Abstract:The flower-bud initiation of Chinese fir was studied in Nanpin, Fujian. The materials in this study were collected from five-year grafting tree in the seed orchard in 7—10 day‘s intervals beginning from summer of 1978 to spring of 1979 and repeated the collective from summer of 1979 to spring of 1980. The paraffin-microton-sectioning method was used in the study. The result are summerized as follows:It was found that male cone primodia of Chinese fir started to differentiate at the last decade of June. The microstrobilus primodia appeared to differentiate in the first ten days of August. Then the microstrobillus differentiated out the microsporophyll and microsporangium in the last decade of October. Mother-cell of microspore formed in January next year.The ovulate strobilus primodia of Chinese fir appeared to differentiate in the first ten days of August. It is two month more later than the male cone. Bract scale formed at the middle of October. The ovuliferous scale primodia differentiated at middle of December and ovule primodia differentiated right after it in the first ten days of January. The ovule formed in eary February.
