NaCl胁迫对玉米幼苗脯氨酸和可溶性蛋白质含量的影响
Effects of Different NaC1 Concentration Stresses on the Contents of Proline and Soluble Proteins of Maize Seedlings
摘要
Abstract
Variance of proline and soluble protein contents of different salt tolerant maize cultivars under NaCl stress was studied by sand culture experiment. Maize seeds of a salt tolerant cultivar Zhengdan 958 and a salt sensitive cultivar Qidan 1 were germinated and grown in sand with 0, 0. 2%,0. 4%,0. 6%,0. 8% and 1.0% NaCl, respectively, and then the contents of proline and soluble protein in leaves were measured. The results showed that variance between varieties, NaCl concentrations and days of NaCl stresses reached a significant level of the contents of proline and soluble protein. The contents of proline and soluble protein in two maize varieties were higher under NaCl stress than the control. The proline content of Zhengdan 958(121. 5μg/g) was significantly higher than Qidan 1(36. 2μg/g). From the 7th to the 15th days under NaCl treatment, the soluble protein content of Zhengdan 958 exhibited a trend to increase first and then decrease, while the soluble protein content of Qidan 1 gradually declined. It concluded that the contents of proline and soluble protein could be used for maize salt-tolerance identification.关键词
