Ex. Benth and Ocimum gratissimum Lindi are species from lamiaceae family of great medicinal importance, notwithstanding, they have been goals of few studies related to the cultivation techniques. Therefore, the study?s goal was to evaluate the behavior and tolerance of plants of H. fruticosa and O. gratissimum cultivated in vases submitted to different levels of evapotranspired water reposition during thirteen days (H. fruticosa) and nine days (O. gratissimum). The experiment was made in greenhouse under randomized complete block design with four treatments (100, 75, 50 and 0% of evapotranspired water reposition). It was verified that there were not any significant difference of total dry mass and leaf area among the treatments in the species H. fruticosa and O. gratissimum. Both of them presented the lowest values of relative water content, water potential, chlorophylls and carotenoids in the water reposition 0% treatment. In O. gratissimum, there was the decrease in net assimilation of carbon, stomatal conductance and transpiration with the water deficit increase, but the CO2 inside concentration was higher in the water reposition 0% treatment. The two species presented amino acid accumulation, proline, soluble proteins and soluble carbohydrate according to the water deficit increase. The essential oil content increased with the water availability increment in O. gratissimum, but it did not present the significant difference among the treatments in H. fruticosa. O. gratissimum revealed itself more sensitive and H. fruticosa more tolerant to the water deficiency. / Hyptis fruticosa Salzm. ex. Benth e Ocimum gratissimum Lindl. s?o esp?cies da fam?lia lamiaceae de grande import?ncia medicinal, no entanto, t?m sido objetos de poucos estudos relacionados ?s t?cnicas de cultivo. Assim, o objetivo deste trabalho foi avaliar o comportamento e toler?ncia de plantas de H. fruticosa e O. gratissimum cultivadas em vasos submetidas a diferentes n?veis de reposi??o de ?gua evapotranspirada durante o per?odo de treze dias (H. fruticosa) e nove dias (O. gratissimum). O experimento foi realizado em telado sob delineamento em blocos casualizados com quatro tratamentos (100, 75, 50 e 0% de reposi??o de ?gua evapotranspirada). Verificou-se que n?o houve diferen?as significativas da massa seca total e ?rea foliar entre os tratamentos nas esp?cies H. fruticosa e O. gratissimum. As duas esp?cies apresentaram os menores valores de teor relativo de ?gua, potencial h?drico, clorofilas e caroten?ides no tratamento 0% de reposi??o de ?gua. Em O. gratissimum, houve redu??o da assimila??o l?quida de carbono, condut?ncia estom?tica e transpira??o com o aumento do d?ficit h?drico, por?m a concentra??o interna de CO2 foi superior no tratamento 0% de reposi??o de ?gua. As duas esp?cies apresentaram ac?mulo de amino?cidos livres, prolina, prote?nas sol?veis e carboidratos sol?veis de acordo com o aumento do d?ficit h?drico. O teor de ?leo essencial aumentou com o incremento da disponibilidade h?drica em O. gratissimum, mas n?o apresentou diferen?a significativa entre os tratamentos em H. fruticosa. A esp?cie O. gratissimum mostrou-se mais sens?vel e H. fruticosa mais tolerante ? defici?ncia h?drica.
