The araçá-boi (Eugenia stipitata McVaugh, Myrtaceae) an Amazonian species, has fruits with agreeable aroma and flavour, and high pulp yield. This study evaluated physical and physiological seed qualities after hand and mechanical extraction, cleaning by friction with different materials (sand, sawdust, sand+sawdust, hydrated lime, on a sieve, and without friction) and cleaning by natural fermentation (with and without change of water every 0, 1, 2, 3, 4 c 7 days). The mechanical method allowed extraction of the largest quantity of pulp (78% of weight and 81% of fruit volume). Friction with hydrated lime gave the highest percentage (98 %) and germination speed (0,989). Under natural fermentation, keeping the same water for more than one day negatively affected the physiological quality of the seeds. |
