摘　　要：研究结果表明:β-氨基丁酸对水稻稻瘟病的最佳诱导浓度配比为浸种浓度1%,喷雾浓度为1 000μg/mL的组合,如果用单一方法,其浸种和喷雾最佳浓度分别为1%和1 000μg/mL。而且β-氨基丁酸的诱导效果因品种不同而存在差异,抗性越差其效果越好。The results of experiments showed that the best consistency of resistance on blast of rice induced β -Aminobutyric Acid was combined 1% seed soakage with 1000 μg/ml foliar spray. β -Aminobutyric Acid application included seed soakage and foliar spray, the optimum concentration was 1% and 1000 μ g/ml, separately. The effect varied with rice varieties, and induced resistance was better if the disease resistance of variety was worse.
