Resumo: 	The success in micropropagation of Dendrobium phalaenopsis Deang Suree is high, but when transplanted into the greenhouse, their survival is minimal. To increase survival in production in the present study it was evaluated the effect of intermediate acclimatization for 30 days in a grow room utilizing the following luminosity conditions: 1- white fluorescent light (B) (18.9µmol m-2 s-1); 2- white fluorescent light + red fluorescent light (GRO-LUX(r)) (BV) (14.85µmol m-2 s-1); 3- red fluorescent light (GRO-LUX(r)) (V) (9.45µmol m-2 s-1) and the control plants were accommodated directly in a greenhouse (162.0µmol m-2 s-1). After this the leaves were characterized anatomically and the plants transferred to the control greenhouse. It was evaluated survival percentage and final number of roots, and calculated the relations between the final and initial values of fresh weight, number of leaves, length and diameter of the largest pseudo bulb, number of pseudo bulbs and longest root length. Only plants submitted to red light, were statistically better than the control in relation to the survival percentage and in relation to fresh weight, while the control showed a higher number of roots that plants acclimatized in this luminosity conditions. Intermediate acclimatization, using red light or red + white light, is recommended for D. phalaenopsis Deang Suree.
