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.
