摘要
采用扫描电子显微镜,比较了13个牡丹品种的花粉形状、大小、外壁纹饰及萌发沟等。采用离体培养法,分析比较了13个品种的花粉萌发率。结果表明:13个牡丹品种的花粉有较明显的多样性,赤道面观有近球形和长球形,极面观有三裂圆形和三裂三角形。花粉均具三拟孔沟,外壁纹饰形态多样,有小穴状、穴状、网状、穴网状。‘百花娇’花粉萌发率最高(67.70%),‘洛阳红’萌发率最差(19.43%)。
By using scanning electron microscopy, we observed the pollen morphology of 13 peony varieties, including the germi- nation of pollen shape, pattern and size, and external organs, and studied the 13 peony pollen germination rate by in vitro culture method. The 13 varieties of peony pollen were more obvious, and the equator plane view was divided into nearly spherical and long ball. Polar view-crack was divided into three round and three crack triangle, the germination organ with three intended hole groove, external wall decoration patterns and diverse, which was divided into small foveolate, foveo- late, reticulate, and foveolate-reticulate. Highest germination rate under the same conditions is ＇ baihuajiao＇ of 67.7%, and the worst is ＇ luoyanghong＇ of 19.43%.
