在百合花粉小孢子有丝分裂结束时，扇形细胞板形成细胞壁，形成半球形细胞。首先，新形成的生殖细胞的细胞壁与花粉粒壁的inine‐3层是不可分离的。逐渐地，靠近花粉粒壁的生殖细胞壁变厚，增厚区之间形成壁段，形成一个网状系统，使生殖细胞悬浮并与花粉粒壁分离。分离后，在intine - 2内部形成intine - 3层。生殖细胞壁和内3层由包被的囊泡、多糖颗粒和粗糙的内质网组成。
At the end of mitosis in the lily pollen microspore, the fan‐shaped cell plate gives rise to a cell wall delineating a hemispherical cell. At first, the cell wall of the newly formed generative cell and the intine‐3 layer of the pollen grain wall are inseparable. Gradually, the wall of the generative cell near the pollen grain wall becomes thicker and wall segments are formed between the thickened zones, and these make a network system by which the generative cell becomes suspended and separated from the pollen grain wall. After the separation, the intine‐3 layer is formed inside the intine 2. The generative cell wall and the intine‐3 layer are formed by coated vesicles, polysaccharide particles and rough ER.
