运用花粉剥离新技术，剥开梨的花粉粒，用扫描电镜观察梨花粉粒的不同层次的表面和断面结构特征。梨树花粉表面雕纹多属长条纹饰，亦有网状纹等其他纹饰。萌发孔为三孔沟或四孔沟的沟孔复合结构。外壁结构层次分覆盖层、柱状层（基粒棒层）、基足层。内壁表面有微孔和细微结构，由内壁包裹的花粉原生质体和内室表面上的三个花粉管原始体。 Pear pollen grains were peeled off using a new technique of pollen stripping, and the surface and cross-sectional structures of pear pollen grains were observed by scanning electron microscopy. Pear pollen surface is mostly long lines of ornamentation, there are other ornamentation mesh lines. Germination holes for the three holes ditch or four ditch ditch composite structure. Outer wall structure level sub-cover, columnar layer (basement layer), basement layer. The inner wall surface has micropores and fine structure, the pollen protoplasts wrapped by the inner wall and the three pollen tube primitives on the inner chamber surface.
