Abstract
Soybean seeds were retreated with different concentration of PEG 6000. The result showed that the germination rate and vigour index of soybean seed pretreated increased notably, and the conductivity rate decreased compared to the control, and the pretreatment with 20% PEG (W/W) for 8 hours was the most effective. During germinating period, the respiratory intensity was lower than that of the control at the first, but increased rapidly afterwards; the rate of O - 2 · production was lower than that of the control, the specific activity of superoxide dismutase (SOD) and the activity of peroxidase (POD) all increased, while the accumulation of MDA was lower than those of the control. This indicated that the increasing of vigour index through pretreatment with PEG have interned relations with the increasing of avtivity oxygen metabolism.
