The maize plant bears two kinds of flowers, -male and female.

玉米开的花有两种——雄花和雌花。

Instead, they rely on outside forces to transport their tiny pollen grains from male flower parts to female ones.

取而代之的，它们依靠外部力量将微小的花粉粒从雄花转移到雌花。

B. Male and female flowers grow on the same plant.

B. 雄花和雌花在同一株植物上。

The female flowers are about three-eighths of an inch long, pale green, and grow in countless thousands on the ends of sprays.

雌花约八分之三英寸，呈淡绿色，在花束的末端出无数。

The male flowers are on the tassel; the fine silk threads which surround the ear, and peep out from the end of the husks, are the female flowers.

而那种围绕着包谷生并在包皮的末端隐约露出的丝一样的细，雌花。

Each grain on the cob is the starting point for a thread of silk; and, unless the thread receives some particle of the dust which falls from the tassel flowers, the kernel with which it is connected will not grow.

玉米穗轴上的每一个颗粒都一束丝状雌花的起点，除非花束获得来自于穗状雄花的微粒，否则它所连接的内核无法成。

The weather had been cold and boisterous and therefore not favourable to bees, nevertheless every female flower which I examined had been effectually fertilised by the bees, which had flown from tree to tree in search of nectar.

天气寒冷而喧闹， 因此对蜜蜂不利， 但我检查过的每一朵雌花都被蜜蜂有效地授粉， 蜜蜂从一棵树飞到另一棵树上寻找花蜜。
