- Abstract
This study aimed to verify the seeds germination of araticum plant depending on gibberellin application. The experiments were carried out at the Federal University of Paraná, Curitiba City, Paraná State-PR, Brazil, with seeds from Santo Antônio do Leverger municipality, Mato Grosso-MT, Brazil. Two successive experiments were performed with application of different concentrations of gibberellic acid (GA3) in which the variables of the first count, percentage, and index of germination speed (IGS) were considered. Was observed germination of 30-59% in the first count and 71-86% in the germination test with IGS ranging from 0.38 to 0.48 for treatments with GA3 in experiment 1; in experiment 2, it was found germination of 15-41% in the first count and 26-59% in germination test with IGS ranging from 0.11 to 0.28 with application of GA3. It is concluded that seeds of araticum plant have physiological dormancy easily overcome by the application of GA3.
