摘要: 为探明荒漠生态系统中植物之间的化感作用,首次对近年来该领域所取得的研究成果、已报道的化感植物、化感物质以及化感物质释放途径等进行总结,认为:(1)中国有关荒漠植物化感作用的研究才刚刚起步,在该区菊科、豆科、蔷薇科、玄参科、禾本科等科属中发现具有化感潜势的植物。(2)荒漠植物化感物质释放的途径以自然挥发为主,这主要与其生长环境有关,鉴定出的化感物质有生物碱、黄酮类、萜类等化合物。(3)最后指出荒漠生态系统中化感植物研究存在的关键问题,对确定合理的荒漠植物保护措施及荒漠化综合治理提供理论依据和实践价值。

Abstract: To investigate the allelopathy among the plants in the desert ecosystem, this article summarized research achievements in this field in recent years, as well as the reported allelopathy plants, allelochemicals and alleochemicals’release way for the first time. It was considered that: (1) China’s research on desert plants’allelopathy was just at the beginning stage, and allelopathic potential plants were found in the Compositae, Leguminosae, Rosaceae, Scrophulariaceae and Gramineae; (2) the release way of desert plant allelochemicals was mainly natural volatilization, which was related with the growing environment, allelochemicals including alkaloids, flavonoids and terpenoids were identified; (3) finally, key problems of allelopathy plants research in desert ecosystem were pointed out, and the theoretical and practical bases for reasonable protection of desert plants and comprehensive control of desertification were put forward.
