摘要
选取了7个与月季扦插效果密切相关的形态指标,用主成分分析法、隶属函数法和聚类分析,对18个月季品种的扦插效果进行综合评价.结果表明,按扦插效果可分为3个等级,即优秀、一般和较差,每个等级间都存在显著差异;11个月季品种的扦插效果优秀,插穗成活率与扦插苗品质较高.
This paper selected the seven indexes which were closely related to cutting effect of Chinese rose,the cutting effect of 18 Chinese rose varieties was evaluated by the methods of principal component analysis,membership function method,hierarchical cluster analysis. The results showed that the cutting effect of 18 Chinese rose varieties was divided into three grades of excellent,general and poor. There were significant differences between each grade. The excellent cutting effect was included 11 Chinese rose varieties,which survival rate and the quality of cuttings were higher.
