| Abstract: | The chlorophyll fluorescence characteristics of Barbula subcontorta Broth.and Marchantia polymorpha L.under different Pb2+concentrations of 0,25,50,100,200 mg/L were menstruated by using the chlorophyll fluorescence measuring technique.The results showed that maximum photochemical efficiency(Fv/Fm),maximum fluorescence(Fm),background fluorescence(Ft),initial fluorescence in the light-adapted state(Fo'),maximum fluorescence in the light-adapted state(Fm'),photochemical quenching coefficient(qP),effective qua... |
