常考释义
n. [植] 柱头
Small grains may be blown farther but they are also more prone to be whisked past the waiting stigma because smaller particles tend to stay trapped in the fast-moving air that flows around the stigma.
小花粉可能被吹得更远，但它们也更容易拂过花的柱头，因为较小的颗粒会被困在在柱头周围快速流动的空气中。

来源于：阅读OFFICIAL34 P3Most deciduous wind-pollinated trees (which shed their leaves every fall) produce their pollen in the spring while the branches are bare of leaves to reduce the surrounding surfaces that “compete" with the stigmas (the part of the flower that receives the pollen) for pollen.
大多数风媒传粉的落叶植物（每年秋天落叶的植物）在春天产出花粉，这时候树枝光秃秃的，花粉就有更大几率落到柱头（接收花粉的部分）上，落到树的表面上的部分就不会太多。
来源于：阅读OFFICIAL45 P2But stigmas create turbulence, which slows the air speed around them and may help pollen stick to them.
但与此同时柱头处也会有动荡，从而降低风速，有助于花粉附着在柱头上。
