Wood anatomical characterization and intraspecific variation in Protium apiculatum Swart at the second forest management cycle

Tapajos National Forest had their first cutting cycle conducted in 1979 and since then the area has been monitored through forest inventories. In this period there have been changes in floristic composition, with Protium apiculatum Swart being among the most abundant and frequent species, however, there are no studies of its wood’s technological characteristics. Thus, the study aimed to characterize anatomically five trees of that species. To this end, wooden disks were collected at a two meters height from each individual, from where we withdrew material for macroscopic and microscopic analysis. Through the results, it was noted that the anatomical characters of Protium apiculatum Swart are consistent with other species of its genus, and there is variation among the trees studied
