猕猴桃是雌雄异株植物,进行种间杂交和授粉试验时,常常要采集和贮藏花粉。中华猕猴桃的花粉粒近球形,极面观为三裂圆形,大小17.4—24.4微米,具三孔沟,花粉壁厚度1.5—2微米,两层,有时层次模糊。花粉发芽试验培养基用10%的蔗糖+1.0%琼脂+0.001%硼砂。在室温23—26℃的条件下,1小时后陆续发芽。新鲜花粉发芽率一般60—75%,新鲜花粉在室温条件下,贮存在于燥器内,25天后几乎 Kiwifruit is a dioecious plant, and it is often necessary to harvest and store the pollen when interspecific hybridization and pollination are carried out. Chinese kiwifruit pollen nearly spherical, polar view of the three-split circular, the size of 17.4-24.4 microns, with three-hole ditch, pollen wall thickness of 1.5-2 microns, two, and sometimes fuzzy. Pollen germination test medium with 10% sucrose + 1.0% agar + 0.001% borax. Under the conditions of room temperature 23-26 ℃, 1 hour after germination. Fresh pollen germination rate of 60-75%, fresh pollen at room temperature, stored in a desiccator, almost 25 days after almost
