摘要：Vallisneria natans, a submersed freshwater macrophyte, was used in a small-scale restoration experiment in shallow, eutrophic, Chinese lakes. Seeds distributed to the substrate germinated well, and seedlings emerged en mass, which supports the idea that using seeds may be an effective way to propagate this macrophyte and may be a first step in restoring shallow eutrophic lakes such as those in the middle and lower reaches of the Yangtze River. Although there was no significant effect on seedling germination and emergence, water depth played a key role on the early growth of V. natans, as measured by plant biomass and maximum leaf length.
