It is an organ of perennation or vegetative propagation, and is characteristic of various water plants (e.g.Sagittaria).

这是多年生营养繁殖器官，还是多种水生植特征之一(例如：Sagittaria)。

Quillworts are heterosporous, mainly aquatic perennials, with a dense rosette of tubular quill-like leaves arising from a short, stout rootstock.

水韭目植有异型孢子，是多年水生植。其管状条形叶密集簇生于粗短根茎之上。

The result indicates that great differences,which have significant influence on the aqua-plants,exist in the evapotranspire,the bio-mass,the root density and the root length.

研究结果表，不同水生植蒸散量、生量、根密度和根长存在较大差异，这些差异对水生植性能、碎石床人工湿地水力负荷率、氮磷去除效果和有机污染降解有重要影响。

In any navigation channel, the following activities are prohibited: abandoning sunken vessels, laying fishing implements impedimental to navigation, and cultivating aquatic plants.

在航道内不得弃置沉船，不得设置碍航渔，不得种植水生植。
