Loddiges ex Mart. Dehydration was performed in a forced-air oven at 37 ± 2°C for 0, 3, 6, 9, 12 or 15 days, and after these periods, the embryo viability was evaluated by the tetrazolium test. The effect of hydration on the germination percentage and velocity index was evaluated by the imbibition of seeds with distilled water in a germinator at 30 ± 2°C for 0, 2, 4, 6, 8 or 10 days. The seeds we re then treated with fungicide and maintained in a Mangelsdorf germinator at 30 ± 2°C. Drying caused a pr ogressive water loss in the fruits and facilitated the extraction of the seeds. Fruits subjected to drying for up to nine days had no loss of vigor; however, after dehydration for 15 days, a loss in seed viability was ob served. Simple linear regression estimated the seed water content based on the fruit water content. Seed imbibition in distilled water favored an increase in dead by fungally contaminated seeds. 2012 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303026599009 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
