月季品种扦插生根能力综合量化评价
Comprehensive Quantitative Evaluation of Cutting Rooting Ability of Rosa chinensis Varieties
摘要
Abstract
To comprehensively evaluate the rooting ability of different types and varieties of rose,and select the varieties with a strong rooting ability to provide reference for the future production and breeding of rose varieties,59 rose varieties introduced and cultivated in Kunming,Yunnan Province,China were used as experimental materials,the root morphological indexes of rose cuttings were measured by WinRHIZO root analysis system,and the rooting ability of each rose variety was comprehensively quantitatively evaluated by principal component analysis and membership function analysis.The distribution of the root indexes of rose cuttings basically conformed to the normal distribution,except for the number of branches,the difference of the root indexes was small.Principal component analysis transformed 7 single indicators into 2 independent factors,with a cumulative contribution rate of 89.53%.Through membership function analysis,it was found that there were 23 varieties with a comprehensive score≥0.40,accounting for 38.98%.In this study,10 rose varieties with the strongest rooting ability were selected,including'Angela','Rouge Royal','Red Apple rose','Clg White Eden Rose','Highgrove','Pink Flamingo','Fensemenghuan','New Imagine','Billet Doux'and'Crown Princess Margareta',which can be used as a breed for large-scale production and as a parent for genetic improvement.关键词
