Germination of seeds and seedling quality of Plinia trunciflora under different pre-germinative treatments.

Abstract

The formation of forest seedlings of good morphophysiological quality involves processes of seed germination, which in turn is dependent on genetic potential. Some actions in the pretreatment of seed germination can help. This study aimed to evaluate the germination and initial quality of seedlings under different treatments jabuticaba pre-germinated: T1 - seeds thoroughly cleaned; T2 - seeds oxidized with the fruit macerate; T3 - pulp with seeds, and T4 - the fruit with seed sowing. The experiment was conducted during the period from October 2007 to August 2008. The experimental design was a completely randomized with four treatments in 4 replicates. It was calculated of the percentage of germination at 40, 60 and 90 days, and the analysis of the index emergency speed at the end of the period. At 306 days after sowing they were assessed the morphological parameters of seedlings, their relationships and quality index of Dickson for seedlings. It has been proved that the seeds thoroughly cleaned and cored joined with the previous treatments were the most effective in the process of germination and seedling quality.
