- Abstract
To identify the role of salicylic acid ( SA ) in peanut induced resistance to peanut web blotch, the content of endogenous SA in leaves and roots of peanut plants were measured by Enzyme - Linked Immunosorbent Assay (ELISA) method. Then the changs of SA content in leaves at different location inoculated with 2% cultural filtrate of Phoma arachidicola were monitored, and their relationship with induced resistance were analyzed. The results indicated no significant differences in content of SA in leaves at diferent locations without inoculation at the same growth stage. However, the content of SA in leaf was higher than in roots. After treated with 2% culture filtrate, the content of SA reached its peak twice both in treated leaves and untreated nearby leaves. At first peak, there were no significant differences in both peak time and peak values between different leaves. At second peak, both peak time and peak values were closely related to leaves in different locations. It was concluded that SA played a significant role in peanut web blotch resistance and signal transduction.
