摘　　要：研究了不同Cd^2+浓度(0.25,0.50,0.75,1.00 mg/L)对水华微囊藻的生长、叶绿素和3个主要叶绿素荧光参数的影响。结果表明,0.25 mg/L Cd^2+浓度明显促进水华微囊藻生长和叶绿素a的合成(P<0.05)。0.75和1.00 mg/L Cd^2+浓度抑制了水华微囊藻的生长和叶绿素a的合成(P<0.05)。0.25和0.50 Cd^2+mg/L浓度对水华微囊藻Fv/Fm、Fv/Fo无明显影响(P>0.05),1.0 mg/L Cd^2+浓度明显抑制了水华微囊藻的Fv/Fm、Fv/Fo和YⅡ值(P<0.05)。The changes of growth,chlorophyll a and chlorophyll fluorescence parameters of Microcystis Flos-aquae were studied under different Cd2+concentrations(0.25,0.50,0.75,1.00 mg/L).The results showed that the concentration of 0.25 mg/L Cd^2+had significant effects on the growth and chlorophyll a content of Microcystis Flos-aquae(P<0.05).While the concentration of 0.75 and 1.0 mg/L of Cd^2+significantly inhibited the growth and the the synthesis of chlorophyll a(P<0.05).The concentrations of 0.25 and 0.5 Cd^2+mg/L had no significant effects on Fv/Fm and Fv/Fo of Microcystis Flos-aquae(P>0.05),while the concentrations of 1.0 mg/L Cd^2+inhibited Fv/Fm、Fv/Fo and YⅡof Microcystis Flos-aquae(P<0.05).
