林木化感物质研究进展
Review on Allelopathic Effect of Forest Trees

化感作用普遍存在于森林群落中，不同树种间的化感作用是决定营建混交林成败的关键因素。本研究从化感物质的来源、种类分离鉴定、释放途径、作用机制、影响因素等方面对近10 a来林木化感作用进行阐述，为林木群落的健康和生态功能评价提供理论基础和参考。建议今后加强和扩展对林木化感物质研究的深度和广度，对化感物质作用机制的研究层次可深入至分子和基因维度，将研究对象从单一植株化感潜力的测定拓展至探究特定植物种群化感物质对森林群落结构和物种多样性的影响上来。
Allelopathy commonly exists in forest communities，it is a key factor in determining the success in construction of mixed forest.The recent decade advances in the allelopathic effect on woody plants were reviewed in this paper.The category and mechanism of allelochemicals were introduced，and allelochemicals’ releasing pathways，extraction and identification were also illustrated，the main factors that influenced woody plants allelopathy were discussed.The theoretical bases and reference were supplied for forest tree ecosystem’s health cultivation and recovery of its ecological function.Accordingly it was proposed to strengthen and expand the depth and breadth of research on allelopathic effects of forest trees，the research level of the mechanism of allelochemicals should be deepened to the molecular and gene dimensions,and the research objects should be expanded from the determination of the allelopathic potential from a single plant to exploring allelopathic effects of on forest community structure and species diversity
