These findings contribute to understanding water purification mechanisms in depth gradients, and support the effective rebuilding and management of submerged macrophyte communities in natural shallow lakes.īai X, Chen K, Zhao H, Chen X (2015) Impact of water depth and sediment type on root morphology of the submerged plant Vallisneria natans. Considering the growth status and nutrient removal effects, the results indicate that the optimal planting depth for H. Microbiological diversity analysis of biofilms indicates that community structure changes in response to water depth. The adjusted activities of glutamine synthetase (GS) and alkaline phosphatase (APA) were an adaptive nutrient utilization strategy to different water depths. Fluctuations in enzyme activities imply an antioxidant response to lipid peroxidation damage under different oxidative stress. The maximum shoot/root growth and chlorophyll (a + b) suggest photosynthesis inhibition is minimal at 1.2 m. At 0.9 m, the removal rates of TP and protein-like substances reached 78% and 18.67%, respectively, 1.76 times and 1.28 times the rates at 0.3 m. In the present study, changes in the aquatic microcosm were explored at the depth gradients of 0.3 m, 0.6 m, 0.9 m, 1.2 m, and 1.5 m, and the depth was recognized as a critical factor for improving water quality, especially for the removal of total phosphorus (TP) and recalcitrant protein-like molecules. The mechanism of morphological and physiological regulation of submerged aquatic plants ( Hydrilla verticillata) is influenced by spatial and environmental changes related to water depth gradients.
