本文主要阐述金钱松传粉、受精和胚胎发育各期进行的时间和特点。4月上、中旬花粉成熟为传粉期。5月花粉在珠心上萌发,2精核移入花粉管,同时颈卵器形成和卵细胞逐渐成熟。6月受精,受精卵形成新细胞质,继而发育成为4、8、16细胞至球形原胚,胚柄延长。7月胚体增大,根端先分化,苗端后分化。10月胚成熟。金钱松为简单多胚,原胚为松型原胚。 This paper mainly elaborates the time and characteristics of the process of pollination, fertilization and embryonic development of Pinus thunbergii. April, mid pollen mature pollination. May pollen germination on the heart of the beads, 2 into the pollen tube, while the formation of archegonium and egg cells gradually mature. June fertilization, fertilized eggs to form a new cytoplasm, and then developed into 4,8,16 cells to spherical proembryo, prolonged embryos. July embryoid body increased, the first root differentiation, seedling differentiation. October embryos mature. Money pine is a simple multi-embryo, the original embryo pine original embryo.
