Abstract
Context: Forest plantations are a sustainable alternative for meeting the demand for timber products and ecosystem services.
Objective: To estimate the growth in diameter at breast height, commercial volume, and carbon sequestration of Calycophyllum candidissimum (Vahl) DC. using dasometric and morphometric variables in plantations aged 7 to 10 years.
Methods: Logarithmic regressions were applied using age as an independent variable. Biomass and carbon were estimated using validated allometric equations. Statistically significant differences in variables between ages (p < 0.001), and correlations (p < 0.05) were analyzed using tests based on data normality.
Results: Slenderness suggests low structural resistance to climatic events and higher timber yield. Principal component analysis explained 82.90% of the variability, differentiating crown morphology and stem growth. The regression models for estimating tree growth had moderate coefficients of determination (R2 < 0.62), but were statistically significant (p < 0.001) and met the analysis assumptions. Carbon capture ranged from 10.47 to 55.87 t ha-1, with 88% accumulated in the aerial fraction, equivalent to 38.42 and 205.02 t ha-1 of CO2, respectively.
Conclusions: Morphometric variables show dominant vertical growth in the crown. It is recommended to expand the range of ages studied for a better understanding of tree growth and to incorporate site studies to optimize silvicultural management in the region. C. candidissimum can be considered a viable species for carbon sequestration and voluntary markets.
