Effect of pre-soaking seed treatments on seed quality in Ashwagandha (Withania somnifera Dunal.)

摘要

The pre-soaking seed treatments were given before sowing of seed. Pre-soaking seed treatments were carried out to assess the performance in seed quality parameters in laboratory. The higher germination percentage (76.00%) was recorded in the pre-soaking seed treatment of GA_3 400 ppm soaking for 6 hrs followed by (72.00%) GA_3 200 ppm soaking for 12 hrs and (69.33%) 1% KN0_3 soaking for 6 hrs. Seed quality parameters viz., shoot length (cm), root length (cm), seedling dry weight (g) and vigour indexwere improved by presoaking seed with GA_3400 ppm for 6 hr followed by GA_3200 ppm for 12 hr and 1% KN0_3for 6hr.
