【摘要】 植物释放的挥发物是植物次生代谢产物,可由各种植物组织生产。植物是挥发性物质生产和释放的主体,虫害叶片众多挥发物的可控释放有助于植物阻止植食昆虫或者吸引它们的天敌,在植物—害虫—天敌三级营养关系中起着信号物质的作用。文章综合近年来国内外的研究进展,对具有信号功能的挥发物的种类、激发子、合成途径及其化学生态功能作一概述。更多还原

【Abstract】 The functions of plant volatiles as airborne signals are very interesting.The volatile compounds,produced by the various parts of plants,are the secondary metabolism products.In an agricultural ecosystem,plants are the principal part produced and emitted the volatiles.Controlled release of the volatiles from herbivore-damaged plants may help to deter herbivores to feed or attract their natural enemies,and play an important role in the nutrition relationships among plants-herbivores-natural enemies.Referring to the present advancement, the kinds,elicitors,synthesis pathway,and chemical ecological function of airborne signal compounds are reviewed in this paper.更多还原
