对6000余份高粱种质资源在发芽期和苗期进行了耐盐性鉴定。以2.5%NaCl溶液作发芽试验,按盐害百分率分级,1级品种335份,2级639份,3级982份,分别占参试材料份数的5.1%、9.7%和14.8%。在滨海盐土地区进行苗期鉴定,1、2级品种有3份,3级119份。两个时期都是3级以内的品种有21份。
The salt tolerance of more than 6,000 sorghum germplasm resources during germination and seedling stage was evaluated. The germination tests were conducted in 2.5% NaCl solution. According to the percentage of salt damage, 335 varieties were Grade 1, 639 were Grade 2 and 982 were Grade 3, accounting for 5.1%, 9.7% and 14.8% of the tested materials respectively. In the coastal saline soil seedling identification, 1,2 varieties have 3, 119 119. In both periods, there are 21 species within 3 levels.
