Abstract

The effect of copper stress on the growth, leaf area, dry weight and photosynthetic pigments content in Raphanus sativus L. was studied. The plants were grown in earthen pots containing soil amended with different concentrations of Cu (50, 100, 150,200, 250 mg kg-1) as CuSO4. Growth parameters viz., root and shoot length, total leaf area, dry weight of root and shoot and photosynthetic pigments content (chlorophyll-a, chlorophyll-b, total chlorophyll and carotenoid) increased at a concentration of 50 mg kg-1. However, further increase in the copper level in the soil (100-250 mg kg-1soil) showed a negative effect on these parameters.
