近年来,果树分类学家开始应用扫描电子显微镜,深入研究果树植物的花粉形态和解决果树分类及品种鉴定工作中的某些问题。Maas观察了草莓,葡萄和其他几种小浆果的花粉,看到这些果树花粉在大小,表面雕纹和微孔结构上都有很大差异。Westwo-od观察了梨属植物中不同种的花粉,并根据花粉粒的大小,形状及花粉壁上明显的脊、 In recent years, fruit tree taxonomists began to use scanning electron microscopy, in-depth study of the pollen morphology of fruit trees and fruit trees to resolve the classification and identification of some of the problems in the work. Maas looked at the pollen of strawberries, grapes and several other small berries and found that these fruit pollen vary greatly in size, surface carving, and micropore structure. Westwo-od observes the different types of pollen in the genus Pyrus, and according to the size and shape of the pollen grains and the obvious ridges on the pollen wall,
