The ability of SAR-associated molecules to induce resistance in cucumbers to Pseudomonas syringae pv lachrymans (lab-grown) and powdery mildew (greenhouse-grown), was investigated. Single treatments with glycerol, azelaic acid or pipecolic acid elicited modest levels of resistance in lab experiments, while single treatments with Actigard elicited high levels of resistance in both lab and greenhouse experiments. Multiple treatments with pipecolic acid elicited modest to high levels of resistance in lab-grown plants, but not in greenhouse-grown cucumber. SAR marker gene expression was observed in pipecolic acid-treated lab-grown cucumber plants. This knowledge may inform methods to protect greenhouse crops against disease.

考察了SAR相关分子诱导黄瓜对丁香假单胞菌pv lachrymans（实验室生长）和白粉病（温室生长）的抗性的能力。在实验室实验中，用甘油，壬二酸或胡椒酸进行的单次处理引起中等程度的耐药性，而在实验室和温室实验中，用Actigard进行的单次处理引起很高的耐药性。胡椒酸的多次处理在实验室种植的植物中引起中等程度的高抗药性，但在温室种植的黄瓜中则没有。在胡椒酸处理的实验室种植的黄瓜植物中观察到SAR标记基因的表达。这些知识可以为保护温室作物免受疾病侵害的方法提供参考。
