摘    要:通过扫描电镜观察了中国悬钩子属7组23亚组共103个种的花粉形态。本属花粉为圆球形、近 球形、长球形和超长球形,少数为菱形和六边形,具三孔沟,大小多为16.0~38.Oμm×12.0~30.0μm,外壁纹饰可分为皱波型、条纹型、脑纹型和穿孔网型等类型,进而可分为皱波-近光滑状、皱波-条纹状、皱波-穿孔状、条纹状、条纹-穿孔状、条纹-网状、脑纹状、脑纹-穿孔状、穿孔状、穿孔-网状及网状等11个亚型。分析结果认为,悬钩子属的花粉形态特征对该属种的区分有一定的参考价值,但要合理地阐释其系统发育意义,仍需积累更多的信息。

Abstract: Pollen morphology of 103 species belonging to twenty-three subsections of seven sections of Rubus L. was examined with SEM. The pollen grains are usually 3-colporate, spheroidal, sub- spheroidal, prolate and perprolate, though occasionally rhombic and hexagonal, 16.0~38.0 μm × 12.0~30.0 μum in size. The exine ornamentation can be divided into rugulate, striate, cerebroid and perforate-reticulate types, which include 11 subtypes: rugulate-subpsilate, rugulate-striate, rug- ulate-perforate, striate, striate-perforate, striate-reticulate, cerebroid, cerebroid-perforate, perforate, perforate-reticulate and reticulate. The pollen morphology is of some significance for a better classification of the genus Rubus, but seems to be of little help for a better understanding of thephylogeny of the genus.
