摘要
为了解50份引进花生品种(系)苗期耐盐性差异,筛选苗期耐盐性较好的品种(系),设置0.5%NaCl溶液和对照(ddH_(2)O)处理,测量发芽率、发芽势及幼苗期主根长、苗高、地上部鲜重、根鲜重、地上部干重和根干重,计算出相对耐盐系数和隶属函数综合值。结果表明,盐胁迫对花生幼苗期生长具有抑制作用,根据耐盐性综合评价值(D值)可将50份供试材料分为高度耐盐、耐盐、中等耐盐、敏感和高度敏感5类,其中包括1份高度耐盐材料、8份耐盐材料、13份中等耐盐材料、24份敏感材料和4份高度敏感材料。花生幼苗期干物质积累可作为评价花生品种耐盐性的主要鉴定指标。筛选出濮花9805-2、花小宝25、花育50号和远杂9847等9份苗期耐盐性强的花生种质材料,这为新疆耐盐花生品种(系)的选育提供了参考依据。
To investigate the salt-tolerance differences during the seedling stage of 50 introduced peanut varieties(lines)and screen for varieties(lines)with better salt tolerance,an experiment was conducted using 0.5%NaCl solution and ddH_(2)O(control).The study measured germination rate,germination potential,main root length,seedling height,shoot fresh mass,shoot dry mass,root fresh mass,and root dry mass.The relative salt-tolerance coefficient and a comprehensive D-value(subordinate function analysis)were calculated.The results confirmed that salt stress inhibited the growth of peanut seedlings.Based on the D-values,the 50 varieties(lines)were categorized into five clusters:highly salt tolerant,salt tolerant,moderately salt tolerant,salt sensitive,and highly salt sensitive.The test materials included one highly salt-tolerant germplasm,eight salttolerant germplasms,13 moderately salt-tolerant germplasms,24 salt-sensitive germplasms,and four highly saltsensitive germplasms.The dry matter accumulation at seedling stage was identified as a key indicator for evaluating salt tolerance of peanut varieties.Nine peanut germplasms such as'Puhua 9805-2','Huaxiaobao 25','Huayu 50',and'Yuanza 9847',were identified as highly salt-tolerant germplasms.These findings provide a valuable reference for breeding salt-tolerant peanut varieties(lines)in Xinjiang.
