Aiming to evaluate the use of 'Smooth Cayenne' pineapple plant crowns on yielding planting material of the suckers type, pineapple crowns, weighting from 200 to 300 g, were planted in pots containing 5 dm³ of substrate, in a greenhouse. Fifteen and thirty days after being planted, they were pulverized with 10 mL of GA3 (0, 100, 200 and 400 mg L-1) and BAP (0, 100, 200 and 400 mg L-1) combining the concentrations totalizing 16 treatments with four replicates. The experimental outline was in randomized blocks in a 4 x 4 factorial scheme. Effects of GA3 and BAP on shoot emission were evaluated every two-month intervals. The highest rates of shoot emission were 1,81 shoots every 60 days and a total average of 12.6 shoots at 420 days after planting, under 230 mg L-1 of BAP. There were no GA3 or BAP effects on the number, weight and length of the largest offshoots harvested at 124, 214, 314 and 360 days. In a 365-day-period after planting, an average of 5.2 offshoots were harvested, with 145 g of average weight and 35.9 cm in length.
