Honeybees play a significant role in the plant-pollinator interactions of many flowering plants. The ecological and evolutionary consequences of plant-pollinator interactions vary by geographic region, and the effects of honeybees on the reproduction of toxic plants have not been well studied. We measured the florescence of toxic plants, the flower-visiting behaviour of honeybees and the effects of pollination on the fertility, weight and moisture content of seeds. The effects of climatic factors on the number of flowers, and the spatial and temporal variation in pollinator visits were evaluated, and the effects of pollinator visits on seed quality were evaluated. Flower visitors were diverse, climatic factors had a great impact on spatio-temporal flowering variation and the number of bee visits was strongly correlated with the spatio-temporal variation in the number of flowers. Honeybees strongly increase the fullness and weight of seeds. Our study demonstrated a good ecological fit between the spatio-temporal variation in the flowering of toxic plants and the general validity of honeybee pollination syndrome in the south of Hengduan Mountains in East Asia. A linear relationship between honeybee visitation and plant reproduction can benefit the stabilization of plant reproduction.
蜜蜂在许多开花植物的植物-传粉者相互作用中发挥着重要作用。植物-传粉者相互作用的生态和进化后果因地理区域而异，而蜜蜂对有毒植物繁殖的影响尚未得到充分研究。我们测量了有毒植物的花期、蜜蜂的访花行为以及授粉对种子育性、重量和水分含量的影响。评估了气候因素对花朵数量的影响以及传粉者访花的时空变化，并评估了传粉者访花对种子质量的影响。访花者种类多样，气候因素对开花的时空变化有很大影响，蜜蜂访花次数与花朵数量的时空变化密切相关。蜜蜂显著增加了种子的饱满度和重量。我们的研究表明，东亚横断山脉南部有毒植物开花的时空变化与蜜蜂授粉综合征的普遍有效性之间具有良好的生态适应性。蜜蜂访花与植物繁殖之间的线性关系有利于植物繁殖的稳定。
