中国西南山茶科3种植物鸟类传粉研究初报

鸟类是植物传粉的一个重要补充部分,有关鸟类传粉的研究主要集中在3个特别重要的传粉鸟类群[蜂鸟科(Trochilidae)、太阳鸟科(Nectariniidae)和吸蜜鸟科(Meliphagidae)]上[1]。相比之下,由于缺乏特化的鸟和花的协同进化关系,欧亚大陆温带和亚热带地区的鸟类传粉现象很大程度上被忽略了[2]。尽管欧洲发现了最早的传粉鸟化石,但在欧洲和亚洲喜马拉雅山以北地区几乎没有鸟类传粉的

Preliminary Study on the Birds Pollination of Three Theaceae Species in Southwest China

From 2012 to 2015, 9 species of pollination birds belonging to 7 genera of 7 families were found on three Theaceae species, i.e., Camellia oleifera Abel., Camellia riticulata Lindl. and Polyspora longicarpa (H. T. Chang) C. X. Ye, in Guiyang, Ceheng, Wangmo of Guizhou Province and in Tengchong of Yunnan Province. Southwest China has long been considered as the differentiation center and biodiversity center of birds and Theaceae in Oriental, but so many pollinating birds concentrated on plant of Theaceae visiting flowers, especially some medium-sized birds, such as Pycnotidae, Chloropseidae, Dicruridae, and Corvidae, were very rare. Further studies showed that most pollinated birds of the three plants species are short-billed birds that are occasional nectarivores and pollination syndrome exhibits on the generalized bird pollinator adaptation. Theaceae pollination system consists of insect pollination and bird pollination, the two subsystems constitute the mosaic.
