杨属是杨柳科中适应风媒的分支;
Populus is branch of wind pollination and Salix is an other branch of insect pollination.
然而,一些关于苏铁风媒传粉的传闻也不容忽视。
Nevertheless, anecdotal reports of wind pollination in cycads cannot be ignored.
肺结核是一种风媒传播的疾病并且依然有7%的致病率。
TB is an airborne infection which still proves fatal in about 7% of cases.

有关风媒传粉是在昆虫稀缺或靠不住的时候才启用的论述,见cox,P .A . 1991。
For the argument that wind pollination takes off when insects are scarce or in some other way unreliable, see Cox, P. A. 1991.
有关风媒传粉的植物花粉粒数量大于虫媒传粉植物的数据,见Cruden,r .W . 2000。
For the large Numbers of pollen grains produced by wind-pollinated plants as compared to insect-pollinated plants, see Cruden, R. W. 2000.
有关达尔文对风媒传粉效率的持疑,见darwin,C . 1876。
For Darwin's skepticism about the efficiency of wind pollination, see chapter 10 of Darwin, C. 1876.
肺结核是一种风媒传播的疾病并且依然有7%的致病率。几乎一半的病人有多种药物的耐药现象发生并导致死亡。
TB is an airborne infection which still proves fatal in about 7% of cases. Almost half of patients with the multi-drug resistant form of the disease die.
花柱可在进化中相应的被延长以适应风媒、虫媒、或动物传粉等不同方式,可以使柱头有更大的机会与传粉者相接触。
The style may be elongated in plants relying on wind, insect, or animal pollination so that the stigma has a greater chance of coming into contact with the pollinating agent.
蜜蜂看不见红色,但它们可以看见其它鲜艳的颜色。红色花卉通常依靠鸟类、蝴蝶、蝙蝠和风媒进行授粉,而不是靠蜜蜂。
Bees can't see the color red, but they can see all other bright colors. Red flowers are usually pollinated by birds, butterflies, bats, and wind, rather than bees.
蜜蜂看不见红色,但它们可以看见其它鲜艳的色彩。红色花草凡是依附鸟类、蝴蝶、蝙蝠和风媒进行授粉,而不是靠蜜蜂。
Bees can't see the color red, but they can see all other bright colors. Red flowers are usually pollinated by birds, butterflies, bats, and wind, rather than bees.
然而,风媒传粉植物的一些特点会减少花粉浪费。
However, a number of features that are characteristic of wind-pollinated plants reduce pollen waste.
是一种避免自花授粉的机制,在风媒花和非专性虫媒花中最为普遍,比方说玄参。
It is a mechanism that helps prevent self-pollination and is most common among wind-pollinated and unspecialized insect-pollinated flowers, as in figwort.
