摘要
以玉米品种硕秋8(耐盐)、金刚5号(盐敏感)为实验材料,设置0、40、80、120mmol/L共4个NaCl浓度处理,从萌发期开始胁迫至幼苗期,对部分有机渗透调节物质进行研究。结果表明,两个品种可溶性蛋白、可溶性糖、游离脯氨酸、叶片中游离氨基酸含量均随NaCl胁迫浓度增加而增加;根系中游离氨基酸含量在120mmol/L浓度时显著高于其他处理,盐敏感品种的增加幅度不如耐盐品种增加的幅度大;盐敏感品种在NaCl胁迫下的渗透调节能力小于耐盐品种。
Shuoqiu8 （sah-tobrance） and Jingang5 （salt-sensitive） were tested to research some organic osmotica, setting the concentration of 0, 40, 80, 120 mmol/L, and staessed from germination to seedling stage. Results showed that the content of soluble protein, soluble sugar, proline and leaves＇ amino nitrogen of two varieties increased with salt stress concentration increasing, and amino nitrogen of roots at 120 mmol/L concentration marked higher than others. The salt-sensitive varieties＇ increased extent less than the salt-tolerance varieties＇. The organic osmotica ability of salt-sensitive variety was less than tsalt-tolerance variety.
