Abstract
ABSTRACT – Anything that can change the growth pattern of a tree may result in wood variation. The objective of silvicultural operations in to change growth patterns. One cannot predict the response of the tree as to wood properties from this change and the only way to tell for sure is to grow the trees under the extant conditions. Usually, added growth from nitrogen fertilization will decrease wood density in the hard pines while a similar amount of added growth from thinning levels the wood relatively unchanged. Fertilization can greatly affect the wood produced, as will drastic thinning. Differences in stocking density in plantations from initial planting has less effect. Pruning, if done correctly, generally has only a minor effect on wood other than the obvious increase in clear wood. Actually, almost any extreme silvicultural activity can alter the wood enough to have a real affect on the final products produced. This is especially true for exotic species when planted in their new and different environments. RESUMO – Qualquer coisa que consegue altera o padrão de crescimento de uma árvore pode resultar em variação na qualidade da madeira. O objetivo das operações silviculturais é mudar os padrões de crescimento. Em termos de propriedades da madeira, a resposta das
