricocystum (1%- 3 h) performed better than other treatments and control. The per cent increase over control for higher speed of germination, germination, seedling length, dry matter production, vigour index, á- amylase and peroxidase in fresh (20, 10, 18, 16.7, 26.5, 21.3 and 20.7, respectively), treated aged (32.8, 12.5, 29.3, 19.4, 38.1, 21.4 and 24.5, respectively) and aged treated seeds (29.1, 6.6, 24.4, 22.4, 29.5, 17.9 and 13.5, respectively).
