Nectaries are plant glands that secrete nectar, a solution rich in carbohydrates but also containing other solutes at lower concentrations. Despite being small and cryptic, nectaries are extremely important ecologically for fostering beneficial interactions between plants and organisms in their environment, both in Canada and internationally. Floral nectaries typically reside in strategic locations leading to the visitor's contact of anthers (pollen-producing organs) and stigmas (pollen-receiving sites, where pollination occurs). Thus, mutualistic relationships occur when flower-visiting animals such as bees and other insects gather nectar as an important food source from floral nectaries, leading eventually to seed and fruit set. Major parts of our daily diets can be attributed directly to pollination by insects, and hence to nectaries. Some flower bases even possess spurs, tubular extensions that conceal nectar available only to animals with sufficient tongue length to attain it. And for an extremely beneficial species, the honey bee (

蜜腺是分泌花蜜的植物腺体，花蜜是一种富含碳水化合物的溶液，但也含有较低浓度的其他溶质。 尽管是小而神秘的，蜜腺是非常重要的生态促进植物和生物之间的有益的相互作用，在加拿大和国际上的环境。 花蜜腺通常位于战略位置，导致访问者接触花药（产生花粉的器官）和柱头（花粉接收地点，授粉发生）。 因此，当访花动物如蜜蜂和其他昆虫从花蜜中采集花蜜作为重要的食物来源时，互利关系就会发生，最终导致种子和果实。 我们日常饮食的主要部分可以直接归因于昆虫授粉，因此蜜腺。 有些花的基部甚至有刺，管状的延伸部分，隐藏着花蜜，只有舌头足够长的动物才能得到花蜜。
