摘要: 对大百合×百合属间杂交授粉后花粉管的行为进行了观察, 结果表明百合的花粉能在大百合的柱头上萌发, 伸入中央花柱道, 到达花柱基部, 进入子房。杂交后, 花粉萌发与花粉管的伸长速度相对于自交滞后, 个别花粉管出现末端分叉、膨大或变细或中间部分折叠, 花粉管内胼胝质不规则的大量沉积等现象。

Abstract: The pollen tube behavior in the style following the hybridization between Cardiocrinum giganteum and Lilium were observed by means of fluorescence microscopy. The results indicated that the pollen of Lilium can germinated on the stigma of C. gaganteum and pollen tubes can reach the basal part of the style and finally arrive at the ovule in ovary, meanwhile, the result also showed that the speed of the pollen germination and pollen tube elongation following hybridization were much slower than that following intraspecificpollination, several abnormalities of pollen tubes were observed including pollen tubes with branching off, swollen or pointed tips, or superposition in the middle parts lots of callose depositiing at irregular distances, parts of pollen tubes became wave2liked at the middle or basal part of the style, which finally lead to the
failure to arrive at the ovary.
