Avaliação Da Produção De Biomassa Do Fuste De Um Clone Híbrido De Eucalipto Sob Diferentes Espaçamentos

Abstract: RESUMOO uso de florestas de Eucalyptus tem se tornado cada vez mais expressivo no Brasil, sobretudo por conta da excelente produção em termos volumétricos por elas alcançadas e pelas boas características da madeira obtida. O presente trabalho teve como objetivo identificar os melhores espaçamentos de plantio para florestas clonais de um híbrido interespecífico de Eucalyptus grandis e Eucalyptus urophylla, de forma a maximizar a produção de biomassa do fuste por hectare buscando a área vital por árvore em um in… Show more

“…By observing the results in Table 3, we see the parameters of the evaluated models are not null since the confidence intervals do not include zero, thus indicating quality in their estimation. The estimates of the α parameter were very close for the Gompertz, Logistical and von Bertalanffy models, whereas the Brody model presented a value above the others, which can also be found in the studies conducted by Oliveira et al (2000) and Ribeiro et al (2017).…”

“…Analyzing the growth pattern in forest studies is usually by regression models means. Some authors found a sigmoid behavior in the growth of trees, leading them to employ nonlinear regression models (Ribeiro et al, 2017;. In this case, these models are more appropriate than the linear ones in describing the biological processes, since they are generally more parsimonious and have parameters with practical interpretations (Sousa et al, 2014;Archontoulis & Miguez, 2015).…”

“…The volume of the trees was obtained from measurements of the diameter along the stem, from the cutting base to the minimum diameter of 7 cm. The formula proposed by Smalian was used, where the volume of each section of the tree was estimated, for later obtaining the total volume (Ribeiro et al, 2017). Then the average volume of trees harvested was multiplied by the number of trees per hectare.…”

“…For the volume calculation, measurements were made every meter of the stem, from the cutting base of each tree to the minimum diameter of 7 cm. The volume of each section was calculated according to the formula proposed by Smalian, obtaining the total volume of each tree by adding the values of each section (Ribeiro et al, 2017).…”

“…Though studies have evidenced the need of more complete analysis of the inherent characteristics of feedstock in the selection of superior genetic materials, contemplating variations existing in wood properties, in the anatomical, chemical and physical structure, besides the variables of the carbonization process (Pereira et al, 2013b;Santos et al, 2016;Ribeiro et al, 2017;Rocha et al, 2017).…”
