Abstract

Seed priming is the seed invigoration treatment which can increase the germination potential of the poorly geminating seeds accompanied with increase in vigor leading to the production of healhy seedling which in turn well give rise to healthy plants. Due to long term effect of priming these healthy plants are expected to bear better quality seeds will high germination values. Therefore, seed germination studies were carried out in seeds borne by healthy plants, which were initially produced from the seeds treated will different priming agent such as polyethylene glycol (PEG) 6000@ 300 g/L (P1), GA3@20 mg/L (P2), Bio priming with Trichoderma viridi @ 8 g/kg of seeds (P3), hydro priming (with water) (P4) and control (non primed seeds (P5). Such were harvested separately from the different seed priming plots and kept for germination in the seed germinator according to the treatments. The germination attributes were improved tremendously in the seeds which were harvested from plants produced from primed seeds. Among all the treatments, seeds produced from GA3@20 mg/L treatment were more vigorous w.r.t. germination percentage, seedling length, vigor index, seedling fresh weight, seedling dry weight and minimum seedling moisture contents. The lowest values for germination percentage, seedling length, seedling vigor index, seedling fresh weight, seedling dry weight and maximum seedling moisture contents recorded in the seeds which were harvested from non primed or control seeds.
