Abstract
In order to explore the effects of the foliar spray exogenous plant growth regulators on the yield and flag leaf protective enzyme activities during filling stage,in this experiment,two rice varieties( Xiangyaxiangzhan,Zengchengsimiao) were used as tested materials,and a field experiment was conducted by spraying gibberellin( GA treatment),Brassinolide( BR treatment) solvent and water( CK) in rice breach period. The results showed that compared to spraying water( CK Treatment),the rice yield was increased by GA and BR treatments,the rice yields of Xiangyaxiangzhan and Zengchengsimiao with GA increased by 15. 98 % and 4. 83 %,respectively,and with BR significantly increased by 6. 48 % and 9. 78 %,respectively; In the whole period of filling stage,Malondialdehyde( MDA) contents of GA and BR treatments were significantly lower than that of CK treatment; Catalase( CAT) activity during the early filling stage( 10 days after heading stage) and Peroxidase( POD) activity during the late filling stage( Maturity) of GA and BR treatments were higher than that of CK treatment; Their superoxide dismutase( SOD) of GA and BR treatments was highly active than that of CK treatment during the whole period of filling stage. In the late filling stage,the soluble sugar content of GA and BR treatments were higher than that of CK treatment and showed a sharp rise in maturity. It was concluded that a certain concentration of foliar plant growth regulators application could improve the rice yield and protective enzyme activities in filling stage.
