摘　　要：目的:进一步完善芸香科(Rutateae)5种保健植物茵芋(Skimmia reevesiana Fort)、黄皮(Clausena lansium(Lour.)Skeels)、九里香(Murraya exotica Linn.)、柠檬(Citrus limon(Linn.)Burm.f)、代代酸橙(Citrus aurantium Linn.cv.‘Daidai’)花粉形态学数据,为品种分类和系统进化研究提供孢粉学资料。方法:采用一致的方法收集5种保健植物材料花粉,使用FAA固定液固定,冷冻干燥法处理,在扫描电子显微镜下观察花粉的形态。结果:芸香科5种保健植物茵芋、九里香、黄皮、柠檬、代代酸橙均为单粒花粉,形态特征明显,若干花粉形态指标和外壁纹饰指标存在显著差异,可作为亚科种属分类鉴定的重要孢粉学指标。Objective:The pollen morphology of five health plants in Rutaceae,such as kimmia reevesiana Fort,Clausena lansium(Lour.)Skeels,Murraya exotica Linn.,Citrus limon(L.)Burm.F and Citrus aurantium L.cv.‘Daidai’was further improved to provide palynological data for species classification and phylogenetic study.Methods:The pollen of five kinds of health plant materials was collected by the same method,fixed with FAA fixative,and dried by freeze-drying instrument.The morphological indexes of the five kinds of pollen were observed under scanning electron microscope.Results:The five health plants of Rutaceae,such as kimmia reevesiana Fort,Clausena lansium(Lour.)Skeels,Murraya exotica Linn.,Citrus limon(L.)and Citrus aurantium L.cv.‘Daidai’,are all single pollen with obvious morphological characteristics.There are significant differences in pollen morphological indexes and exine ornamentation indexes among subfamilies,genera and varieties,which can be used as important palynological indexes for the classification and identification of subfamilies and genera.
