    Abstract Path analysis has been used for establishing selection criteria in genetic breeding programs for several crops. However, it has not been used in eucalyptus breeding programs yet. In the present study, we aimed to identify the wood technology traits that could be used as the criteria for direct and indirect selection of eucalyptus genotypes with high energy density of wood. Twenty-four eucalyptus clones were evaluated in a completely randomized design with five replications. The following traits were assessed: basic wood density, total extractives, lignin content, ash content, nitrogen content, carbon content, hydrogen content, sulfur content, oxygen content, higher calorific power, holocellulose, and energy density. After verifying the variability of all evaluated traits among the clones, a two-dimensional correlation network was used to determine the phenotypic patterns among them. The obtained coefficient of determination (0.94) presented a higher magnitude in relation to the effect of the residual variable, and it served as an excellent model for explaining the genetic effects related to the variations observed in the energy density of wood in all eucalyptus clones. However, for future studies, we recommend evaluating other traits, especially the morphological traits, because of the greater ease in their measurement. Selecting clones with high basic density is the most promising strategy for eucalyptus breeding programs that aim to increase the energy density of wood because of its high heritability and magnitude of the cause-and-effect relationship with this trait.

    Abstract Lignocellulosic wastes from Amazonian crops are promising for the production of biochar. However, there are scientific gaps concerning the thermodegradation mechanisms of widely diverse biomass. This research explored the relationships between the chemical compounds and the pyrolysis behavior of the açai seed, cocoa pod husk, coconut husk, palm empty fruit bunch, and maize cob by thermogravimetric analysis. The cocoa pod husk and palm empty fruit bunch showed the lowest temperatures of initial degradation (≤ 230 °C) because of the highest proportions of total extractives (≥ 17% dry basis) and ashes (≥ 5.7% dry basis) combined with the lowest contents of holocellulose (≤ 56% dry basis). Biomasses with higher extractives contents showed pronounced mass losses at temperatures ≤ 300 °C. The maize cob, with more holocellulose (68% dry basis), revealed a high maximum rate of thermal degradation of 7.9% min⁻¹ and mass loss between 200 and 400 °C of 65.6% wet basis. The high level of acetone-soluble extractives raised the temperature necessary for the initial thermal degradation of açai seed. The coconut husk, açai seed, and cocoa pod husk were the most suitable wastes for the production of biochar based on the average mass yields (≥ 41% wet basis) at the pyrolysis final temperature of 400 °C.

    Abstract Charcoal for domestic use presents great variation in quality because in most furnaces the carbonization process is difficult to and often inadequate raw material is used, generating a heterogeneous product. Near infrared (NIR) spectroscopy is a fast and reliable method to classify bio-based materials. Thus, the aim of this study was to apply NIR spectroscopy coupled with multivariate statistics in order to classify commercial vegetable charcoal for domestic use into categories and estimate its quality. Seventy-six charcoal specimens from nine producers were selected for NIR spectra acquisition on the transverse (TV) and rolling surface (RS) using the integrating sphere and fiber optic probe on raw (untreated) and sanded charcoal. Principal Component Analysis (PCA) of the spectra was performed to verify possible clusters among producers or quality classes (in terms of FCC levels). Discriminant Analyses based on Partial Least Squares (PLS-DA) were performed to classify the charcoals according to their producers and to predict their quality class. The PCA of spectra was not able to distinguish groups indicating high heterogeneity between treatments. However, PLS-DA models correctly classified up to 95% of the charcoal specimens both by producers and quality classes using spectra obtained by the integrating sphere or fiber optic probe. NIR spectroscopy coupled with multivariate analyses presented potential to be an efficient and rapid technique to classify charcoal. PLS-DA models can be applied in unknown charcoal specimens for reliable classification.
