The present work aimed at evaluating the rate of survival of micro propagated young plants of banana under different acclimatization conditions. Young banana plants 'Prata Anã', from micro propagation, with 2-3 cm of length were planted in little tubes filled with the commercial substratum Plantmax. The trays with the little tubes were placed in small greenhouse with transparent plastic covering to acclimatization in different conditions of luminosity. The treatments were composed by: T1- Acclimatization chamber with covering of amianthus roof, T2- Acclimatization chamber under mesh, with 50 % of shading and T3- Acclimatization chamber covered with paper type Kraft and under mesh, with 50 % of shading. The experimental design was entirely randomized, with three treatments and seventy repetitions. The plants remained for 15 days in the related treatments, when the first evaluation was carried through. The second evaluation occurred at 30 days after planting. The evaluated characteristics were length of the young plants; diameter of point of connecting of root and stem, number of completely expanded leaf and percentage of establishment. These characteristics were submitted to the variance analysis, being the effect of the treatments compared by the Tukey test, at 5% of probability. In the first evaluation, were observed 100 % of the plantlets survived at the three tested conditions of luminosity. At the thirtieth days after the plantation the plants acclimatized in chamber under mesh with 50% of shading, presented the greatest averages of length, diameter and number of leaves, with 4.6 cm; 0.64 cm e 5.5 leaves, respectively.
