Pineapple cultivars, ?Smooth Cayenne?, ?Pérola?, ?Jupí? and ?Favo de Mel?, planted in May 2001 were induced to bloom with ethefon at eight, nine and ten months after the planting date using slips weighting approximately 200 g. The analyzed characteristics were evaluated in relation to fruit weight without crown (FWC), relation °Brix/acidity (RBA) and vitamin C content (VC), in a RCBD with 4 replications factorially arranged at 4 x 3 (genotypes x environments). F-test and Tukey at 5% were applied. In FWC it was not identified a significant interaction between genotypes and induction treatments, showing values of 1055,23 g (a), 949,20 g (a), 937,87 g (a) and 638,07 g (b), respectively for ?Smooth Cayenne?, ?Jupí?, ?Pérola? and ?Favo de Mel?. The highest average occurred for induction on the ninth and tenth months. RBA and VC presented significant genotypes x environments interactions. In ?Smooth cayenne?, VC was not affected by the induction treatment, showing average of 12,68 mg 100 g-1. In RBA the averages were verified: 6,72 (c), 15,10 (a), 11,51 (b), respectively, at induction of eighth, ninth and tenth months. For the ?Pérola?, VC averages were: 28,03 mg 100 g -1 (b), 38,08 mg 100 g-1 (a) and 27,63 mg 100 g-1 (b), at induction of eighth, nineth and tenth month, and RBA averages were: 15,50 (b), 18,22 (a), 14,10 (b), respectively. The induction treatment did not affect the RBA for ?Jupí? and ?Favo de Mel?, with respective averages, 13,84 and 14,12. It was verified in ?Jupí? the highest VC (40,00 mg 100 g-1) in fruits of induced plants at ten months, while ?Favo de Mel? presented its highest content (24,99 mg 100 g-1) at eight months.
