Nectar Addition Data

This study demonstrates the specific adaptive advantages of food deception by showing a concurrent reduction in particular male and female functions when a food reward is restored to a deceptive flower. In complex floral systems such as Cypripedium spp. where inbreeding depression is high, generalized food deception not only decreases the deleterious effects of inbreeding depression, but shows no negative consequences for attraction of pollinators and fruit set.

本研究通过证实当食源性欺骗花恢复食物奖励时，其特定的雄性与雌性功能会同步降低，揭示了食源性欺骗所具备的特异性适应优势。在近交衰退程度较高的杓兰属（Cypripedium）这类复杂花部系统中，泛化食源性欺骗传粉不仅能够缓解近交衰退带来的有害影响，同时对传粉者吸引与坐果率均无负面效应。
