摘要

The micropropagation of plants is extremely useful in the multiplication of new cultivars in wide scale. The pineapple tree Vitória is a cultivar with the important characteristic of being resistant to the fusariosis. After cultivation in vitro and acclimatization is possible to produce seedlings of different sizes, meantime a standard size has been used for marketing. The use of seedlings of different stages of growth, after the acclimatization, can interfere in the final quality of the seedlings for the planting in the field. The object of this work was to evaluate the effect of the different sizes of pineapple tree 'Vitória' seedlings, after acclimatization, in the capacity of these after the period of acclimatizing. Were selected micropropagated seedlings of the pineapple tree 'Vitoria', acclimatized in Green house with different sizes and these were planted in stonemason open sky for the acclimatizing, for a period of 150 days. It was used randomized complete block design, factorial scheme 5x2, corresponding to five periods of acclimatizing of the seedlings (30, 60, 90, 120 and 150 days) and the two times of evaluation (beginning and at the 150 days of the acclimatizing). The treatments were valued regarding the number of leaves , leaf area, height of the plant, diameter of rosette, length of the most developed leaf, dry mass and fresh mass of the air part. For the conditions of this experiment, it was verified that seedlings with 60, 90 120 and 150 days after acclimatization present conditions for acclimatizing.
