| 摘 要： | 以13份茄子材料为试材,用0、30、60、90、120、150 mmol/L和180 mmol/L的盐溶液进行发芽试验,比较了不同材料的萌发期耐盐性.结果发现,低浓度盐胁迫(＜ 90 mmol/L)促进一些材料的种子萌发,而高浓度盐胁迫(＞120 mmol/L)抑制了种子的萌发；13份材料间存在明显的耐盐性差异,2份为极耐盐材料,3份为盐敏感材料,其余为中等耐盐材料；NaCl浓度120 mmol/L时为茄子耐盐萌发试验的临界浓度,为耐盐种质资源筛选提供了条件.

| Abstract: | Thirteen eggplant varieties were treated with different concentrations of NaCl(0,30,60,90,150 mmol/L and 180 mmol/L) and the salt tolerances were studied at germination stage.The results showed that the seed germination of some varieties was promoted under low concentration of NaCl(less than 90 mmol/L) and was repressed under high concentration(higher than 120 mmol/L).Salt tolerances of 13 materials were significantly different,and among them,2 cultivars were salt tolerant,3 cultivars fairly salt sensitive,... |
