根分泌物有机酸的研究方法

Research Methods on Organic Acids in Root Exudates

根分泌物主要是以碳为基础的低分子化合物和高分子化合物。植物分泌的有机酸主要有乙酸、草酸、柠檬酸、苹果酸、酒石酸和琥珀酸等,它们调节细胞代谢,为根际和微生物提供营养。植物根系分泌有机酸的研究对于了解植物的根际效应具有重要的学术意义。简述了根系分泌物有机酸的收集、分离和检测方法。

Root exudates include low molecular compounds,high molecular compounds,and primarily carbon-based compounds.The organic acids secreted by plants are mainly acetic acid,oxalic acid,citric acid,malic acid,tartaric acid and succinic acid,which regulate cell metabolism and provide nutrients for the rhizosphere and microorganisms.The study of plant root exudates of organic acids has important academic significance for understanding the rhizosphere effects of plants.This paper briefly described the methods of collection,separation and detection of organic acids in root exudates.
