For example，the spiral arrangement of scale-bract complexes on ovule-bearing pine cones，where the female reproductive organs of conifers are located，is important to the production of airflow patterns that spiral over the cone's surfaces，thereby passing airborne pollen from one scale to the next.

　　例如，帶有胚珠的松球的鱗苞綜合體的螺旋狀安排，亦即松柏目植物雌性殖器官的所在位置，對(duì)于氣流模式的形成與產(chǎn)生殊為重要，而這些氣流模式在松球的表現(xiàn)盤旋上升，從而把在空氣中飛行的花粉從一個(gè)鱗苞傳播至下一個(gè)鱗苞。

　　Because the potential hazards pollen grains are subject to as they are transported over long distances are enormous，wind pollinated plants have，in the view above，compensated for the ensuing loss of pollen through happenstance by virtue of producing an amount of pollen that is one to three orders of magnitude greater than the amount produced by species pollinated by insects.

　　由于花粉粒在其長(zhǎng)距離的運(yùn)輸過程中所要面臨的潛在危險(xiǎn)是巨大的，按上述觀點(diǎn)來看，由風(fēng)授粉的植物補(bǔ)償了通過偶發(fā)事件而伴隨造成的花粉損失。其途徑是，制造出大于昆蟲授粉的植物種類所產(chǎn)生的花粉量的一至三個(gè)數(shù)量級(jí)的花粉量。
