The environmental and economic potential of long pepper (Piper hispidinervum) requires the development of methodology to evaluate seed potential physiological. The work aimed to evaluate the physiological potential of long pepper seeds (Piper hispidinervum C. DC.) through different tests and accelerated aging. Seeds were harvested in four different commercial planting and evaluated to water content (%), germination (G%), germination speed index (GSI), seedling emergence (SE%), emergence rate index (ERI) and accelerated aging (AA 41 and 45 °C during 24, 48, 72 and 96 hours). The experimental design was completely randomized with a simple scheme for G, GSI, SE and ERI, and 4 x 4 factorial (lots and times) at each temperature for AA. Physiological potential of long pepper seeds can be evaluated by germination test, germination speed index, seedling emergence, seedlings emergence speed index and accelerated aging at 41 °C during 24 hours.
