VIABILIDADE DE SEMENTES DE JABUTICABEIRA AÇU EM FUNÇÃO DA CONDIÇÃO E PERÍODO DE ARMAZENAMENTO

Abstract

The dim of this study was to evaluate the germination of jabuticaba açu [Plinia cauliflora (DC.) Berg] seed, according to remove the mucilage, loss of water content and the storage packaging. The experiment was carried out at UTFPR - Câmpus Dois Vizinhos, Brazil. The seeds were separated into two groups, with one it remained a mucilage surrounding the seed and without muncilage. The seeds with and without mucilage were put in Pet^® bottle, paper Kraft^® bag at natural condition temperature and paper Kraft^® bag in the refrigerator (6 °C ± 1 °C), which it was stored during 8 periods (0, 5, 10, 15, 20, 25, 30 and 60 days). After each period, the seeds were sown in Gerbox boxes without lid containing sand as substrate and it taken to BOD at 25 °C without photoperiod. The experiment was completely randomized in a factorial 2 x 8 x 3 (presence of mucilage x storage period x storage location), with 4 replications of 50 seeds each experimental unit. Recommend to remove the mucilage for further storage of jabuticaba seeds açu in Pet^® bottle at room temperature for a maximum of 25 days, without compromising the emergence and vigor.
