Abstract

The germination rate of rice seeds was increased as a result of the treatment with 10mumol/L /CuSO_(4) or AgNO_(3). The activity of POD was enhanced and the content of Chl.b decreased after the seedlings grew for 24 hours in the nutrient solution plus 2mumol/L Cu~(2+) or Ag~(+), however, the POD activity dropped when the concentration of these two heavy-metal irons raised up to 20mumol/L.
