中国红树植物花粉形态

POLLEN MORPHOLOGY OF THE MANGROVE PLANTS IN CHINA

红树林是热带海岸的特殊植被类型。红树植物花粉已被证实加入海泥沉积,因此,可作为海滨、浅海相的直接标志。本文对分布于我国的红树植物22科29属40种以及寄生在红树植物上的桑寄生科植物3属3种进行光学显微镜及扫描电子显微镜的观察,以期为海洋地质勘探提供参考依据。

Mangrove is a special type of vegetation along the tropical and subtropical seacoast. It was proved that the pollen grains of mangrove plants join the sedi-mant of the seabed. They are regarded as seaboard and neritic indicia in identification of stratum. Chinese mangrove comprises 41 species belonging to 30 genera and 23 families, which distribute in Hainan ( 40 spp. ) , Guangdong ( 23 spp. ) , Guangxi ( 12 spp. ) , Fujian ( 7 spp. ) and Taiwan ( 16 spp. ) . They belong to the eastern formation. The pollen grains of 40 species of Chinese mangrove plants and of 3 species of Loranthaceae in mangrove were examined under light microscope and scanning electron microscope.The pollen grains of Rhizophoraceae, Sonneratlaceae and some other species such as Aegiceras corniculatum, Avicenna marina, Acanthus ebracteatus, Acostichum aursum etc. provide an improtant function in identification of stratum.
