ABSTRACT Trees transport water from underground to the atmosphere through the evapotranspiration process. Climate change can significantly compromise this process due to changes in land use, such as deforestation. This study aimed to characterize the hydraulic and anatomical attributes of Jacaranda copaia (Aubl.) D. Don (Bignoniaceae), in the Southwestern Brazilian Amazon. For this purpose, the xylem vulnerability curve of this species was described. The frequency and diameter of the xylem vessels and the stomata density were also measured. Finally, a hydraulic attribute of Jacaranda copaia was compared to other species at global, tropical, and Amazonian levels. The findings show that, in the region studied, the species Jacaranda copaia has diffuse-porous woods and numerous vessels (average vessel ranging from 8 to 14 nº/mm2) with small ( |
