Abstract

Wild strawberry (Fragaria vesca L.) is an important source of genetic diversity which, on the other hand, has its propagation by seeds difficult due to the integumentary dormancy of the achenes. This study evaluated the effects of different doses of the GA₃ regulator and times of chemical scarification with sulfuric acid on the in vitro germination of F. vesca. The experiment was carried out on the premises of the State University of Tocantins using five doses of GA₃ (0mg.L⁻¹, 1mg.L⁻¹, 1.5mg.L⁻¹, 2mg.L⁻¹ and 2.5mg.L⁻¹ ) and four scarification times (0, 1, 5, 10 and 15 minutes), with in vitro cultivation of the seeds on the modified MS medium. The parameters evaluated included the Germination Speed ​​Index (GVI) and Germination Percentage (PG), with analysis by ANOVA and Tukey's test at 5% significance. The results showed that gibberellic acid, at the doses tested, was not effective in inducing the germination of F. vesca achenes. However, scarification of achenes with H₂SO₄ for 10 minutes, for all doses of GA₃, was effective in increasing IVG, concluding that this chemical scarification time is more efficient to overcome dormancy of Fragaria vesca achenes. Chemical scarification was enhanced with the use of GA3.
