Luxury Uptake and Removal of Phosphorus from Water Column by Representative Aquatic Plants and Its Implication for Wetland Management

Table 5

Relationship between total tissue P of Pistia stratiotes (TP), plant biomass (B), and residual dissolved inorganic P (RP) with incubation days (D) and DIP supply in the experimental basin. The squared multiple of correlation coefficient (𝑅²) and F statistics are also shown with multiple regression analysis.

Parameters	Regression equation	R^2	𝐹
P Tissue storage	TP = 0.0742 + 0.166D + 0.841P	0.998^b	859.9^b
Biomass	B = 83.92 + 1.823D − 0.952P	0.94^a	25.45^a
Residual P in Basin	RP = −0.282 + 0.929D + 0.021P	0.90^b	13.636^a

R² and 𝐹 values are significant: ^a𝑃<0.05, ^b𝑃<0.001, with d.f. 2, 3 for biomass, phosphorus tissue storage and residual phosphorus in basin.
