WebThe coverages of floating-leaved macrophytes, submerged macrophytes and free-floating macrophytes inside the enclosure were up to 9.7%, 8.1% and 2.9%, respectively, one month after plantation. One year later, the coverage area of aquatic macrophytes (including emergent species) expanded and increased to about 45.7%.
WebOxygen may be released into water by some floating plants, such as water hyacinth from rootlets of which oxygen actively diffuses into water (see also Section 7.3.1). Submersed macrophytes oxygenate the water more effectively than floating-leaved macrophytes, as solid cover of the latter prevents effective reoxygenation from the air.
