Abstract
The effect of PP 333 on the resistance of rice seedlings to chilling injury was investigated.It was found that soaking with PP 333 caused remarkable of electrolyte leakage from rice seedlings during chilling (4℃±0.5℃) treatment.In the mean time,the decline of the activity of superoxide dismutase was slower and the content of malondialdehyde was lower in treated seedlings than the control.And peroxidase,catalase activity was increased.PP 333 enhanced the accumulation of proline of chilling treatment.Our results show that the stability of cell membrance and the osmo regulation caused by PP 333 may explain the resistance of rice seedlings to chilling injury.In the mean time,it can make rice seedlings growth low and make it strong.
