摘要: 化感作用是生态学研究中的十分活跃的领域之一。除概述化感作用对于植物细胞、组织以及环境胁迫对于化感效应的影响外,本文主要讨论了在分子和土壤生态系统水平上的化感作用的研究。在分子水平化感作用研究中,主要从化感基因的定位、蛋白质和核酸合成、基因表达和调控以及生化机制等几个方面进行了论述。在化感作用对于土壤生态系统的影响方面,主要对其在土壤性质、土壤微生物和土壤动物方面的效应进行了评述。最后,并就化感作用研究中存在的问题和未来发展提出一些看法与展望。

Abstract: Allelopathy is one of the hottest research domains in ecology.In this paper,current advances of studies on allelopathy from molecular level to soil ecosystem level were reviewed.Effects of environmental stresses on allelopathy and impacts of allelopathy on plant cells and tissues were discussed.Recent progresses of the studies at molecular level were summarized in regard to locating gene controlling allelopathic effects,influencing protein and nucleic acid formation,gene expression and regulation,physiological and biochemical mechanism.Three aspects of the allelopathic effect on soil ecosystem perspective were also reviewed,which included soil quality,soil microorganism and soil fauna.Some problems and the further development on allelopathic research were put forward as well.
