Abstract

We present evidence that pollination triggers nectar reabsorption in flowers of the epiphytic orchid Mystacidium venosum. The amount of sugar in nectar of M. venosum decreased significantly by more than 50 percent within 72 hours of pollination. Hand-pollinated flowers from which nectar was previously removed set significantly smaller fruits with a lower percentage of viable seeds than hand-pollinated flowers containing nectar, suggesting that resources reclaimed by nectar resorption are allocated to fruit production.
