Avaliação do encapsulamento de sementes recalcitrantes de Campomanesia adamantium (Cambess) O. Berg

Abstract

The gabirobeira (Campomanesia adamantium) is a fruit species of the Cerrado, its fruit presents commercial potential in the in natura consumption and in the food industry. However, gabiroba seeds have recalcitrant behavior. Species with this type of behavior can be conserved by means of tissue culture techniques of plants, such as, for example, synthetic seeds. The objective of this work was to establish the protocol for the production of synthetic seeds of Campomanesia adamantium from true seeds. For the encapsulation of the seeds, 4 concentrations of sodium alginate (0.1.5, 2 and 3%) and 3 complexation times (15, 20 and 30 minutes) were tested, with no significant interaction between the studied factors, however. As the alginate concentration increases the germination time increases and the germination capacity decreases. Synthetic seeds with the same concentrations of alginate were produced in 20 minutes of complexation and stored at 4 ° C for 1, 7, 15, 30 and 60 days in order to evaluate the storage capacity of the same. The concentrations of 2% sodium alginate were able to preserve the integrity of the membranes of the encapsulated seeds regardless of storage time, however this was not enough to promote germination.
