The pomegranate (Punica granatum L.) fruit tree is shrubby, often used as an ornamental plant and operated as its medicinal characteristics. Its fruits have internal cavities that host numerous seeds and without the presence of endosperm. These seeds are germinating some difficulty, and it was possible to achieve satisfactory percentages of germination using laminating process that is required for breaking of physiological dormancy, as alters hormone balance, particularly gibberellin levels. The study aimed to evaluate the application of GA3 concentrations on germination of seeds of Punica granatum in controlled temperature of 25ºC and a photoperiod of 12 hours of light on paper germitest environment. We adopted the completely randomized design, with five treatments [GA3 concentrations (0, 100, 200, 300 and 400 mg L-1)], four replicates of 25 seeds each. It was determined during the acquisition curve imbibition of water from the same. The variables evaluated were germination percentage, mean germination time, germination velocity index, index of synchronization and frequency of germination, total length (shoot + root), fresh weight and dry weight of seedlings. The only variable that showed the effect of concentrations of GA3 was the emergence rate index. The soaking time required to achieve maximum water content in the seeds of pomegranate tree (P. granatum) in deionized water was four hours, this soaking liquid effective method for the germination process, without the need to Gibberellin.
