福建柏开花与结实物候期的研究

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。

Study on Phenology of Flower and Cone of Fokienia hodginsii

Fokienia hodginsii has twice florescence a year:spring florescence from April to May,the cone is ripe in October of the same year,the seeds haven't viability;autumn florescence is main florescence from September to October,the cone is ripe in October of next year,the seed has viability.Biology and phenology characters of flower and cone are closely link to geography and climate factors including place,kind,altitude,temperature,etc.of natural distribution area.Variations of florescence,mature period or cone and harvesting period of seed is at mountain more early than at middle mountain,at middle mountain more early than at hill,at high altitude area more early than at low altitude area.Variations of germination percentage is mountain>middle mountain>hill.
