摘要在乌得勒支市（荷兰）附近的一个沙坑费希滕湖中，沉水植物植被以两种植物为主，即金鱼藻和加拿大伊乐藻。在一年中，这两个物种都能够发育出两种不同的形式：夏季的正常营养形式，冬季的休眠形式。伊乐藻通过根固定在基质上，金鱼藻通过改良的叶子固定在基质上，格鲁克（GLÜCK）将其称为假根（1906，1911）。两个物种形成不同的区域。植物大量出现的深度，伊乐藻属为 0 至 3 m，金鱼藻属为 3 至 5 m。
SummaryIn Lake Vechten, a sandpit near the city of Utrecht (The Netherlands), the submerged macrophyte vegetation is dominated by two species, namelyCeratophyllum demersum andElodea canadensis. In the course of the year both species are able to develop two distinct forms: the normal vegetative form in summer, the dormant form in winter.Elodea is anchored to the substrate by roots,Ceratophyllum by modified leaves, called rhizoids by GLÜCK (1906, 1911). Both species form distinct zones. The depth at which the plants occur abundantly is 0 to 3 m in the case ofElodea and from 3 to 5 forCeratophyllum.
