| 摘 要： | 通过光学显微镜和扫描电镜观察了6种前胡属Peucedanum L．植物的花粉形态，其中三种为国内首次报道，研究结果表明：该属花粉为三棱长球形，三孔沟，边孔，外壁两层，层次分明．根据花粉形态主要可归为：矩形型和赤道收缩形型二个类型．光镜下表面为细网状，网状，清楚或模糊，扫描观察为条-网状，有少数疣状饰物．结合前人研究结果，总结出10种前胡属的花粉类型，萌发孔的特征，外壁纹饰等，支持了关于前胡属在伞形科中是一个较自然和较进化的类群的观点．通过比较认为前胡属多小苞片组为该属较为原始的类群；近亮舌床组在该属中较为进化，刺尖前胡组为过渡类群；同时认为前胡属是一个处于活跃分化期的类型．

| Abstract: | In this paper,pollen morphology of 6 species of the genus Peucedanum was investigated.Pollen grains of all the species were examined by LM and SEM.Among them 3 species were palynologically reported here for the first time.The study showed that pollen grains of Peucedanum were in various shapes.Their frame work was trigonal in solid form Ktricolporate,pleurot reme and exine 2-lauered.The statification of exine was clear.According to the characteristics of the pollen grains in Peucedanum,it may be divided int... |
