研究了授粉对飞蛾授粉兰花 Platanthera bifolia 花香成分和产生的影响。授粉后两天和五天检测到气味产生显着减少。 7 天后，与对照植物相比，受粉植物枯萎花朵的比例更高。主成分分析（PCA）显示授粉如何减少气味的产生。所有气味化合物都受到授粉的影响，尽管某些化合物对整体气味减少的影响更大。对样本进行分类，可以对授粉后个体植物的变化进行定量测试。授粉后引起的花香产生减少对植物和传粉媒介都具有适应性价值。
The effect of pollination on floral scent composition and production in the moth-pollinated orchid Platanthera bifolia was studied. A significant decrease in scent production was detected both two and five days after pollination. The proportion of wilted flowers was higher in pollinated compared to control plants after seven days. A principal component analysis (PCA) showed how pollination reduced scent production. All scent compounds were affected by pollination, even though some compounds had larger impact on the overall scent reduction. A classification of samples offered a quantitative test of the changes found in individual plants after pollination. The induced decrease in floral scent production following pollination is suggested to be of adaptive value for both plants and pollinators.
