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

玉米开的有两种——雄。

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

取而代之的是，它们依靠外部力量将微小的粉粒从雄转移到。

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

B. 雄在植物上。

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

约八分之三英寸，呈淡绿色，在束的末端出无数。

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样的细线，就是。

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.

玉米穗轴上的每个颗粒都是束丝状的起点，除非束获得来自于穗状雄的微粒，否则它所连接的内核就无法成。

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， 但我检查过的每朵都被蜜蜂有效地授粉， 蜜蜂从棵树飞到另棵树上寻找蜜。
