对2003年在全省范围内所选的黧蒴优树进行表型分析,着重研究了其叶、果的性状。结果表明:多个角度证明了5株优势木法选黧蒴优树的方法是合理的,大部分数量指标完全超过5株优势木,体现优中选优的特点。方差分析结果表明:黧蒴优树的叶果性状无论从家系间或种源间均呈极显著差异。动态聚类分析显示黧蒴优树叶果有3种类型,第1类为重果圆叶型,有8个家系;第3类为轻果尖叶型,有90个家系;第2类介于第1、3类之间,有69个家系。
Phenotypic analysis was conducted on the selected tree species in the province in 2003, focusing on the traits of leaves and fruits. The results showed that: From many angles, it was proved that the method of selecting superior trees by five dominant trees was reasonable, most of the quantitative indicators completely exceeded five dominant trees, which reflected the superiority and superiority. Analysis of variance showed that the leaf-fruiting characters of the superior tree showed a very significant difference whether from family or provenance. The dynamic clustering analysis showed that there are three types of leaves in the fruit tree, the first one is the gingival leaves, there are 8 families; the third is the light fruit pointed leaves, there are 90 families; the second is between Between the first and third class, there are 69 pedigrees.
