| 摘 要： | 首次报道中国稠李属花粉形态研究,结果表明:花粉粒形态、大小和外壁纹饰可作为划分种的依据。由此可区分为:花粉粒32.0×25.5μm、条纹细弯、穿孔明显的是亚洲稠李(P.asiatica Kom.);花粉粒37.5×17.7μm、体积大、穿孔多的是光叶亚洲稠李(var.subglabra Y.L.Hanet C.Y.Yang var.nov.);花粉粒32.0×24.4μm、条纹细直、穿孔少量的是欧洲稠李(P.aviummill.);花粉粒21.0×22.1μm、条纹宽、直、穿孔不明显,即北京稠李(P.beijingensis Y.L.Hanet C.Y.Yang sp.nov.),(新种已另文发表)。 |

| Abstract: | This paper is the first report on the morphological characteristics of pollen of three species of Padus in China and the results showed that the species of Padus can be classified on the basis of the morphology, size, and exine sculpture of pollen.P.asiatica Kom.has pollen grains with size 32.0×25.5μm, finely curved strialion, and marked perforation and var.subglabra has pollen grains with relatively large size 37.5×17.7μm and more per-foration.The species with pollen grains size 32.0×24.4μm, finely strainght striation, and less perforation is P.avium Mill.and the species with pollen grains size 21.0×22.1μm, widely straight striation, and indistinctive perforation is P.beijingensis Y.L.Han et C.Y.Yang sp.nov. |
