The effect of gibberellic acid ultradiluted (dynamizations 1CH to 12CH) on germination of lettuce and sunn hemp seeds was evaluated. The sunn hemp seeds were stored in cold chamber per one year and kept for six months under refrigeration before receiving homeopathic preparations in the water from imbibition during two hours. After that the seeds were placed on a germitest sheet of paper inside the gerbox and humidified with 0.7 mL of distilled water. The boxes were arranged in germination chamber (B.O.D.) with constant temperature of 25°C receiving 16 hours from illumination and 8 hours without light per five days. The countings of the germinated seeds were done daily. The data of germination and germination speed index were submitted to analysis of variance and means test (Dunnett 5%). The seeds of lettuce, Regina variety, were stored per one year in cold chamber before artificial aging. It was applied 0.4 mL of each homeophatic preparation in 40.0 mL of distilled water in gerbox. After 72 hours, 41°C, in dark, the 100 seeds of 14 boxes were divided in five replications of 20 seeds and placed on a humidified germitest sheet of paper with 7.0 mL of distilled water in gerbox. The boxes were placed randomly in B.O.D. 20°C during six days and countings of germinated seeds were done daily. The data of germination and of germination speed index were submitted to analysis of variance and means test (Dunnett 5%). The sunn hemp seeds were revigorated by the effect of homeophatic preparations of gibberellic acid (1CH, 4CH and 11CH). The seeds of lettuce aged artificially received the information from the homeopatic chemical preparation through hot water steam and the vigor was preserved as an effect of gibberellic acid 11CH.
