摘要
以20个切花多头菊品种为试材,采用统计分析方法,研究了11个茎枝数量性状的相关性和品种间差异,并采用标准化后的因子分析结果对供试品种茎枝数量性状进行评价,以期为切花多头菊的品种选择提供参考依据。结果表明:供试品种的11个数量性状指标变异系数在8.93%~26.83%,品种间茎枝性状差异主要体现在栽培时期的株高、茎粗、叶片数、花蕾大小与数量,以及采收时期切花枝的花序总长、节间长和花枝粗等性状,11个数量性状之间有极显著相关性。利用因子分析方法提取出3个因子,根据对应指标分别命名为F1长度、F2数量、F3粗度,方差解释率分别为30.51%、29.58%和19.41%。权重较高的指标为开放花头数、花枝粗,权重值分别为10.46%和10.32%。根据评价值结果,仅“爱之槟”“柠檬酒”“瑞丽”和“爱之黄”的综合评价等级为良好。
The quantitative traits of 11 stems and branches of 20 spray cut chrysanthemum varieties were collected,their correlation and difference among varieties were studied by statistical analysis,and varieties were evaluated by standardized factor analysis,in order to provide reference for variety selection of spray cut chrysanthemum.The results showed that,the variation coefficients of 11 quantitative traits were between 8.93%and 26.83%.The differences in stem and branch traits among varieties were mainly reflected in plant height,stem diameter,leaf number,bud size and number during cultivation,and inflorescence total length,internode length and cutting stem diameter during harvesting.11 quantitative traits were significantly correlated with each other.A total of three factors were extracted by factor analysis method and named as F1 length,F2 quantity and F3 thickness according to corresponding indexes,with variance interpretation rates of 30.51%,29.58%and 19.41%,respectively.The indexes with higher weight were open flower number and cutting stem diameter,with the weight values of 10.46%and 10.32%respectively.According to the evaluation results,the comprehensive evaluation grades of‘Aizhibin’‘Ningmengjiu’‘Ruili’and‘Aizhihuang’were good.
