粳稻品种苗期耐盐指标分析及品种耐盐力鉴定

Salt Tolerance Indexes Analysis of Japonica Rice Cultivars at Seedling Stage and Salt Tolerance Identification

为筛选水稻耐盐品种,以10个粳稻品种为试验对象,采用对比试验的方法,分析评价1.5%NaCl水溶液对粳稻苗期各项耐盐指标的影响。耐盐指标综合分析结果表明:辽盐2号、辽粳9234、沈农9911、丰锦、辽盐糯的总体耐盐力较强;盐丰47、铁粳4号、沈农9816的总体耐盐力中等;一见钟情、松粳7号的总体耐盐力较低。

For the screening of salt tolerant varieties of rice, 10 japonica varieties were used as the test objects, using a comparative test to analyze the influence of NaCl water solution of 150 mmol/L on salt tolerance indices of rice seedlings. Comprehensive analysis of the salt tolerance index shows that the salt tolerance of Liaoyan No.2, Liaojing 9234, Shennong 9911, Fengjin, Liao yannuo is relatively stronger while that of Yanfeng 47, Tiejing 4, Shennong 9816 is of medium level and the general salt tolerance of Songjing 7 is low.
