Vigor das sementes de Apeiba tibourbou Aubl. sob difrentes condi??es de armazenamento e embalagens.

摘要

This study had the objective of evaluating the vigor of Apeiba tibourbou seeds submitted to different storage and packaging conditions, during 225 days. After processing, the Apeiba tibourbou seeds were conditioned in the following packages: transparent glass containers, Kraft paper bags and transparent polyethylene bags and stored under the following conditions: room temperature in a laboratory (24.8oC to 28oC; UR 68.9 to 82.5%), in a freezer (-20oC; UR 90%) and in a chamber (18.5 ± 1oC; UR 71 ± 3%). At the beginning and every 45 days, during 225 days of storage, the seed moisture content was determined and a vigor test was carried out (percentage and index of speed of emergence, length (cm) and dry weight matter (mg) of seedling). Among the storage conditions studied, the most suitable for conservation of Apeiba tibourbou seeds for 180 days, with less loss of vigor was the natural environment of the laboratory, when using the polyethylene bag packaging.
