植物之间的挥发性通讯引起增强防御一直是有争议的。早期的研究没有被复制，有影响力的评论质疑这一现象的有效性。我们收集了48项重复性很好的研究，发现总体上支持这一假设，即邻居受损的个体的抵抗力会增加。实验室或温室研究以及对农作物进行的研究表明，诱导抗性比对未驯化物种进行的实地研究更强，这可能是因为其他变异减少了。一项累积分析显示，早期的非重复研究变量更多，沟通的证据较少。生境和植物生长形式的影响是不可检测的。在大多数情况下，没有考虑耐药机制和替代假设。没有迹象表明，一些反应变量更有可能产生大的影响。这些结果表明，植物的不同分类的亲和力和生态条件变得更耐食草动物暴露于挥发物从受损的邻居。
Volatile communication between plants causing enhanced defence has been controversial. Early studies were not replicated, and influential reviews questioned the validity of the phenomenon. We collected 48 well-replicated studies and found overall support for the hypothesis that resistance increased for individuals with damaged neighbours. Laboratory or greenhouse studies and those conducted on agricultural crops showed stronger induced resistance than field studies on undomesticated species, presumably because other variation had been reduced. A cumulative analysis revealed that early, non-replicated studies were more variable and showed less evidence for communication. Effects of habitat and plant growth form were undetectable. In most cases, the mechanisms of resistance and alternative hypotheses were not considered. There was no indication that some response variables were more likely to produce large effects. These results indicate that plants of diverse taxonomic affinities and ecological conditions become more resistant to herbivores when exposed to volatiles from damaged neighbours.
