Abstract
Using the autotetraploid rice IR36(4) as the material, the effect of low-energy(25 keV) N~+ implantation on seed germination was studied.The results showed that N~+ implantation promoted seed germination by increasing seed survival rate,seed water absorption and amylase activity in seedlings when the dosage was at 2×10~(16)N~+/cm~2,but it would inhibit seed germination by greatly decreasing seed survival rate and amylase activity of seedlings,and increasing membrane permeability when the dosage was increased to 4×10~(16)N~+/cm~2 or higher.
