Abstract
After visible injury appeared in the soybean seedlings fumigated with certain concentrations of SO_2, the extent of injury ceased to increase as the fumigation continued, so the seedlings showed a certain degree of adaptation to SO_2. In relation to this phenomenon, two indexes of SO_2 injury, the increase of membrane permeability and the decline of TTCreduction ability, also showed some degree of recovery. SO_2 fumigation induced an increase of free amino acid content, which decreased to the level of the control with the prolongation of fumigation. It is suggested that the perturbed metabolic processes recovered somewhat. Pretreating with low SO_2 concentration increased the resistance of soybean seedlings to high SO_2 concentration. The content of SH group in leaves increased evidently and the SOD activity also increased to some extent. The analysis of isozymes showed that the level of two bands of SOD isozyme increased, and they sometimes didn't appear in the control. These increases showed an intensifying increase of the antioxidative ability which implied an increase of plant resistance to SO_2.
