In this study, the pollen morphology of all Ferula species distributed throughout the country of Turkey was studied with light and scanning electron microscopy for the first time. The aim is to identify the pollen morphological characteristics of 23 Ferula species. The pollen is radially symmetrical, isopolar and tricolporate in all examined species. Pollen grains are prolate and perprolate with the polar axis ranging from 22.28 to 40.47 µm and the equatorial axis from 13.70 to 18.73 µm. Their polar shapes are triangular, triangular to subtriangular and circular to subcircular. Several types of exine ornamentations have been observed on pollen through the use of scanning electron microscopy. The dendrogram constructed by using Average Linkage of the examined data revealed two main groups. It was determined that some pollen characteristics are more useful for classification than others. In particular, P, E, the ratio of P/E (pollen shape) and ornamentation in the polar and equatorial views are the most valuable variables for discrimination the Ferula species.

Ferula 属（伞形科）花粉的形态学

在这项研究中，首次使用光学和扫描电子显微镜研究了分布在土耳其全国的所有 Ferula 物种的花粉形态。目的是确定 23 种阿魏属植物的花粉形态特征。在所有检查的物种中，花粉呈放射状对称、等极和三孔。花粉粒呈扁长形和过扁形，极轴范围为 22.28 至 40.47 µm，赤道轴范围为 13.70 至 18.73 µm。它们的极坐标形状是三角形、三角形到亚三角形和圆形到亚圆形。通过使用扫描电子显微镜，已经在花粉上观察到了几种类型的外壁纹饰。通过使用检查数据的平均关联构建的树状图显示了两个主要组。已确定某些花粉特征比其他花粉特征对分类更有用。特别是，P、E、P/E 比（花粉形状）和极地和赤道视图中的纹饰是区分 Ferula 物种的最有价值的变量。
