Embebição e germinação de sementes de camu-camu = Imbibition and germination of camu-camu seeds

Abstract

Objetivando verificar o comportamento das sementes de camu-camu, quanto à germinação, em função da embebição, realizou-se o presente trabalho, utilizando-se sementes extraídas de frutos maduros, provenientes de plantas adultas. Os tratamentos consistiram em seis tempos de pré-embebição: 0 (testemunha), 4, 8, 12, 24 e 36 horas. Após cada período, as sementes foram colocadas em caixas tipo gerbox, tendo como substrato vermiculita textura fina, e mantidas em germinadores BOD à temperatura constante de 25ºC. Para cada tratamento foram realizadas 4 repetições com 25 sementes cada. Realizaram-se avaliações diárias do número de sementes germinadas, sendo os dados agrupados semanalmente e transformados em arc sen x / 100 para fins de análise estatística. As médias foram comparadas pelo teste de Tukey, a 5% de probabilidade. Pelos resultados obtidos, pode-se concluir que a germinação das sementes de camu-camu não é influenciada pela embebição, bem como pelo período deste tratamento.This research was carried out aiming to verify the behavior of camu-camu seeds in their germination, according to imbibition periods. The seeds were extracted from ripe fruits of old plants. The treatments consisted of six preimbibition periods: 0, 4, 8, 12, 24 and 36 hours. After each period, the seeds were placed in gerbox, having vermiculite as substrate. They were maintained in a temperature of 25oC, in a germination chamber (BOD type). For each treatment, 4 replications with 25 seeds in each one were accomplished. Daily evaluations of the number of germinated seeds were done. The data were grouped weekly and they were transformed in arc sen x / 100 . The means were compared by the Tukey test (5% probability). Results showed that the germination of camu-camu seeds is not influenced by the imbibition, as well as by the period of this treatment.
