Citrus is one of the most important economic fruit species worldwide. Pollen properties are one of the hereditary characteristics used in the identification of plants. In this study carried out in different Citrus genera and species, pollen size and morphology were investigated by scanning electron microscope (SEM). According to this, pollen shape is divided into two groups as oblate and suboblate. Colpi and pore are located on the pollen surface. The statistical difference occurred among the ten Citrus genotypes in terms of mean pollen length, width, length/width ratio and measurements of surface structures. Lemon varieties have the longest pollen, in general. Poncirus trifoliate was separated from the others by taking place alone.

柑橘是全球最重要的经济水果品种之一。花粉特性是用于鉴定植物的遗传特征之一。在这项对不同柑橘属和种进行的研究中，通过扫描电子显微镜（SEM）研究了花粉大小和形态。据此，花粉形状分为扁圆形和近扁圆形两类。Colpi和孔位于花粉表面。十种柑橘基因型在平均花粉长度、宽度、长/宽比和表面结构测量方面存在统计学差异。一般来说，柠檬品种的花粉最长。Poncirus trifoliate通过单独发生与其他人分开。
