Gymnosperms don't make nectar, but they do make nutritious pollination drops that are used for trapping airborne pollen.

裸子植物不产生花蜜，但它们确实产生有营养授粉滴，获空气中花粉。

Experiments show that both animals can actually remember the locations of the most rewarding, nectar-rich flowers in a field filled with blooms.

实验表明，这两种动物实际上都能记住开满鲜花田野中最有价值、花蜜最丰富花朵位置。

Color in short hand that says to a bee: hey, I get some good quality nectar here, want to stop by for a visit.

简写颜色对蜜蜂说：嘿，我这里有一些优质花蜜， 想过来看看。

This is POG, I drank this growing up, so there's definitely a lot of nostalgia with this, but it's passion fruit, orange, and guava nectar in a can.

这是 POG， 我从这个，所以肯定有很多怀旧之情，但它是罐装百香果、橙子和番石榴花蜜。

Several plants habitually produce two kinds of flowers; one kind open and coloured so as to attract insects; the other closed, not coloured, destitute of nectar, and never visited by insects.

一种是开放， 有颜色，以吸引昆虫； 另一个是封闭， 没有颜色，没有花蜜，也从未被昆虫光顾过。

The plants which produced flowers with the largest glands or nectaries, excreting most nectar, would oftenest be visited by insects, and would oftenest be crossed; and so in the long-run would gain the upper hand and form a local variety.

开花植物有最大腺体或蜜腺， 分泌最多花蜜， 最常被昆虫光顾， 也最常杂交；因此，从长远来看， 它们将占据上风并形成本地品种。
