不同品种枣树叶片特性分析
Leaf characteristics of different jujube varieties
通过对不同品种枣树树冠上中下三个冠层、东西南北四个方位枣吊上着生叶片的数量、长宽进行统计分析,从总体平均值来看,树冠中层枣吊叶片数显著大于上、下层。四个方位枣吊着生叶片数量平均值之间差异不显著。树冠三层叶片之间长度、宽度平均值差异不显著。不同品种之间叶片平均长度、宽度差异显著。不同品种四个方位枣吊着生叶片长宽大部分存在显著或极显著差异。根据叶片面积聚类分析,可将枣树叶片分为大、中、小三类。
Through the statistical analysis of the number,length and width of hanging leaves in three canopy layers a nd four azimuths of East,west,south and north of different varieties of jujube trees,the total average value was analyzed,the number of hanging leaves in the middle layer was significantly higher than that in the upper and lower layers.There was no significant difference in the average number of hanging leaves among the four azimuths.There was no significan t difference in the average length and width among the three layers of leaves.The average length and width of leaves we re significantly different among different varieties.There were significant or extremely significant differences in the length and width of hanging leaf among different cultivars.According to the cluster analysis of leaf area,jujube leaves can be d ivided into three types:large,medium and small.
