Abstract
To probe into the mechanism by which polyamines enhanced the tolerance of rice to drought,the effects of exogenous Put and MGBG on polyamines and antioxidant system in rice seedlings under osmotic stress were investigated.The results are as follow: Under osmotic stress,MDA and H2O2 level increased significantly in 'xianzaoxian 32' seedlings,while 'jiazao 935' showe a significant increase in Put,Spd,Spm and Vc level and activities of SOD,POD.Exogenous Put treatment which improve significantly Put,Spd,Spm and Vc level and activities of SOD,POD in seedlings of 'jiazao 935'.Exogenous MGBG treatment which inhibite markedly Put,Spd,Spm and Vc level and activities of SOD,POD,and promote significantly MDA and H2O2 level in seedlings of 'xianzaoxian 32'.Through correlation analysis,it showe positive correlation between Put,Spd,Spm and SOD,POD,Vc,meanwhile showe negative correlation between SOD,POD,Vc and H2O2.
