摘要:
应用扫描电镜对蜡梅3个品种群共21个品种的花粉粒形态特征进行了观察和比较,对观测结果进行了主成分分析与聚类分析。结果表明:蜡梅花粉粒为中等大小,近扁球形至圆球形;蜡梅花粉外壁纹饰可分为蠕虫状和拟蠕虫状两个类型;蜡梅品种间花粉形态比较类似,但在纹饰细微特征、花粉粒大小、萌发沟长宽度等方面存在一定差异,可作为区分品种的辅助依据;花粉形态聚类分析结果与传统形态分类结果存在差异,花粉形态与内被片和中被片颜色并无直接关联。
Abstract:
Pollen grain characteristics of 21 Chimonanthus praecox cultivars in 3 groups were examined and compared under scanning electron microscope (SEM), and principal component analysis and cluster analysis were conducted based on observation results. The results showed that the pollen grain was in midsize, and in suboblate to globular shape. The exine ornamentation could be divided into two types: helminthoid and quasihelminthoid. Pollen morphology of the cultivars was quite similar, but there were certain differences in details of ornamentation, size of pollen grains, length and width of colpus, so they could provide ancillary evidence for cultivar identification. There was difference between the result of cluster analysis for pollen morphology and that of traditional morphological classification, there was no direct relationship between pollen morphology and color of inner or medium petals.
