Abstract

The effect of growth and physiological functions of different concentration Al on the hybrid rice seedling was studied. The results showed that the growth of rice seedling was promoted at 50 μmol·L~(-1) of Al. But the seedling height, root length, fresh weight and dry weight decreased,rice growth distinct was inhibited, and the content of chlorophyll, activity of superoxide dismutase (SOD) decreased. Peroxidase (POD) had a resistant peak and decreased afterward, and cell membrane permeability increased when the concentration of Al were increased,which indicated that activity of protective enzyme such as SOD、POD decreased. The membrane system had been damaged by toxic of Al, so rice seedling growth was inhibited.
