The forage cactus is cultivated of extensive form as a producing species of fruits and fodder plant in many countries. The extensive culture if bases on the vegetative propagation, that is preferred, had its easiness. The propagation for seeds can come to be a useful tool for ends of genetic improvement, then, in this work forage cactus (Opuntia ficus-indica L.) seeds were submitted to different fermentation periods (0; 24; 48; 72 and 96 hours) and were dried or not, before sowing. It was evaluated the physiological quality of the seeds through the determination of the moisture content, emergence percentage and speed of seedling emergency. It was used an entirely randomized experimental design 5x2 (period of fermentation and drying). The practical one of the fermentation is efficient in the elimination of the sarcotesta in palm seeds, occurring bigger vigor in the seeds without drying and submitted the 55 hours of fermentation, as well as, the drying of the seeds, after the first periods of fermentation promotes reduction of the physiological quality, with reflected right-handers in the vigor.
