2022 年 9 月nents and
behavior of pollinating insects were studied. The results showed that there was no automatic selfing and apomictic
reproduction in C. floribundum, and the formation of seeds depended on pollinators. Its natural seed setting rate was much
lower than that of artificial pollination, and there were serious pollination restrictions. Apis cerana was an effective
pollinator for C. floribundum, but it could not get reward from the plants. During pollination, the pollinium was taken out
together with the cap. Through the behavioral experiments of insects, it was found that the odor of C. floribundum played a
key role in attracting pollinators, while the color had no significant attractive effect on A. cerana. The main volatile
components of flowers were aldehydes and alcohols, and there was almost no change in type and amount in a day for the
volatile components. Only the change in linalool content was related to the frequency of pollinating insects. This study could
provide a certain basis for wild protection and hybrid breeding of orchids.
Key words: Cymbidium floribundum; breeding system; honeybee; pollination biology
