This study was designed to evaluate the effectiveness of salvinia [Salvinia minima) in accumulating nitrogen and phosphorus under different imitating eutrophic environments. Nitrogen concentrations of 1.0 (control), 10.0, and 100 mg/1 and phosphorus concentrations of 0.1 (control), 1.0, and 10.0 mg/1 were used in this study. Plants were grown under laboratory conditions at 25 ± 2 C with a light intensity of 120 umol/m 2 /s, and a 14 hr photoperiod. Salvinia's growth, expressed as frond production and plant fresh weight doubling time, was significantly increased with increasing nitrogen concentration from 1.0 mg/1 to 100.0 mg/1 in the growth media. The increase in growth rate was independent from the variation in phosphorus concentrations. However, the highest growth rate was obtained for days 1 through 7 when the levels of both nitrogen and phosphorus were elevated 100 fold (100 mg/1 N and 10.0 mg/1 P) from that of control
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
