| Summary: | The expansion of agricultural areas over the Amazon biome and illegal logging has caused a reduction in forest areas and the risk of extinction of several native species. Thus, cultivation in agroforestry or monoculture systems is essential for the economic and environmental sustainability of the sector. For this, it is necessary to understand the physiological parameters of seeds and establish protocols that help growers and nurseries during the seedling production phase. The objective of this work was to develop methods to evaluate the germination of Amburana acreana seeds at different temperatures and photoperiods. The seeds were submitted to germination tests, germination speed and average germination time at constant temperatures of 25 °C, 30 °C, 35 °C and 40 °C and two photoperiods, 12 and 24 hours of light. The temperature of 40°C inhibited germination. The germination process of A. acreana seeds is favored with a temperature of 30 °C under 24 h of light, promoting up to 100% germination. |
