The α-amylase, β-amylase and total amylase activity of rice seedlings. α-amylase activity in shoot (a), α-amylase activity in the seedling (b), β-amylase activity in shoot (c), β-amylase activity in the seedling (d), total amylase activity in shoot (e), total amylase activity in the seedling (f). ZnO NPs 0, ZnO NPs 25, ZnO NPs 50 and ZnO NPs 100: 0, 25, 50 and 100 mg L−1 of ZnO NPs. Cd 0 and Cd 100: 0 and 100 mg L−1. Values were represented as mean ± SD (n = 4). Different low case letters among the treatments within a variety shows the statistically significant at p < 0.05 according to least significant different test
