摘要被子植物花粉粒与访花昆虫的粘附机理因花粉丝和粘素丝的不同而不同。花粉囊在被子植物的所有科中都有发现，但粘丝仅在少数科中出现。此外，这两种花粉胶结原理在其来源、结构、雕刻、化学和物理性质上并不一致。甚至花粉胶结的机械方面也不同。因此，在传粉生态学中，花粉和粘丝是类似的媒介。
Abstract The principle of attachment of pollen grains to flower-visiting insects is quite different in entomophilous angiosperms depending whether pollenkitt or viscin threads are the pollen adhesives. Pollenkitt is to be found in all angiosperm families investigated up to now, but viscin threads occur only in a small number. Moreover, the two pollen cementing principles do not correspond in their respective origin, structure, sculpture, and chemical and physical characters. Even the mechanical aspect of pollen cementing differs. Thus pollenkitt and viscin threads are analogous vehicles in pollination ecology.
