| 摘 要： | 利用不同浓度外源水杨酸喷施处理玉米植株，再人工接种玉米纹枯病病原菌于其上，探讨外源水杨酸对玉米植株纹枯病系统抗性的诱导作用。结果表明，所有喷施水杨酸的处理均能使玉米植株纹枯病病斑面积和病情指数出现不同程度的下降，其中0．10mol／L处理的纹枯病病斑面积和病情指数下降幅度较大，与对照处理（0mol／L）相比达到了显著差异水平，是一个比较理想的外源水杨酸喷施处理浓度。通过了解外源水杨酸诱导玉米纹枯病的系统抗性或过敏性反应。有助于提高玉米纹枯病综合防治水平。 |

| Abstract: | Different concentrations of salicylic acid(SA) were used to treat maize plants,then the maize plants were inoculated with pathogen strains of maize sheath blight.The results indicated that all the treatments spraying SA could cause some reduction of sheath area and disease index.And the treatment of 0.10 mol/L concentration of SA was an ideal concentration because it caused a significant reduction of sheath area and disease index of maize sheath blight compared with the check.It showed that salicylic acid t... |
