摘要
模拟我国出现的酸雨成分 ,设置不同的 pH值梯度 ,对大豆耐酸雨性敏感值进行了确定。为了快速、大量、准确的鉴定、筛选出强耐酸雨性的大豆品种资源 ,发现 2 .0 0为较为适宜的 pH值。并用这一方法对我国来源不同的 10 33份大豆品种资源进行了耐酸雨性鉴定 ,筛选出 1级耐酸雨性大豆品种 68份 ,其中
By using simulated acid rain with different pH values compounded according to acid rain appeared in China, sensitive pH value of soybean to acid rain tolerance was determined, and it was found that pH 2.0 was a suitable pH value for screening and identifying soybean germplasm resources rapidly, plentifully, and correctly. Using this method we evaluated 1033 accessions of soybean varieties from different places of China. Results indicated that the number of grade 1 for acid rain tolerance was 68 accessions, ...
