Results of analyses of variance (F_(1,33)-ratios) for P uptake kinetic parameters of Cladium mariscus spp. jamaicense and Typha domingensis against species, P level (5 and 500 μg P l^-1) and oxygen level (8.0 and <0.5 mg O₂ l^-1) in the hydroponic culture solution. Significant effects are in bold and indicated by *(P < 0.05), **(P < 0.01) and ***(P < 0.001).
