Taper functions to describe the stem profile and total bole volume for Pinus ca...
Silva, Fernando da; Dalla Corte, Ana Paula Aula; Sanquetta, Carlos RobertoThe aim of this study was to evaluate the accuracy of taper functions for estimating diameters along the stem according to diameter classes and total volume. Studied was Pinus caribaea var. hondurensis in the Triangulo Mineiro region, state of Minas Gerais. The database consisted of 200 trees measured by the method of Hohenadl with ten sections, randomly chosen based on age and diameter distribution. The ages o...
Biomass expansion factor and root-to-shoot ratio for Pinus spp. in southern Brazil
Dalla Corte, Ana Paula Aula; Silva, Fernando da; Sanquetta, Carlos RobertoBiomass expansion factor (BEF) and root-to-shoot ratio (R) are variables for quantification of carbon in forests. These are considered as constant values in most studies. 70 sample trees were used to BEF and R, and DBH, tree height and age. Dry total biomass, carbon and CO2 equivalent were simulated by using the IPCC default values of FEB and R, corresponding average calculated from data using in this study and...
Biomass expansion factor and root-to-shoot ratio for Pinus in Brazil
Sanquetta, Carlos Roberto; Dalla Corte, Ana Paula Aula; Silva, Fernando daThe Biomass Expansion Factor (BEF) and the Root-to-Shoot Ratio (R) are variables used to quantify carbon stock in forests. They are often considered as constant or species/area specific values in most studies. This study aimed at showing tree size and age dependence upon BEF and R and proposed equations to improve forest biomass and carbon stock. Data from 70 sample Pinus spp. grown in southern Brazil trees in ...
