摘    要:植物的根际是一个复杂的微生态系统,植物的根必须与入侵的邻近植物根及大量以有机物质为营养的细菌、真菌、土存害虫相互竞争空间、水分、矿质营养等。在土壤中,根与根际生物体的相互作用相当复杂且受到许多土壤因素的影响,地下根际生物体以根分泌物为媒介相互作用的机制比发生在地表的生物体的相互作用复杂的多。越来越多的试验表明,根分泌物在根与根、根与根际微生物间起着重要作用,并以其为媒介在植物与环境的相互作用中起着传递信息的作用。本文在简要综述前人研究的基础上,深入探讨了化感植物根际生物学问题及攻克途径,以期为深入研究植物化感作用提供依据。

关 键 词:根际  化感作用  化感物质  自毒作用  根际微生物  根系分泌物

Abstract:Rhizosphere is the densely populated area of the soil where plant roots must compete with invading root systems of neighboring plants and soilborne microorganisms including bacteria,fungi and insects that feed on organic materials for space,water,and mineral nutrients.Interactions within the rhizosphere are based on complex exchanges involving surrounding plant roots and are highly influenced by edaphic factors.However,below-ground biological interactions that are driven by root exudates are more complex than above-ground interactions.Increasing evidence suggests that root exudates act as information transmitter in the interaction process between plants and their environment and thus play an important active role in root-root and root-microbe communication.In this paper,previous studies are vividly reviewed and the direction of future research disscused.
Keywords:Rhizosphere  Allelopathy  Allelochemicals  Autotoxicity  Soil-borne microorganism  Root exudates
