摘要：Effects of various concentrations of copper on growth change of bluc-greenalgae Anabaena flos aquae were studied. There was significant differences among cultures treated with various concentrations of copper in growth of algae with parameters of cell numbers,specifie growth rate (SGR) and chlorophyll contents. Algal growth and SGR were inhibited on by efct of various concentrations of copper more than without copper (ANOVA,F=34.69 p<0.001,F=114.89,p<0.001). The SGRs of various concentrations of copper in media were higher than without copper on 8 days after copper treated. The mean of chlorophyll contents was 1.978 μg° mL-" and 1.648 ug . mL-',respectively,while those of algae in culture without copper was 3.179μg° mL' (ANOVA,F= 153.74,p<0.001). The cellular morphology was different between media of which copper treated and without copper. The colony of algae in media which copper treated was shorter than without copper. Effects of various concentrations of copper on growth change of blue-green-algac Anabaena flos-aquae occured variety changes of parameters of cell numbers,specific growth rate (SGR),chlorophy'll contents and cellular morphology on growth of algac.
