| 摘 要： | 根据植物花粉性状的稳定性和遗传保守性,对供试的梨属植物4个种的代表品种以及苹果梨的花粉形态进行观察研究,并采用数量化的分析方法,对花粉形态7个性状进行了聚类分析。结果表明:梨属植物花粉形态有其共同特征,而不同种和品种间在花粉粒的形状、大小和纹饰等方面存在着程度不同的差异;根据花粉数量性状进行的系统聚类分析,能将起源于欧洲的西洋梨与起源于中国的3个种明显区分开;从花粉粒大小及纹饰特征来看,苹果梨性状独特,有些性状与东方梨相似,有些性状又与西洋梨相近。

| Abstract: | Four representative cultivars of Pyrus spp.and pollen morphology of apple-pear were studied according to stability & hereditary conservation of pollen characters of plant.Adopted numerical taxonomy method,7 characters of pollen morphology was conducted cluster analysis.Result shows that there were same characteristic in pollen form of Pyrus,but there were some differences in pollen grain's shape,size and lines of different species and cultivars;based on the cluster analysis with pollen quantity characterist... |
