Quality assessment of jabuticaba seeds when subjected to different temperatures

Abstract

Jabuticaba is a typically Brazilian fruit, which can be found from the extreme south to the extreme north of the country, it can be used for various purposes, its commercialization ranges from in natura, industrial, pharmaceutical and cosmetics. In view of the above, this work aims to evaluate the influence of the size of jabuticaba seeds of the rajada variety, its germination potential, total seedling size, root and shoot length and seedling emergence, using different treatments. The extraction of the seeds was carried out by manually kneading the fruits against a flat and firm surface of a bench, so that they broke and exposed their seeds, soon after the mucilage was removed manually as well. After pulping, disinfestation was carried out using 1% sodium hypochlorite for three minutes, then triple washing with distilled water and arranged on paper towels, where they remained for 48 hours in the shade to remove excess moisture, separated according to diameters. To seeds to carry out the germination tests and the emergence speed index, when submitted to different treatments. In which it can be concluded that the size of the seed increases the germination potential of jabuticaba seeds, where larger seeds originate more vigorous seedlings, and should preferably be used for seedling production. The best treatment is the refrigerated one with a temperature of 5°C, as it presented a greater amount of seedlings throughout the days.
