中文摘要：

为了深入研究华木莲（Sinomanglietia glauca）的传粉生物学机制，以木莲属巴东木莲（Manglietia patungensis）和木兰属广玉兰（Magnolia grandifloFa）为参照，对华木莲的单花特征、开花动态、访花昆虫及访花行为进行了观察。结果表明：华木莲的单花性状和访花昆虫与巴东木莲和广玉兰有明显区别。开花后，华木莲内层2轮花被又重新闭合，仅在花被片下部存在孔隙。华木莲访花昆虫为缨翅目蓟马和露尾甲科昆虫。

英文摘要：

We observed the single flower characteristics, floral dynamic, visiting insects and flowering behavior of Sinomanglietia glauca, Manglietia patungensis and Magnolia grandiflora for pollination. The two inner perianths in S. glauca were reclosed after flowering, only the pores were present in the lower part of the tepals, and the visiting insects were thrips of Thysanoptera and beetles of Nitidulidae.
