Dormancy is a mechanism found in several plant species developed through evolution, which allows plants to survive in adverse conditions and ensure their perpetuation. This mechanism, however, can represent a barrier that can compromise the development of the species of interest, and therefore, the success of its cultivation. It is important to understand the causes,…
