%X O objetivo deste trabalho foi estudar a influ¨ºncia da sacarose (0; 15 e 30 g L-1), tipo de veda  o (filme de PVC e tamp o de algod o) dos tubos de ensaio, e a concentra  o dos sais do meio MS (50; 75 e 100%) sobre os aspectos morfofisiol¨®gicos das plantas de caro¨¢ durante a fase de pr¨¦-aclimatiza  o in vitro visando otimizar a taxa de sobreviv¨ºncia e reduzir o tempo de aclimatiza  o das mudas. A an¨¢lise das caracter¨ªsticas de comprimento, produ  o de mat¨¦ria seca, taxa de sobreviv¨ºncia e enraizamento mostraram que as plantas de Neoglaziovia variegata nas fases de pr¨¦-aclimatiza  o in vitro e aclimatiza  o foram dependentes das concentra  es de sacarose e nutrientes inorganicos, al¨¦m da aera  o. Melhores resultados foram obtidos quando as mudas de caro¨¢ foram inoculadas em meio MS com a concentra  o original dos sais do MS, suplementado com 15 ou 30 g L-1 de sacarose e vedadas com tamp o de algod o. This work aimed to evaluate the influence of sucrose (0; 15 and 30g L-1), the type of seal used in the test tubes (PVC film or cotton plug), and salt concentration in the MS medium (50%; 75% and 100%) on the morphological and physiological traits of caro¨¢ plants during in vitro pre-acclimatization phase aiming to optimize the survival rate and shorten the acclimatization period of the seedlings. The analysis of characteristics such as length, dry matter production, survival rate and rooting, showed that Neoglaziovia variegata plants at pre-acclimatization and acclimatization stages were dependent on sucrose concentrations, inorganic nutrients from MS medium and aeration. The best results in the acclimatization stage were obtained when the caro¨¢ seedlings were inoculated in MS medium with the full salt concentration, supplemented with 15 or 30g L-1 sucrose, and sealed with cotton plugs during the pre-acclimatization stage.
