| 摘 要： | 对芍药常见的 7个类型共 15个品种的花粉大小、形态、表面纹饰等特征进行了显微结构的观察和研究。结果表明:同一品种不同个体之间花粉粒外壁纹饰的细微结构是一致的,不同品种之间花粉粒形态存在一定差异;同一类型不同花色品种的花粉表面纹饰演化趋势与花色进化顺序基本一致;不同类型之间花粉纹饰与花型无相关性,花型演化顺序与其花粉纹饰的演化也不尽一致。 |

| Abstract: | Pollen morphological characteristics(including size,shape,and surface sculpture) of 15 cultivars in seven types of Paeonia lactiflora were examined under scanning electronic microscope(SEM).The results showed that the characteristics were stable in the same cultivars.There were some differences in pollen morphology among different types and varieties.The evolution trend of surface reticulate of different floral color varieties was relative to that of flower color,but there were no relationship and evolution trend correlation between pollen surface reticulate and flower types. |
