    摘要:

    综述了根系分泌有机酸种类、组成含量、来源、分析检测方法、影响因素及其作用。根系分泌有机酸是植物应对环境胁迫的一种适应性响应机制,在许多环境胁迫下诸如养分胁迫、水分胁迫和重金属胁迫条件下,植物通过根系释放有机酸到根际土壤中,不仅可以改变土壤的理化性质及微生物活性,还会影响土壤-植物界面的许多生理生化过程。通过深入研究不同环境胁迫对根系分泌有机酸的影响及机制,有助于更深层次地研究植物在逆境胁迫下的适应性机制。

    Abstract:

    This paper summarized the kinds, components, concentrations, source, influencing factors and role of root-exuded organic acids and their analysis methods. Variations of organic acids in root exudations are important mechanisms in response of plant roots to environmental stress. In many environmental stresses such as nutrient stress, water stress and heavy metal stress, the organic acids released into rhizosphere from plant roots not only changed the physicochemical properties of rhizosphere soil and microorganism activity, but also influenced many physiological and biochemical processes in soil-plant interface. The further investigations on the effect and mechanism of different environmental stresses on root-exuded organic acids will benefit to understand the adaptive mechanisms of plants to adverse environment stresses.
