“…Thus, variations in wood anatomic structure could affect its quality for construction, furniture production, pulp and paper, and fiber-based products. Thus, Rajput et al (2023) emphasized that the anatomical properties of wood, which can affect the density, type, and quality of pulp and paper produced, and the character of fiber-based products should not be overlooked, most especially concerning less-known (LKS) and lesser used timber species (LUS).…”

This paper presents significant findings on the variation in the anatomical properties of Anthocleista grandiflora wood, which could greatly influence its utilization in various products. Cubic-shaped heartwood and sapwood specimens were extracted at the base, middle, and top of boles from 38-, 43-, and 47-year-old trees. The variations in cell morphology and anatomical characteristics were meticulously assessed. The specimens were prepared into 3 mm x 10 mm fragments, macerated, and viewed under a microscope using Motic Image plus 2.0 ML software. The following parameters were determined: average values of fiber length, fiber diameter, lumen width, double fiber wall thickness, Runkel ratio, aspect ratio, coefficient of rigidity, and coefficient of flexibility of trees at the base, middle, and top. Notably, there were more vessels in sapwood than in heartwood, and the vessel areas increased with increasing vessel lengths. The results also revealed that in the heartwood region, the fraction of vessel lumen increases with tree age in the base, middle, and top sections. These findings are significant as they provide a comprehensive understanding of the anatomical properties of A. grandiflora wood, which is classified as wood from numerous vessels, a common characteristic of noble woods. The wood exhibited anatomical properties suitable for cellulose, paper, and fiber-based products, highlighting its potential in various industries. Keywords: wood quality; fibers; morphological characterization; timber industry. Variação das características anatômicas da madeira de Anthocleista grandiflora em função da idade e da posição no troco RESUMO: Objetivou-se avaliar as propriedades anatômicas da madeira de Anthocleista grandiflora e as suas possíveis aplicações. Amostras do cerne e alburno foram extraídas na base, meio e topo de árvores com 38, 43 e 47 anos de idade. Em seguida, foram avaliadas variações na morfologia celular e nas características anatômicas, por meio de fragmentos de 3 mm x 10 mm, macerados e visualizados em microscópio utilizando o software Motic Image plus 2.0 ML. Foram avaliados: comprimento da fibra, diâmetro da fibra, largura do lúmen, espessura da parede dupla da fibra, razão de Runkel, razão de aspecto, coeficiente de rigidez e coeficiente de flexibilidade das árvores na base, meio e topo. Verificou-se mais vasos no alburno do que no cerne, e as áreas dos vasos aumentaram com o aumento de seu comprimento. Os resultados obtidos também indicaram que na região do cerne a fração do lúmen dos vasos aumenta com a idade árvores nas seções da base, intermediária e topo, sendo os valores de 14.76, 11.38 e 20.73 mm para 38 anos; 23.74, 22.13 e 23.09 mm para 43 anos; 28.62, 12.89 e 25.01 mm para 47 anos. A A. grandiflora foi classificada como madeira de numerosos vasos, característica comum para madeiras nobres. A madeira apresentou propriedades anatômicas adequadas para celulose, papel e produtos à base de fibras. Palavras-chave: qualidade da madeira; fibras; caracterização morfológica; indústria madeireira.

This study looks into the effects of convective vacuum drying on the timber quality of Mangifera indica L. timber, focusing on drying rate, drying time, and mechanical, physical, and anatomical properties. Convective vacuum drying significantly reduced the moisture content of mango wood from 93.10% to 8–12% within approximately 99 hours, enhancing its physical and mechanical properties. The process yielded wood with no visual defects, increased basic density, reduced volumetric shrinkage, and improved mechanical strength metrics such as modulus of elasticity and rupture. Anatomical changes included reductions in vessel and fiber dimensions. The improvements observed suggest that convective vacuum drying is a useful technique for improving the quality of M. indica L. wood, increasing its suitability for a range of industrial uses.
