With 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. |

It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of incident light interception during regrowth and they were evaluated combined to two defoliation severities (post-grazing conditions, 25 and 50 cm of height), being allocated to experimental units according to a complete randomized design, with three replicates and 3 × 2 factorial arrangement. The experiment was conducted from July 2003 to May 2004. For evaluation of morphogenetic and structural characteristics, ten tillers per experimental unit were selected. Morphogenetic and structural characteristics were strongly influenced by seasons of the year inasmuch as leaf elongation rate increased 3.5 fold from winter to summer. In addition to year season effect, there was also an effect of defoliation frequencies on tiller population density, which was greater in the defoliation period corresponding to 90% of light interception, especially if evaluated in relation to the interval corresponding to 100% of light interception. Defoliation frequency is determinant in expression of phenotypic plasticit, acting on the control of stem elongation. |
