摘要

采用不同浓度重金属Cu和Cd胁迫东洋Styrax幼苗，采用高效液相色谱法同时测定东洋Styrax根分泌物中有机酸含量，研究不同浓度重金属Cu和Cd对东洋Styrax根分泌物中有机酸含量的影响。结果表明，不同浓度重金属Cu和Cd对东宁Styrax根分泌物中有机酸含量影响较大，其中Cu胁迫后柠檬酸和琥珀酸含量几乎为零，Cd胁迫后草酸在相应浓度下影响最大。

Effects of Determination of Organic Acids Exuded from Styrax tonkinensis Roots under Heavy Metal Conditions

Using different concentrations of heavy metals Cu and Cd to stress the seedlings of Styrax tonkinensis , the organic acids in the root exudates of Styrax tonkinensis were simultaneously deter-mined by high performance liquid chromatography, and the effects of different concentrations of heavy metals Cu and Cd on the content of organic acids in the root exudates of Styrax tonkinensis were studied. The results showed that different concentrations of heavy metals Cu and Cd had great differences in the content of organic acids in the root exudates of Styrax tonkinensis , among which the contents of citric acid and succinic acid after Cu stress were almost zero, and oxalic acid after Cd stress had the greatest effect at the corresponding concentration.

期刊介绍： The main aim of the International Journal of Ecology & Development (IJED) is to publish refereed, well-written original research articles, and studies that describe the latest research and developments in ecology and development. It also covers the many potential applications and connections to other areas of Ecological Science, economics and technology such as the use and development of mathematics/statistics in ecology or use and development of economics for ecology & development or inter-disciplinary nature of applications for Ecology & Development. International Journal of Ecology and Development is published three issues in a year in Winter, Summer and Fall.
