在室内模拟盐分条件下,采用6种浓度(0、0.6%、0.8%、1.0%、1.2%和1.4%)NaCl 溶液对14个绿豆品种种子进行胁迫萌发,通过测定其相对发芽率、相对发芽指数、质量指数、相对活力指数和耐盐适宜浓度、半致死盐浓度、致死盐浓度7项指标,综合评价供试绿豆品种种子萌发期的耐盐性。结果表明:不同绿豆品种的耐盐性存在显著差异,1.2%NaCl 胁迫能较好反映萌发期的耐盐性差异,可用于绿豆品种的耐盐性鉴定。经聚类分析,可将14个绿豆品种大致分为5类:中绿6号、中绿9号和中绿10号为高耐盐品种,冀绿9号、中绿11号和中绿14号为耐盐品种,中绿5号、中绿8号和中绿13号为中等耐盐品种,中绿2号和中绿12号为盐敏感品种,中绿1号、中绿3号和中绿4号为盐高敏感品种。
在室內模擬鹽分條件下,採用6種濃度(0、0.6%、0.8%、1.0%、1.2%和1.4%)NaCl 溶液對14箇綠豆品種種子進行脅迫萌髮,通過測定其相對髮芽率、相對髮芽指數、質量指數、相對活力指數和耐鹽適宜濃度、半緻死鹽濃度、緻死鹽濃度7項指標,綜閤評價供試綠豆品種種子萌髮期的耐鹽性。結果錶明:不同綠豆品種的耐鹽性存在顯著差異,1.2%NaCl 脅迫能較好反映萌髮期的耐鹽性差異,可用于綠豆品種的耐鹽性鑒定。經聚類分析,可將14箇綠豆品種大緻分為5類:中綠6號、中綠9號和中綠10號為高耐鹽品種,冀綠9號、中綠11號和中綠14號為耐鹽品種,中綠5號、中綠8號和中綠13號為中等耐鹽品種,中綠2號和中綠12號為鹽敏感品種,中綠1號、中綠3號和中綠4號為鹽高敏感品種。

The experiment was conducted indoors by simulating the salt stress conditions artificially.The seeds of 14 mung bean cultivars were germinated under 6 different concentrations of NaCl solutions (0, 0.6%,0.8%,1.0%,1.2%,1.4%).The relative germination rate,relative germination index,mass in-dex,relative vitality index,appropriate salt concentration,median lethal concentration and lethal concentra-tion were measured to evaluate the salt tolerance of different cultivars.The results showed that significant differences existed in different cultivars,and the suitable concentration of NaCl solution to reflect the salt re-sistance of mung bean at germination stage was 1.2%.The 14 mung bean cultivars could be classified into 5 types based on the cluster analysis.Zhonglv6,Zhonglv9 and Zhonglv10 had the highest salt tolerance;Jilv9, Zhonglv11 and Zhonglv14 had higher salt tolerance;Zhonglv5,Zhonglv8 and Zhonglv13 had moderate salt tol-erance;Zhonglv2 and Zhonglv12 were sensitive varieties to salt,and Zhonglv1,Zhonglv3 and Zhonglv4 were high sensitive varieties.
