EFFECT OF SEAWEED EXTRACT SM3 (SEAWEED EXTRACT) ON SEED GERMINATION AND SEEDLING GROWTH IN CANAVALIA GLADIATA (LEGUMINOSAE - PAPILIONOIDEAE)

摘要

Effect of seaweed extracts SM3 seaweed extract in different concentrations (0.5,1.0,1.5,2.0 & 2.5%) on seed germination and seedling growth of Canavalia gladiata (Jacq.) DC have been studied. The results indicate that all concentrations of seaweed extract SM3 treatments have not only promoted seed germination but also stimulated early seedling growth. Seaweed treated plants were compared to control. There was a progressive increase in germination with increasing concentrations of SM3 as well as seedling growth. Maximum germination percentage and seedling growth was observed in 1.5%. Minimum growth was noted in 2.0 and 2.5% level.
