| ABSTRACT It is known the fact that the mining causes huge damages on the environment having negative biologic effects extremely severe on some groups of organisms of the food chain. The pollutants causes major damages at the level of leaves' cuticles, the vegetation reacting through irreversible modifications at the tissue's level and at substances and energy metabolism, like a riposte to the apparition of the stress induced by the ROS, stress that creates real disturbances on physiological and biochemical processes. Considering the fact that, on the one hand, the activity of oxidoreductases is strongly influenced by the presence of the pollutants factors, with direct effect on the oxidative's stress production, and on the other hand that the plants react... |

| The influence of potassium on the development of Mentha piperita L. was evaluated in the plants grown in nutritive solution modified by variations in potassium, at 6.0, 3.0, and 1.5 mmol L-1, establishing differences between treatments and corresponding, respectively, to the concentration proposed in Hoagland and Arnon's no. 2 solution and reductions by 50% and 75%. Until 21 days after transplanting, the concentration used was diluted to 50% in the three treatments. Evaluations consisted of leaf area, development of the above-ground part, and dry matter of different plant organs. Plants grown with 1.5/3.0 mmol L-1 K showed greater development of the above-ground part. Other variables were not different among plants in the different treatments. |
