Abstract
The germination rate, germination index and vigor index of rice (Xiangwanxian 15 1 cultivar) seeds decreased after soaked in nickel nitrate solution of 0 25~1 00 μmol/L for 24 h. Meanwhile, the mean days of germination was elongated, and the growth of seedling roots and sprouts was inhibited, together with decrease of biomass. It indicates that nickel hinders the germination of seeds and the growth of seedlings. The activities of SOD, CAT and POX in rice seeds all decrease when treated with nickel nitrate of various concentrations, except that the activity of POX is enhanced by 0 25, 0 50 μmol/L nickel nitrate. The results also show that the contents of MDA and electrolyte leakage percentage increase after treatment of nickel.
