摘要: 在种子萌发期间,采用0. 5、1. 0、2. 0、3. 0、5. 0、7. 0、9. 0 g/L 等7 个不同浓度的NaCl 溶液处理,研究3 个不同菜豆品种对NaCl 盐胁迫的响应。结果表明:高浓度盐溶液处理降低了3 个菜豆品种的发芽率、发芽势、发芽指数、活力指数以及幼苗的根长、芽长、侧根数、鲜重、SOD活性,提高了MDA含量,低浓度处理对种子萌发指标、幼苗生长指标以及生理指标等的影响则与NaCl 浓度以及菜豆品种有关。隶属函数法综合评价结果表明:3个菜豆品种的耐盐能力依次为红花白荚菜豆>西杂二号(宽)菜豆>西杂二号菜豆。

Abstract: During seed germination,seven different concentrations of NaCl solution(0. 5,1. 0,2. 0,3. 0,5. 0,7. 0,9. 0 g/L)were used to study the response of three different varieties of kidney beans under NaCl stress. All the three varieties of kidney beans showed the trend that high concentrations of NaCl solution decreased seed germination rate,germination potential,germination index,vigor index,root length,bud length,lateral root number,fresh weight,SOD activity while increased the MDA content of seedlings. However,the effects of low concentrations on seed germination index, seedling growth index and physiological index were related to the concentration of NaCl and the variety of kidney bean. The results of comprehensive evaluation of membership function showed that the salt tolerance of the three varieties was in the order: safflower white kidney bean > Xiza 2 (wide) kidney bean > Xiza 2 kidney bean.

Key words: kidney bean, seed germination, seedling growth, membership function, salt tolerance
