The Brazilian market of tropical flowers is in a rapid growth stage. The climate of the Brazilian northeastern region, however, tends to hamper plant acclimatization. Considering this, our study aims at determining the most appropriate container (concerning to capacity) to acclimatize micropropagated Torch Lily (cultivar Porcelana) in a greenhouse. The experimental design was randomized blocks with four treatments (container capacities) and five replications. The tested container capacities were: V1 = 50cm³ (small glass - CP); V2 = 150cm³ (small plastic tube - TP); V3 = 300 cm³ (large plastic tube - TG); V4 = 450cm³ (small vase - VP). The characteristics evaluated were: the number of leaves (NF), seedling height (AM), stem diameter (DP), fresh shoot weight (MFPA), fresh root weight (MFSR), dry shoot weight (MSPA) and dry root weight (MSSR). Data were examined by analysis of variance and the Tukey test. The results point to the 450cm³ container as the best suited for Torch Lily acclimatization, since it provided the best seedling growth.
