利用光镜(LM)和电镜(SEM)观察和研究海桑属6种植物的花粉形态.详细描述海桑属(Sonneratia L．f．)花粉形态学特征并建立种间检索表.根据观察和分析结果,将6种植物花粉分为四种类型,即A类型(Sonneratia alba，S．×hainanensis，s．×gulngai)、B类型(S．caseolaris)、C类型(S．ovata)和D类型(S．apetala).进而讨论海桑属花粉形态特征对化石花粉的鉴别指南,以及在古生态学研究领域的应用价值.

[Abstract]
The distribution of Sonneratia extends from East Africa to Indo-Malesia,northern Australia,New Guinea and the Western Pacific,and the Sonneratia vegetation comprises the main communities of coastal mangrove forests. This paper presents pollen morphological results based on LM and SEM observations for six species of the genus. Pollen wall debris obtained by the MP FastPrep120 were observed using SEM in order to examine the exine stratification. Four pollen types of the Sonneratia species can be grouped,namel...
