| 摘 要： | 为了解北疆7种常用棉花品种的耐盐性,通过50、100和150mmol/L 3个NaC l浓度的胁迫处理,在棉花种子萌发阶段进行发芽势、发芽率的测定,在水培条件下对7个品种的生长势进行了比较,并采用隶属函数法进行耐盐性综合评价。根据耐盐性综合评价值得出供试7个棉花品种种子萌发阶段的耐盐性顺序为:新陆早10号新陆早13号新陆早12号新陆早17号新陆早31号新陆早26号新陆早18号;在幼苗生长阶段为:新陆早17号新陆早10号新陆早13号新陆早31号新陆早18号新陆早12号新陆早26号。由此可见,种子萌发阶段与幼苗生长阶段的耐盐性是不一致的,但新陆早10号在2个生长时期的耐盐性均表现较高,而新陆早26号则对盐害表现较为敏感。 |

| Abstract: | The salt resistance of seven cotton varieties which are widely grown in Xinjiang, China were evaluated by measuring their germination potential, germination rate of seeds and growth of the seedling under solution-cultured condition of three NaCl levels. Salt-tolerance was investigated by membership function method. The evaluation results of the seven varieties salt resistance during germination stage were in the order of XLZ 10 > XLZ 13 > XLZ 12 > XLZ17 >XLZ 31 > XLZ 26 > XLZ 18. However, the order changed to XLZ 17 > XLZ 10 > XLZ 13 > XLZ 31 > XLZ 18 > XLZ 12> XLZ 26 at the seedling stage. The result indicated that the salt-tolerance of cotton varieties are different during germination stage and seedling stage, and XLZ 10 was the most salt-resistance variety and XLZ 26 was the most sensitive variety at both developmental stages. |
