Cluster Analysis of Characteristics of Different Sweet Cherry Varieties

甜樱桃不同品种特性的聚类分析（英文）

In order to compare the characteristics of different varieties of sweet cherry and to formulate corresponding pruning scheme, hierarchical cluster analysis was conducted for the 14 sweet cherry varieties that were mainly planted in Shanxi Province. The results showed that the 14 varieties of sweet cherry could be divided into two types, Hongmanao and Rainier. Fruit setting rate, branching rate, medium fruit shoot proportion, spur proportion and yield per plant were significantly different between these two types of sweet cherry. The key points of pruning management, to improve the yield of Rainier type, were to increase the fruit setting rate and spur proportion, and to control properly the long and medium fruit shoot proportion.

为探明甜樱桃不同品种特性并有针对性的制定修剪方案,采用系统聚类分析法,研究山西省种植的14个甜樱桃品种的枝类组成。研究结果表明,供研究的14个甜樱桃品种,可以区分为以‘红玛瑙'和‘雷尼尔'为代表的2种类型;不同类型之间的坐果率、成枝率、中果枝比例、短果枝比例和单株产量差异均达到显著水平。为提高‘雷尼尔'品种类型的产量,树体整形修剪管理的重点,在于提高坐果率、短果枝比例,并适当控制中、长果枝比例。
