摘要：The changes in the composition and content of root ex-udates are the most direct and obvious responses of plant responses toenvironmental stresses. Root exudates are of great significance forphytoremediation of contaminated soils. In this paper, the role of rootexudates in phytoremediation of contaminated soils is briefly intro-duced, and the mechanism of its interaction with heavy metals and or-ganic pollutants is briefly introduced. Based on the definition and clas-sification of root secretion, the mechanism and influencing factors ofroot exudates in phytoremediation of heavy metals and organic con-taminated soils are reviewed. This paper discusses the shortcomings inthis field and makes a prospect.
