摘　　要：福建柏1年2次花期,春花期4～5月,果期当年10月,种子无生活力;秋花期9～10月,果期翌年10月,种子有生活力,有效花期在秋季。开花结实的生物学及物候学特性与适生区的地点、地类、海拔、温度等地理气候因子紧密相关,总体变异规律:秋花期、球果成熟期、种子散落期山区比半山区早,半山区比丘陵区早,高海拔地区比低海拔地区早,发芽率山区>半山区>丘陵区。Fokienia hodginsii develops flowers twice a year: spring florescence from April to May, the with cone maturation in October of the same year, but the seeds are not viable. Flowers develop again in autumn with cone maturation with viable seeds occuring the following years.Biology and phenology characteristics of flowers and cones are closely link to geography and climate factors within the natural habitat of (F. hodginsii). Variations of florescence and maturation period of the cone and harvesting period of seed is determined by altltude with higher elevations maturing first. Elevation also effects germination percentages.
