低温胁迫下不同磷营养对水稻叶片质膜透性及抗氧化酶活性的影响
Effects of Different Phosphate Fertilizer Application on Permeability of Membrane and Antioxidative Enzymes in Rice under Low Temperature Stress
摘要
Abstract
A pot experiment was conducted to investigate the effects of different level of phosphate fertilizer application on permeability of membrane and antioxidative enzymes in rice( non-chilling cv. Changbai 9 and chilling-tolerant cv. Jijing 81 ) under low temperature stress. The results showed that as the increasing of P fertilizer applica-tion,membrane permeability and MDA decreased and the increased in P-treated rice,but soluble sugar content,pro-line, peroxidase( POD) ,catalase( CAT) and superoxide dismutase ( SOD) increased and then decreased. Compared with the normal temperature treatment, appropriately increasing phosphorus can improve the content of soluble sugar, praline, add the activity of POD,CAT,SOD,and decline membrane permeability and MDA content in rice under low temperture stress. The increase rates of the soluble sugar,proline, POD,CAT,SOD for P treatment in non-chilling cv. Changbai 9 were higher than those in chilling-tolerant cv. Jijing 81 under low temperature stress, and membrane permeability and MDA content decreased even more. The results indicated that membrane permeability and antioxidative enzymes of rice can be improved by exogenous application of phosphorus, it is beneficial to increase the cold resistance of rice.关键词
