Clonal selection of Corymbia for energy and charcoal production

Abstract

The genus Corymbia appears as an option to produce best quality charcoal. The selection of genotypes through multivariate analysis can be a solution when multiple variables influence the result. The aim of this study was to characterize eight genotypes of Corymbia citriodora x Corymbia torelliana for energy and charcoal production, group and indicate the genetic materials with highest potential. The woods specific gravity, high heating value and energy density was determined. Energy density was grouped by the Scott-Knott test; group 1 was appointed for energy generation. The wood was carbonized. Charcoal yield, density, fixed carbon, friability, higher heating value, ash content, fixed carbon yield and energy density were determined. Principal component analysis was performed. Principal component 3 was chosen, as the representation of the ideal genetic material. The scores were calculated, and genetic materials III, VI and VIII are selected for charcoal production. The selection has shown to be efficient.

Enraizamento in vitro e aclimatização de plântulas de Corymbia citriodora

“…Espécies pertencentes ao gênero Corymbia, e alguns de seus híbridos interespecíficos, assumem fundamental importância no setor florestal, principalmente pela adaptação a diferentes condições ambientais e pelos múltiplos produtos que podem ser obtidos (Trueman et al, 2018;Avelar et al, 2020). A busca por melhor qualidade do produto final, aumento da produtividade, resistência a pragas, doenças e distúrbios climáticos, além da expansão de cultivo em regiões não tradicionais, despertou o interesse das empresas florestais em incluir espécies e híbridos de Corymbia nos programas de melhoramento genético (Teixeira, 2015;Peres et al, 2019). Dentre as espécies, destaca-se Corymbia citriodora (Hook.)…”

Water flow in different directions in Corymbia citriodora wood

“…Corymbia wood in Brazil is mainly used in the energy, charcoal (Peres et al 2019) and treated wood (Lopes et al 2018) industries. Improved permeability in wood may lead to faster, cheaper and high-quality drying, improve the energetic use of wood, ease chemical treatment, and effectively manufacture wood-polymer composites.…”
