摘要
Abstract
In order to provide theoretical guidance for herbicide monitoring by algae, three kinds of algaes, Scenedesmus obliquus, Chlorella pyrenoidosa, Selenastrum capricornutum, are selected as research objects, and their Chlorophyll fluorescence variation law under stress of three typical herbicides are studied for evaluating the sensitivity of the parameters, and the response differences of three kinds algaes to the toxicity was discussed. The results show that the algaes are inhibited in different toxicities with various tolerance capacities under different toxicity concentrations; the Selenastrum capricornutum has higher sensitivity to the herbicide, which could be adopted as bio-indicator for monitoring.关键词
