Germination of Annonas seeds - Breaking dormancy with gibberellic acid

This paper describes the effects of gibberellic acid (GA3) on the germination of three species of Annona, known as araticum-cagão, graviola and pinha. Their seeds are dormant, making germination more difficult. In order to solve this problem, gibberellic acid (GA3) was used, a type of gibberellin that, among other physiological effects, activates embryo growth and cancels the phenomenon of dormancy in some species. Analyses were carried out using standardised tests recommended in the Rules for Seed Analysis. It was not possible to establish a standard concentration for all Annona species, but each species responded positively to a certain concentration of GA3.
