摘    要:福建省东北部5个野生爱玉种群的花序分期、花数统计和套袋实验结果表明:爱玉花序具多型性,雌花序中有雌花4 405~7 143朵,雄花序中有瘿花4 856~8 864朵,花数相差悬殊并与花序外形大小呈正相关;瘿花已不能结实,在生理功能上与雌花完全分离,实为专供小蜂生长的中性花;雌花序发育无C,D期,由B期直接进入E期,人工授粉可获96.36%的结实率.

关 键 词:爱玉  隐头花序  薜荔榕小蜂  生物学特性

Abstract:Ficus pumila var.awkeotsang belongs to climbing bush in the Moraceae,which in recent years is artificially planted in Fujian.The study of syconium classified periods,statistics of the number of its flowers and bagging experiment of five wild  F.pumila var. awkeotsang in the northeast of Fujian show that syconia of  F.pumila var.awkeotsang have many types,that is,there are 4 405~7 143 female flowers in the female syconium and 4 856~8 864 gall flowers in the male syconium; great difference of the flower number is identical to the outside size of the syconium and the gall flower can not bear fruit,which is completely separated with the female flower in the physical function and whose fruit is a neutral flower specially for the growth of the Wiebesia pumilae;the female syconium growth has no phase C and D,phase B directly enters phase E,and the artificial pollination can get 96.36% of the fruit-bearing rate.The results provide reference data for the basic study and cultivation.
Keywords:Ficus pumila var  awkeotsang  syconium  Wiebesia pumilae  biological features
