摘 要: 通过对湖榕(Ficus sp.)和小叶榕(Ficus microcarpa L.)花形态结构特征的比较研究表明:湖榕和小叶榕的花果形态结构有较显著的差别。湖榕雌花的萼片数多为4片,萼片顶部都有毛,花粉位为精园形,花粉壁较薄,其结实率较低,只有0.1%;小叶榕雌花的萼片数多为3片,萼片顶部光滑无毛,花粉粒为圆形而壁较厚,其结实率较高,为29.1%。 Studies on the morphological and structure of flowers between Ficus sp. and Ficus micro-carpa L.The number of sepal pistillate flower of Fiucs sp. is almost 4, at the top of calyx of Ficussp. and there is hairs, the Pollen grain is ellipse and thin wall, the rate of fructification is 0.1 %; Butpistillate flower Ficus mircocarpa L. the number of sepal is almost 3, at the top of calyx has no hair andsleek, the pollen grain is gound shape and thick wall, the rate of fructification is 29. 1 %.
