Abstract
[Objective]In order to provide a new way for preventing potato scab, this study was performed to analyze the effect of plant disease inducers on resistance induction against potato scab. [Method]Five kinds of plant disease inducers, HarpinEa, PBZ, VMA, BTH and SA, were used to screen out the optimal inducer and best inducer concentration based on infection rate, infection index and relative efficiency. The related physiological and enzyme activity indexes were determined at the best inducer concentration. [Result]The resistance effects of HarpinEa and PBZ inducers were not obvious. VMA, BTH and SA inducers had different effect of induced resistance on potato scab, and infection rate and infection index were dramatically declined. SA was the optimal inducer. The best inducer concentration was 1.00 mmol·L-1 and the relative control effect to the scab was 67.6% under this concentration. The indexes of SAFR and MDA descended, but the indexes of pigment, soluble protein and related enzymes activity were obviously higher than those of the control. [Conclusion]SA, as the optimal inducer for potato scab, will reduce the incidence of potato scab and improve the quality of potato when using 1.00 mmol/L SA to spray foliar during potato growing every seven days.
