中文摘要:
      利用0.15 mol/L 的NaCl 对160 个高粱核心品种(系)进行耐盐性筛选,以蒸馏水为对照,通过测定其萌发期苗长、根长、苗 鲜质量、根鲜质量、苗干质量和根干质量6 个指标,进行耐盐系数分析、隶属函数值分析及聚类分析筛选耐盐高粱种质。结果 表明:0.15 mol/L NaCl 胁迫处理下各个品种(系)的平均隶属函数值范围为0.059~0.639,其中编号为235、33、194、220 和4 这5 个品种(系)的隶属函数值较大,耐盐性好,耐盐性最差的品种为62。
英文摘要:
      Salt tolerance screening of 160 key sorghum varieties(lines) were performed using 0.15 mol/L NaCl. By measuring the seedling length, root length, fresh seedling quality, fresh root quality, dry seedling quality and dry root quality of these varieties in the germination period, the salt tolerance coefficient analysis, subordinate function value analysis and cluster analysis were used to screen the salt-tolerant sorghum germ plasms. The results showed that the average subordinate function value of each variety(line) ranged from 0.059 to 0.639, among which the numbered five varieties(lines) of 235, 33, 194, 220 and 4 have higher subordinate values and better salt tolerance values under the 0.15 mol/L NaCl stresses, and the poorest salt-tolerant variety is Number 62.
