我们提出的证据表明，授粉引发附生兰花蜜重吸收。花蜜中的糖分在授粉后72小时内显著下降50%以上。与含有花蜜的人工授粉花相比，先前去除花蜜的人工授粉花结出的果实明显更小，可存活种子的比例更低，这表明通过花蜜再吸收回收的资源被分配到果实生产上。
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.
