摘　　要：薜荔雌雄异株,分别形成雌、雄隐头花序.研究表明隐头花序的生长周期与榕小蜂的活动密切相关,根据榕小蜂的生活史和隐头花序生长的同步进程,参照Galil的分期标准,可将雄隐头花序生长周期分为雌前期(A期)、雌花期(B期)、间花期(C期)、雄花期(D期)和花后期(E期),雌隐头花序的生长周期仅分为雌前期(A期)、雌花期(B期)和花后期(E期).生长期不同的隐头花序可以通过外部某些特征识别和区分,这为异株型榕树以及相关媒介昆虫的研究和生产栽培提供了表述的统一尺度.Ficus pumila is dioecious and forms female and male syconia respectively.The study shows that the developmental cycle of syconia has a close relation with activities of fig wasps.According to the history of their lives and the same process of the development of syconia,and according to the phase standard of Galil,the developmental cycle of the male syconium can be divided into pre - female phase (Phase A),female phase (Phase B),interfloral phase (Phase C),interfloral phase (Phase D),postfloral phase (Phase E);the developmental cycle of female syconium can only be divided into pre - female phase (Phase A),female phase (Phase B),and postfloral phase (Phase E).Syconia at the different phase can be recognized and distinguished through their certain external features.This provides a unified standard for statement both of studies on dioecious banyans and their relative medium insects,and of production and cultivation of them.
