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. 达尔文推理说一定有一种蛾子喙很长，能够够到蜜腺。 物种起源 When the colour is absent from only one of the two upper petals, the nectary is not quite aborted but is much shortened. 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。 |
