The objective of this study is to verify the behavior and growth parameters of four cultivars of basil. The seeds were bought locally and grown in pots with the following measures: 11.8 cm diameter x 8.6 cm diameter x 9.0 cm high, in a greenhouse with regular cultivation. The treatments were a combination of four cultivars of basil and five stages of evaluation, with a 4x5 factorial arrangement, in a completely randomized design with three replications. Each experimental unit consisted of ten plants. The cultivars used were: Anão (Dwarf); Folha Larga (Broad-leaf); Grecco and Roxo (Purple). The stage of evaluation was determined by equidistant intervals of 14 days after sowing - DAS (46, 60, 74, 88 and 102 DAS). The following characteristics were evaluated: stem length (CC), biomass (BG), dry mass of leaves (MSF), dry mass of stem (MSC) and dry mass of root (MSR); SPAD; leaf area (AF); leaf area index (IAF); specific leaf area (AFE); leaf mass fraction (FMF), stem mass fraction (FMC) and root mass fraction (FMR); net assimilation rate (TAL); growth rate of the cultivation (TCC) and relative rate of cultivation (TCR). The data was subjected to analysis of variance and regression. For the qualitative factor, the averages were compared by the Tukey test at 10% probability. CC, BG, MSF, MSC, MSR, AF, IAF and AFE varied over the cycle with a linear behavior for the four cultivars. For stages 60, 74 and 88 DAS, the Roxo (Purple) cultivar was superior to the others for the CC variable. In average characteristic production of BG, MSF and MSR, the Folha Larga (Broad-leaf) cultivar was superior to the others. For variables SPAD, AF, IAF and AFE the Roxo (Purple) cultivar has the best results, on average. The four varieties of basil have aptitude for potted production. Can be used as ornamentals for the Grecco and Anão cultivars, because they have a shorter length of stem. The Folha Larga and Roxo cultivars showed better potted growth performance than the Anão and Grecco cultivars. The best stages for the exploitation of cultivars in pots are at 60, 74 and 88 days after sowing.
