Abstract

The experiment was carried out in a greenhouse, in the Centro de Ciências Agrárias da Universidade Federal do Espírito Santo, located in Alegre city, Brazil. The work had as objective to evaluate the foliar and radicular growth of micropropagated plantlets of the pineapple cv. Gold [Ananas comosus (L.) Merrill] in phase of the acclimatation. The experiment was set up in arrangement of split plot, being evaluated the growth of that genotype in 5 different ages of retreat of the greenhouse of pre-acclimatation: 0; 1; 2; 3 and 4 months and the witness that stayed there for 5 months, consisting in plots and evaluations to the: 0; 30; 60; 90; 120 and 150 days after transplanted, forming the subplots.
