Importance of Pits in Corymbia Citriodora (Hook.) K.D. Hill & L.A.S. Johnson (Myrtaceae) Wood Permeability

Abstract

Aim of this research was to evaluate the relationship between the biometrics of vessel-ray pits (RVP) and intervessel pits (IVP) with the water flow in different axes of Corymbia citriodora wood. C. citriodora wood specimens were used to correlate RVP and IVP dimensions with free water (FWFR), adsorbed (AWFR) and total (TWFR) flow. Correlations were made for three wood axes. Larger diameters of RVP facilitated FWFR, AWFR and TWFR in axial and tangential axis, however reduced permeability in radial direction of wood. Larger openings of IVPs reduced FWFR, AWFR and TWFR in axial axis of wood. Larger IVPs openings allowed higher FWFR and TWFR in wood radial and tangential directions, however, concomitantly reduced AWR. Effect of diameter of RVP and IVP on wood permeability should be evaluated for each axis. Thus, the opening of the C. citriodora wood pits can interfere in its permeability and consequently in its processing.

Permeability of Parkia gigantocarpa as affected by wood anatomy

“…The increase in the frequency and diameter of vessels facilitate the water output from the wood (Siau 1984;Monteiro et al 2017). In addition, vessels have pits that communicate with ray cells or even other vessels, which also facilitate the air and liquid flow in the wood (Ahmed and Chun 2011;Monteiro et al 2021). Baraúna et al (2021).…”

“…The relationship between water and wood has been studied for at least a century (Engelund et al 2013); however, few studies evaluate the permeability of species native to the Amazon rainforest. Studying the influence of the technological properties of wood such as anatomical characteristics, e.g., number and diameter of vessels and fiber characteristics, may contribute to the better use of this wood as they are factors that influence the permeability of wood (Siau 1984;Ahmed and Chun 2011;Monteiro et al 2017Monteiro et al , 2021Panigrahi et al 2018;Jang et al 2020).…”
