Se evaluó las características anatómicas, variación radial y longitudinal de los constituyentes anatómicos de Calycophyllum spruceanun (Benth). Hook., de una plantación procedente de la Amazonía peruana. Se utilizaron seis árboles, de ellos se colectaron 3 discos de cada árbol (base, DAP, ápice); de cada uno se consideró tres posiciones en dirección medula-corteza y tres posiciones en dirección base-ápice. Se describieron las características anatómicas de la fibra y elementos de vasos y radios. Se encontró que la longitud de fibra, espesor de pared, diámetro tangencial de poros y longitud de vasos aumentó de manera significativa hacia la corteza; mientras que la frecuencia de poros disminuyó. En sentido longitudinal, la longitud de fibras y longitud de vasos, disminuyó de manera significativa hacia el ápice; la frecuencia de poros aumentó hacia él; la pared de fib...

The present study aimed to determine the physical and mechanical properties of a 20-year-old plantation of the species Calycophyllum spruceanum, known in Peru as “capirona,” for its potential for wood flooring production. For this purpose, samples were collected from six trees in a plantation located in the district of Curimaná, department of Ucayali, Peru. Physical and mechanical property tests were conducted following the American Society for Testing and Materials (ASTM) D143-94(2000) standard. The results showed that capirona has a basic density of 0,68 g/cm3, which is considered a heavy wood, and exhibits moderate dimensional stability. The mechanical properties demonstrated that the wood has a high resistance to bending and compression parallel to the grain, and a very high resistance to compression perpendicular to the grain, hardness, shear, and toughness. Based on the Peruvi...

[The aim of this study was to determine the physical-mechanical properties of a 20-year-old plantation of the species Calycophyllum spruceanum, known as "capirona" in Peru, due to its potential in wood flooring production. Samples were taken from six trees in a plantation in Curimaná-Ucayali, Peru, and tests were conducted according to ASTM standards (ASTM D 143-94 – 2 000). The results revealed that capirona has a basic density of 0.68 g/cm3, categorizing it as heavy wood, with moderate dimensional stability. Mechanical properties indicated high resistance to bending and parallel compression, and very high resistance to perpendicular compression, hardness, shear, and toughness. According to NTP 251.135.2013, capirona wood was positively evaluated, highlighting its potential for the production of solid wood flooring].
