Abstract:Definite divisions were made about the developing stages of Chinese fir seeds and about the periods in which hollow,kernel and woody seeds formed in embryo abortion The causes resulting in hollow,kernel and woody seeds were analysed in heredity,self infertility,bad climatic factors,and biochemical components in comparison between woody seeds and good seeds High ratio of woody seeds,a complex problem of cone embryonic development,was related to heredity,pollination and environment
