利用普通光学显微镜和扫描电镜技术对黄金树花器官的发生及发育过程进行了观察。结果显示:(1)黄金树花器官的形态发生及发育过程集中于3月下旬—5月上旬;(2)花原基分化形成花的整个过程符合一般的分化顺序:花萼原基—花冠原基—雄蕊原基—雌蕊原基,且各原基在分化顺序上存在交叉;(3)花药及胚珠的发育与花器官的形态发生之间有明显的连续性,当花蕾直径为3.0mm左右时花粉母细胞及完整的花粉囊壁形成,直径达到3.5mm左右时胚珠中出现孢原细胞的分化,它直接起大孢子母细胞的功能。 The occurrence and development of floral organs of P. arborvitae were observed using ordinary light microscope and scanning electron microscopy. The results showed that: (1) Morphogenesis and development of floral organs of Grifola fruticosa were concentrated in the late March to early May; (2) The whole process of flower primordium differentiation was in accordance with the general differentiation order: calyx primordium - Basal-stamen primordium-pistil primordia, and the primordial bases cross each other in order of differentiation. (3) There is a clear continuity between the development of anther and ovule and the morphogenesis of floral organs. When the flower bud diameter is about 3.0mm When the pollen mother cells and the integrity of the formation of pollen wall, when the diameter of about 3.5mm ovules occur in the differentiation of sporogenous cells, it directly from the megaspore mother cell function.
