摘  要:
文章以月见草(Oenothera biennis L.)为研究对象,运用石蜡切片技术对其小孢子发生及雄配子发育进行研究。结果表明,月见草成熟花药有4个小孢子囊,花药壁发育为基本型。花药壁由5 ̄6层细胞构成,药室内壁宿存且于发育后期发生带状纤维加厚成为纤维层。绒毡层属腺质绒毡层。花粉母细胞减数分裂为连续型。成熟花粉2-细胞型为主,兼有少量3-细胞型。通过扫描电镜观察发现,成熟花粉粒呈三角形,花粉表面具3个萌发孔突起,花粉表面有褶皱纹饰。

摘  要:
Paraffin wax specimens of Oenothera biennis L.were used to observe microsporgenesis and the development of male game to phytes.The results showed that the anther of Oenothera biennis L.was tetrasp-orangiate.The anther wall development followed the basic type and there were 5-6 layers cells.The endothecium developed fibrous thickenings,and the tape of tapetum was glandular tapetum.Successive cytokin-esis in the microspore mother cells followed meiosis.Most pollen grains were 2-celled with a few 3-celled when mature.The matured pollen was triangle with drape veins and 3 colporates.
