Conserva??o do vigor de sementes de pinha Anonna squamosa L.

摘要

Studies of suitable conditions on seed storage for each species are very important, because seeds stored under no-suitable conditions, lose their vigor. Thus, the present study aimed to evaluate the seeds vigor of sugar apple in five storage periods (0, 3, 6, 9 and 12 months), two storage conditions (noncontrolled environment and refrigerator) and two packaged (paper and plastic bags). The experiment was carried out in a factorial 5 x 2 x 4, in an entirely randomized design with 4 replications of 50 seeds. The moisture content was evaluated and vigor tests (percentage emergence, emergence speed index and seedlings dry matter) were performed. We concluded that the moisture content at 8.49% maintained the vigor of sugar apple seeds during the storage. Furthermore, we observed that seeds stored in plastic bags lost their vigor, while those stored in paper remained viable in non-controlled environment for six months.
