通过传粉媒介观察和手工授粉实验，在其自然栖息地对濒临灭绝的兰花杓兰进行授粉生物学研究。观察坐果情况：人工异花授粉，100%；人工自花授粉，100%；传粉媒介排除，0%；和去雄花，0%。这些结果表明，该物种虽然是自交亲和的，但既不是自花受精也不是无子受精。开放授粉花朵的坐果率为 14.9%，这表明研究群体受到传粉媒介的限制。 C.无花蜜的花。 日本熊蜂专门由两种熊蜂（Bombus ardensandB. diversus diversus）的蜂王来访并授粉。 C. 很可能是无花蜜的花。 japonicumat通过通用的食物欺骗系统吸引传粉者。
Pollination biology studies of the endangered orchidCypripedium japonicumwere conducted in its natural habitat using pollinator observation and hand‐pollination experiments. The observed fruit set was as follows: artificial outcross‐pollinated, 100%; artificial self‐pollinated, 100%; pollinator‐excluded, 0%; and emasculated flowers, 0%. These results show that this species, although self‐compatible, is neither autogamous nor agamospermous. The fruit set for open‐pollinated flowers was 14.9%, which suggests that the study population was subject to pollinator limitation. The nectarless flowers ofC. japonicumwere exclusively visited and pollinated by the queens of two bumblebee species (Bombus ardensandB. diversus diversus). It is probable that the nectarless flowers ofC. japonicumattract pollinators through a generalized food deceptive system.
