Conteúdo: 	Evaluation of best temperature regime for pineapple seed ger-mination was the aim of this study, in support to pineapple breeding program. Seeds obtained from crosses between Perolera (PE) and Primavera cultivars and from two backcrosses: BRS Imperial x Smooth Cayenne (SC) and (PE x SC-60) hybrid x Smooth Cayenne, were used. Seeds were kept under constant temperature of 25°C and alternating 25-20, 30-20 and 35-25°C within a 14 hour photoperiod. Experimental design was completely randomized in a 4x3 factorial arrangement with four temperature regimes, three progenies with four replicates of 75 seeds. Seeds were assayed twice a week, in three or four day intervals to measure percentage and germination rate, ranging from twenty five to 60 days after sowing. Results show differences in percentage of seed germination and germination rate among progenies and optimum temperature for seed germination in all progenies is 25°C.
