Traditionally , pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen , so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used 传统上来讲，风媒传粉一直被看作是一个繁殖过程，它以随机事件为标志，在此过程中，风的奇怪行为被大量花粉的产生所补偿，因此，最终新种子的产生被保证，是依靠产生的花粉数量要大大超过实际的使用量。
