Abstract : Primavera (Roseodendron donnell-smithii syn Tabebuia donnell-smithii) is one of the species most frequently exploited in the tropical zone of Chiapas, México, and research about it is required to ensure its conservation and use. Forest seeds are the main source of germplasm and the material most frequently used in commercial plantations, for which seeds with minimum characteristics of physiological, genetic, physical and sanitary quality are required. The objective of this study was to analyze some quality tests of seeds from trees that are candidates to be parent trees through viability, germination, weight and storage tests. The variables were evaluated at 15, 45, 75 and 105 days after collection. The conditions of storage were at room temperature and refrigeration at 8°C in resealable plastic containers. The physical purity was 85.5%, the number of seeds kg-1 was 248,200. The greatest percentage of viability (61%) was found during the first fifteen days, although germination increased as time went by until reaching the maximum at 75 days after their collection.
