Abstract: In order to study the effect of Streptomyces JD211 fermentation products on the induced resistance of rice, the leaves were induced by Streptomyces JD211 fermentation products and exhibited obvious resistance to Magnaporthe grisea. Rice seedlings were treated with different concentrations of Streptomyces JD211 fermentation products, and the dynamics of MDA contents and activities of defense enzymes in the rice leaves were measured. The results showed that the activities of CAT, POD and PAL in rice leaves could be improved by different concentrations of Streptomyces JD211 fermentation products, as well as the MDA content. The 20% Streptomyces JD211 fermentation products showed the most significant effect.

Key words: Streptomyces JD211, rice, defense enzyme, induced resistance
