Abstract

Abstract:

The effects of cadmium(Cd) on photosynthesis and chlorophyll fluorescence parameters were studied in poplar plants. Experiments were carried out with poplar cutting plants of clone XMH-4(Populus deltoides×P. nigra),MH-8(P. trichocarpa × P. deltoides) and XMH-10(P. deltoides × P. nigra) treated with 0, 25, 50, 100 μmol·L^-1Cdsolution for 5 months under normal conditions in greenhouse. The result showed that cadmium significantly decreased chlorophyll，photosynthesis and quantum yield of PSⅡphotochemistry. The contents of calcium(Ca), iron(Fe), magnesium(Mg) and copper(Cu) all increased with the 25, 50 μmol·L^-1 Cdtreatments, only manganese(Mn) showed a robust negative relation with Cdconcentration. It was suggested that some problems occurred to the electron transport chain at the oxidation side of PSⅡreaction centres(RCs), and the cadmiuminduced etiolation were not caused by lack of iron or magnesium, but manganese. Therefore manganese may play an important role in cadmium stress to plant.
