Green fluorescence was found in both pollen and pollen tubes.

结果表明:授粉后,花粉随即萌发,花粉管进人羽毛状柱头分支结构的细胞间隙,继续生长于花柱至子房顶部的引导组织的细胞间隙中,而后进入子房,在子房壁与外珠被之间的缝隙中向珠孔方向生长,花粉与花粉管均具有明显的绿色荧光。

Ovary inferior, 1(or 2)- or 4-celled, septa solid or practically absent (present only at base and apex of ovary); styles as many as sepals, alternisepalous, free, mostly short, grading into globose or subulate stigmas, spreading in fruit; stigmatic papillae hairlike; ovules as many as styles, rarely 1, apical, pendulous, anatropous.
