摘　　要：选用水杨酸(SA)、壳聚糖、β-氨基丁酸(BABA)和草酸4种诱抗剂处理绥农8和合丰25,研究这些试剂对大豆细菌性斑点病的诱导抗性。结果表明,4种诱抗剂均可诱导两个大豆品种对细菌性斑点病的抗性,其中1000μg/mL BABA对合丰25和绥农8诱抗效果最高,分别达84.92%和69.43%,诱抗效果因试剂的浓度及品种而异,药剂施用方法也影响诱抗效果,各试剂在适宜浓度下对合丰25的诱抗效果明显高于绥农8。Induced resistance of two soybean varieties of Suinong 8 and Hefeng 25 was induced by Salicylic acid（SA）, Chitosan, β-Aminobutyric-acid（BABA） and Oxalic acid to bacterial blight disease were studied. Results showed that four resistant inducers could induce Suinong 8 and Hefeng 25 to produce resistance to bacterial blight disease of soybean. The concentration of 1,000 μg / mL BABA induced highest resistance among all treatments, reached 84.9% and 69.4% for Suinong 8 and Hefeng 25,respectively. The inducers＇ concentration , soybean varieties and application methods all can vary the effect of induced resistance. The effects of induced resistance to Hefeng 25 were significantly higher than to Suinong 8 when the concentration of inducers were appropriate .
