原声例句
昆虫王国第二季 （原声版）

Darwin made the deduction that there had to be a moth there with the beak long enough to reach the end of nectary.

物种起源

当两个上部花瓣中只有一个没有颜色时， 蜜腺并没有完全流产， 而是大大缩短了。

PBS地球-动物趣闻

Like, organs called nectaries evolved, which delivered tasty nectar rewards to pollinators - these were a new take on the old pollination drops of gymnosperms.

比如， 进化出蜜腺器官，将美味的花蜜奖励给传粉者——这些是对裸子植物旧授粉滴的新诠释。

物种起源

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.

开花的植物有最大的腺体或蜜腺， 分泌最多的花蜜， 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。

花蜜 Nectar

（重定向自Nectary）

花蜜是开花植物的花内蜜腺等分泌的一种主要成分是小分子糖类、比如双糖的蔗糖、单糖的果糖、葡萄糖及半乳糖、甚或三糖棉子糖，四糖水苏糖等的混和物，其种类与比例会随物种甚或品种有相当变化。可吸引授粉昆虫来采蜜，从而达到帮助授粉的目的。蜜蜂采集花蜜可酿成蜂蜜。

花蜜的浓度会随环境而变化，比如椴树在空气湿度为51%时，花蜜含糖量为72%；湿度为100%时，含糖量只有22%。蜜蜂喜欢采食含糖高的花蜜。

然而部分花蜜与花粉对蜜蜂具有毒性，比如含有半乳糖的茶花，以及钾离子含量偏高的枣花；甚或对人具有毒性，比如雷公藤（Tripterygium wilfordii Hook.F.）、博落回 （Macleaya cordata (Willd.) R.Br）、狼毒（Stellera chamaejasme L.）。

Nectar 花蜜

（重定向自Nectary）
Nectar of camellia
An Australian painted lady feeding on a flower's nectar
Extrafloral nectaries on the petiole of a wild cherry (Prunus avium) leafExtrafloral nectaries on a red stinkwood (Prunus africana) leaf

Nectar is a sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide antiherbivore protection. Common nectar-consuming pollinators include bees, butterflies and moths, hummingbirds, and bats. Nectar plays an important role in the foraging economics and overall evolution of nectar-eating species; for example, nectar and its properties are responsible for the differential evolution of the African honey bee, A. m. scutellata and the western honey bee.
