摘要
利用常规石蜡切片技术观察海南本地槟榔雄花花药壁发育过程。结果表明:(1)每个花药具有4个花粉囊;花药壁由1层表皮、1层花药内壁、2层中层和1层绒毡层组成;(2)绒毡层来源一致,位置固定,花粉成熟时原位解体,属于腺质型,其细胞为双核。
The anther wall development of Areca catechu Linnaeus in Hainan was investigated with conventional paraffin sections.The result showed：（1） The anther had four chambers and the anther wall was composed of epidermis,endothecium,two middle layers and tapetum with two nucleate cells;（2） The tapetum with the same origin and fixed position degenerated in situ while the pollen was mature,so it was a glandular type
