O objetivo do presente trabalho foi determinar a embalagem e a temperatura adequadas para o armazenamento de sementes de carolina. As sementes foram armazenadas em sacos de papel e de plástico, mantidas em 0±2; 10±2; 20±2°C e 60 5% de umidade relativa do ar (UR) e em temperatura ambiente (23,4±3,3°C) e 68,7±9%UR. O teor de água, a germinação e o vigor foram determinados trimestralmente. Durante o armazenamento, o teor de água das sementes foi de aproximadamente 8,9%. A embalagem saco de plástico e a temperatura de 0°C são adequadas para o armazenamento das sementes de carolina.<br>The objective of the present research was to determine the more adequated packing and temperature for storage of "carolina" seeds. The seeds were stored in paper and plastic packings and kept in 0±2; 10±2; 20±2°C and 60 5% air relative humidity (ARH) and in ambient temperature (23,4±3,3°C) and 68,7±9% ARH. Quarterly, the water seed content, germinative test and seed vigour were avaluated. During storage, the seed water content was approximately 8.9%. The plastic packing (plastic bag) and tempertature of 0oC are adequated for storage of "carolina" seeds.
