dc.descriptionWith the increase in pollution of water bodies, there is a need to look for decontamination alternatives. Thus, there is a need for more studies aimed at removing these pollutants, with phytoremediation emerging as an alternative, using accumulator plants such as water lettuce (Pistia stratiotes), which is a macrophyte found in fresh surface waters with a high amount of organic matter. This study sought to assess how some growth parameters and the chlorophyll concentration of water lettuce might be affected when grown in different doses of salt. To this end, an experiment was carried out in which the plants were grown for 14 days in pots containing different doses of NaCl: T1: Control (0 g/L); T2: water + 2 g/L of a nutrient solution composed of Nitrogen, Phosphorus and Potassium (15-30-15); T3: 1% of the dose of sea salt diluted in water (0.35 g/L); T4: 5% (1.75 g/L) and T5: 10% (3.5 g/L), each with 5 replicates. Leaf number, plant neck diameter and chlorophyll concentration were analyzed. The number of leaves increased in all treatments, while the diameter decreased in the presence of the nutrient solution, and in the doses of 1.75 and 3.5 g/L. The chlorophyll concentration was higher in the nutrient solution and at the 3.5 g/L dose. This indicates that small doses of salt do not affect plant growth.
