A capacidade regenerativa de gemas axilares de abacaxizeiro cv. Pérola (Ananas comosus (L.) Merr.) foi avaliada em meio de cultivo líquido e gelificado, na presença e ausência de luz, com o objetivo de produzir material para subsequentes fases da micropropagação. Os explantes foram estabelecidos, por 60 dias, em meio MS acrescido de 0,63 &#956;M de ANA e 2,5 &#956;M de BAP. O delineamento experimental foi inteiramente casualizado, constituído com quatro tratamentos (meio líquido com e sem ponte de papel de filtro e meio gelificado com ágar a 6,0 g L-1 e com Phytagel® a 3,0 g L-1), com quatro repetições e cinco explantes por repetição. Diferentes volumes de meio líquido (2,5 mL; 5,0 mL e 10,0 mL) também foram avaliados, usando-se quatro repetições por volume de meio de cultura. Maior número de brotos foi obtido na presença de luz, em meio líquido sem ponte de papel de filtro, onde 80% dos explantes se diferenciaram em brotos. Na ausência de luz, 68,8% a 87,5% dos explantes não regeneraram brotos. Explantes cultivados em volumes de 5,0 mL ou 2,5 mL de meio MS líquido, acrescido de 0,63 &#956;M de ANA e 2,5 &#956;M de BAP, na presença de luz, constitui um protocolo adequado para cultivo inicial de gemas axilares e regeneração de brotos de abacaxizeiro. The regenerative capacity of buds from lateral sprouts of the pineapple cv. Pérola (Ananas comosus (L.) Merr.) was evaluated in liquid and semi-solid medium, under light and dark conditions, with the objective of producing materials for subsequent phase of micropropagation. The explants were established for 60 days in basal MS medium, supplemented with 0.63 &#956;M NAA and 2.5 &#956;M BAP. The statistical design was completely randomized with four treatments (liquid medium with and without filter paper bridge, and semi-solid medium gellified with agar and phytagel®), four repetitions and five explants per experimental unit. Different volumes of liquid medium (2.5 mL, 5.0 mL, and 10.0 mL) were also evaluated in four replications per treatment. More buds were obtained in liquid medium without filter paper bridge, where 80.0% of explants differentiated new shoots. In treatments cultivated in the dark, 68.8% to 87.5% of the explants did not regenerate new shoots. Explants cultivated in volumes of 2.5 mL and 5.0 mL of medium, in the presence of light, were more efficient in the induction and formation of shoots. The cultivation of axillary buds of lateral pineapple sprouts in 2.5 mL or 5.0 mL of MS liquid medium, supplemented with 0.63 &#956;M NAA and 2.5 &#956;M BAP, in the presence of light, represents an adequate protocol for establishing new pineapple shoots for use in subsequent phases of micropropagation
