不同品种枣树叶片面积和叶形指数分析
Analysis of leaf area and leaf shape index of different jujube varieties
本试验以5年生的 16个不同品种枣树为试材,研究了枣叶片的叶面积和叶形指数的差异,并进行聚类分析,了解枣树叶片的特征,为分析枣树种质资源特点提供支持。试验结果表明:临县试验地不同品种枣树叶面积存在极显著或显著的差异,平均叶面积为 9.72±3.41cm2;16个品种枣树叶片的面积聚类分析表明,临县的 16个品种枣树叶片的面积聚类分析表明,当距离为 5时,可将枣树叶片分为五类,其中木枣面积最大,为 16.8cm2左右;雨珠面积最小,为 3.6cm2左右。当距离为 10时,可将枣树叶片分为大(16cm2左右)、中(6～14cm2左右)、小(3cm2左右)三类。
In this experiment,16 jujube trees of 5 years old were used to study the differences of leaf area and leaf shape index,and cluster analysis was carried out to understand the characteristics of jujube leaves,to provide support for analyzing the characteristics of jujube germplasm resources.The results showed that the leaf area of different jujube cultiv ars in Lin County,Shanxi was significantly different,the average leaf area was 9.72±3.41 cm2,the cluster analysis of l eaf area of 16 jujube cultivars in Lin County,Shanxi showed that jujube leaves could be divided into five categories whe n the distance was 5.Among them,mu jujube had the largest leaf area of about 16.8 cm2,while rain beads had the smal lest leaf area,about 3.6 cm2.When the distance is 10,jujube leaves can be divided into three types:large(about 16cm2),medium(about 6-14cm2),and small(about 3cm2).
