No. of bitstreams: 0 Previous issue date: 2007-11-01 The research aimed at the evaluation of the influence of different potassium doses on the growth and development of Mentha piperita L. The experiment was conducted with stalks rooted in a commercial substrate and transplanted to a complete nutritive solution varying the treatments as following: (a) 234 mg L-1 of K; (b) 117 mg L-1 of K; and (c) 58.5 mg L-1 of K. Plants were evaluated at 21, 42, 63, 84 and 105 days after transplanting (DAT). In this study there were determined the physiological indexes leaf area ratio (LAR), specific leaf area (SLA), net assimilatory rate (NAR) and relative growth rate (RGR) were determined. The results indicated that the decreasing of K concentration to 25% did not affect the LAR, SLA, NAR and RGR physiological indexes.
