摘    要:通过光学显微镜和扫描电镜观察,描述了9种木兰科植物(华木莲Sinomanglietia glauca,巴东木莲Manglietia patungensis,白玉兰 Magnolia denudata,望春玉兰 Magnolia biondii,天目木兰 Magnolia amoena,美毛含笑Michelia caloptila,乐昌含笑Michelia chapensis,深山含笑Michelia maudiae,宝华玉兰Magnolia zenii)的花粉形态特征。观察结果表明。9种木兰科植物花粉的形状、萌发孔类型基本一致。但大小及外壁纹饰存在差异,甚至同种植物的不同居群亦如此。因此,木兰科植物的花粉形态特征有一定程度的分类学价值,但引用时须慎重,并与其他资料相结合。图1表1参8

Pollen morphology of 9 species from Magnoliaceae
Abstract:The pollen morphology characteristics of 9 species of Magnoliaceae(Sinomanglietia glauca, Manlietia patungensis, Magnolia denudata, Magnolia biondii, Magnolia amoena, Michelia caloptila, Michelia chapensis, Michelia maudiae, Magnolia zenii)were observed by both optical microscope and scanning electron microscope(SEM),the result showed that the shape and germination aperture of 9 speices are similar,but their size and exine sculpture are different,and so are the different population of one species.Therefore,pollen morphology can be applied for taxonomy of Magnoliaceae to some extent,and it is important to adopt these evidence carefully combined with other evidence.Ch,1 fig.1 tab.8 ref.]
