摘要
以发芽率的盐/碱害指数为鉴定指标,在萌发期以110mmol·L-1NaCl(盐)和37.5mmol·L-1Na2CO3(碱)溶液处理100份大豆品种进行耐盐碱性鉴定,筛选出萌发初期耐盐碱的材料,为进一步研究和生产应用提供依据。结果表明:品种间耐盐碱性表现出明显的差异。同一品种耐盐和耐碱性趋势基本一致。高度耐盐碱的品种较少。筛选出高耐盐品种5个,耐盐品种21个,中度耐盐品种41个,敏感品种22个,高度敏感品种11个;高耐碱品种7个,耐碱品种16个,中度耐碱品种24个,敏感品种37个,高度敏感品种16个。
To screen soybean varieties tolerant to salt and alkaline, seeds of 100 soybean accessions were treated with 110 mmol · L^- 1 NaCl and 37.5 mmol · L^- 1 Na2CO3, then germinating at （25 ± 1 ） ℃ in sand bed of illumination incubator. The germination rate was determined on the 7th day after treating, and using germination percentage to evaluate salt or alkaline injury index. Results showed that the salt and alkaline tolerance varied significantly among varieties, and appeared to be coherent for same variety;only a small number of varieties with high salt and alkaline tolerance ;5 varieties with high salt tolerance,21 varieties with salt tolerance,41 varieties with middle salt tolerance,22 varieties with salt sensitivity, 11 varieties with high salt sensitivity ;7 varieties with high alkaline tolerance, 16 varieties with alkaline tolerance,24 varieties with middle alkaline tolerance,37 varieties with alkaline sensitivity and 16 varieties with high alkaline sensitivity.
