Abstract: Six rice genotypes with different Zn efficiency were cultivated at different Zn2+ activities (pZn2+9.7，pZn2+11.0 and pZn2+>11.5) in nutrition solution. Effect of different Zn2+ activities on the growth and some physiological characteristics of leaf and root of rice were studied. It was found that t
