| 摘 要： | 选用102份大麦品种,采取双重对照法,考查了处理和对照的株高、主穗长、穗下节间长、单株穗数、主穗排数、单株粒重、单株粒数、成活率、超氧化物歧化酶含量和丙二醛含量等10个性状。以各单项指标的耐盐指数作为衡量其单项耐盐能力大小的指标,应用典型相关分析,对大麦在一定盐分浓度胁迫下其主要性状表现进行了研究。不同因子指标集团的典型相关分析表明:成活率、株高和单株粒重这3个指标可作为耐盐性评价的一级指标。超氧化物歧化酶、丙二醛、穗下节间长、主穗长、主穗排数和单株粒数可作为耐盐性评价的二级指标。单株穗数在3个因素组都没有较大的负荷量,可不考虑作为耐盐性评价的指标。

| Abstract: | In this study,the salt resistances of 102 barley varieties under salt stress were analyzed by using canonical correlation analysis based on the salt resistant indexes of 10 traits,including plant height(PH),spike length(SL),the top 1st internode length(TFIL),spikes per plant(SPP),rows per spike(RPS),grain weight per plant(GWPP),grains per plant(GPP),survival rate(SR),superoxide dismutase(SOD) and malondialdehyde(MDA).The canonical correlation analysis indicated that the relationships among the three groups(... |
