摘要: 植物与其它有机体种间存在着通过次生物质为媒介的化学作用,这些化学作用在农业生态系统中则表现为植物对有害生物的化学防御。面对动物取食、微生物侵染和其它植物竞争,植物能合成释放特定的次生物质抵御侵害。而且,植物这种对有害生物的化学防御机制常常是在侵害条件下诱导产生的。当前的研究显示,作物/害虫/天敌三营养食物链也有自然的种间化学作用关系操纵,作物和杂草种间除了有相互抑制的化感作用外,还存在着通过次生物质进行的信息传递关系。揭示并充分利用植物这种内在的化学防御机制不仅能拓宽认识植物与其它有机体种间关系的视野,而且能开拓植物保护的新途径。

Abstract: There are chemical interactions manipulated by plant secondary metabolites between plant and other organisms, which act as plant chemical defense on pests in cropping ecosystems. Under herbivore, infestation and competition, plants may trigger the defense mechanism producing and releasing allelochemicals to resist or inhibit the pests. Furthermore, the chemical mechanism of plant defense may be induced under pest stress. Recent studies have showed that there are manipulating interactions through allelochemicals in tri-trophic systems that include the host plant, herbivore, and parasitoid or predator. Besides allelopathy between crops and weeds, chemical recognition and information transfer may occur among inter-and intra-plant species. Clarification of chemical interactions between plant and other organisms not only widen the insight of species interactions, but also develop new strategy for pest control. This paper reviewed prospects for application in plant protection using chemical interactions between plant and other organisms.
