金花茶是我国南方重要的木本食用油料树种，具有较高的经济价值。这种植物很少结出有活力的种子，也很少有繁殖生物学方面的研究。为了验证该地区是否存在雄性生殖障碍，grijsii、小孢子发生和雄配子发生。通过石蜡切片技术对Grijsii进行了评价。结果表明，花药壁发育属于基本型，由表皮、药室内壁、中层和绒毡层组成。绒毡层为腺型。小孢子母细胞减数分裂的胞质分裂为同时型。大部分小孢子为四面体四分体。成熟花粉为2细胞型，具3个萌发孔。2月上旬花药开裂，花粉粒脱落。结果表明，在该品种中未发现异常雄花。grijsii，表明雄配子体可育，雄性不育不是造成白穗醋栗结实率低的主要原因。grijsii。
Camellia grijsii Hamce is used as a woody edible oil tree and wellknow for its commercial value in Southern China. The plants rarely set viable seeds and have little work on the reproduction biology. In order to verify whether there was any obstacle of male reproduction in the C. grijsii, microsporgenesis and male gametogenesis in C. grijsii have been evaluated by paraffin section technique. The results are showed that the development of the anther wall belonged to a basic type and consisted of epidermis, endothecium, middle layers and tapetum. The tapetum conformed to the glandular type. Cytokinesis during meiosis of the microspore mother cell was simultaneous type. A majority of the microspores were arranged in tetrahedral tetrads. The mature pollen grains were 2-cell type and had three germ pores. Anthers were dehiscent and pollen grains shed on the early-February. Based our results, we did not find the abnormal male flower in the C. grijsii, suggesting that male gametes were fertile and male sterility was not the major cause of the low seed set in the C. grijsii.
