The increasing demand for native forest seeds has driven research on storage techniques that preserve viability and vigor. This study evaluated the behavior of Handroanthus chrysotrichus seeds stored in three environments: cold chamber (±11 °C), refrigerator (±2.5 °C), and bench (±25 °C), using polyethylene terephthalate (PET) bottles as containers. Germination Percentage (GP), Mean Germination Time (MGT), and Germination Speed Index (GSI) were analyzed every 60 days over a 300-day period. The results showed that storage in the refrigerator preserved seed viability throughout the experimental period, while the cold chamber maintained germination only up to 120 days and the bench environment showed total loss of viability after 60 days. The study reinforces the importance of low-temperature storage for preserving the quality of native forest seeds.
