摘要:

对桂林唇柱苣苔的两个居群(YZ居群和DB居群)和百寿唇柱苣苔的开花动态、花粉活力和柱头可授性进行了比较研究。结果表明,桂林唇柱苣苔的两个居群花期、单花持续期存在明显差异,DB居群的花期较YZ居群晚,但花期长于后者。YZ居群的花期、单花持续期与百寿唇柱苣苔的花期、单花持续期相近。三者开花过程相似。花粉活性和柱头可授性达最大的时间、持续时间在桂林唇柱苣苔的两个居群以及百寿唇柱苣苔之间具有明显差异。

Abstract:

Floral dynamic,pollen viability and stigma receptivity of Chirita guilinensis at two sites(YZ group and DB group)and C.baishouensis were compared in this study. The results showed that the flowering period of inflorescence and anthesis of a single flower were different between DB group and YZ group,but analogical between YZ group and C.baishouensis:Flowering of YZ group and C.baishouensis took place from late February to late March,but occurred from middle March to middle April in DB group; the anthesis of a single flower in DB group was longer than others. However,a similar floral dynamic happened in DB group,YZ group and C.baishouensis. The peak time and its duration of pollen variability and stigma receptivity were distinctly different among DB group,YZ group and C.baishouensis.

Key words: Chirita guilinensis C.baishouensis floral dynamic pollination viability stigma receptivity
