| Abstract: | The modulate chlorophyll fluorescence kinetics of Pyramidomonas sp.under different heavy metal concentrations(Cu2+,Zn2+,Cd2+) and different time(24h,48h,72h,and 96h) were investigated with Water-PAM chlorophyll fluorometer.The main parameters determined in the present study included the maximal photochemical efficiency of PSII(Fv/Fm),the potential activity of PSII(Fv/Fo),the actual photochemical efficiency of PSII in the light(Yield),the relative electron transport rate(rETR),the photochemical quenching(qP)... |
