Effect of various seed priming techniques on seed physiology and vigor association in baby corn (Zea mays L)

Abstract

Seed priming is one of the most common and economical methods to enhance seed quality. One of the major challenge of seed deteoriation can be also overcome by priming method. There are several type of priming out of which four type Hydro priming, Osmo priming, Halo priming, Hormonal priming were evaluated on baby corn fresh and artificial accelerated aged seeds and were compared with each other. Several physiological character determining seed quality were observed like germination percent, germination speed, seedling length, seedling dry matter and vigor index. But use of G.A3 a@ 150 ppm for 24 h was most effective in all priming treatment followed by other. Hydro priming methods was also useful and it is easy to use. All priming method showed better results in compare to unprimed seeds in both slot but however Hormonal priming proved best out of all followed by Hydro priming.
