Conteúdo:  A review of possible changes in wood morphology through genetic manipulation of the southern pines showed that: 1.Significant changes can be obtained by modifying tree form, growth rate and disease resistance. (a)Compression wood can be reduced by developing straighter trees. The inheritance of straightness is so strong that one generation of selection has resulted in enough improvement to enable deemphasis of this characteristic in second-generation breeding. (b)Branch size affects the final product by knot volume and the associated compression wood, included bark and resin; it is moderately genetically controlled. (c)Use of disease-resistant trees not only results in greater wood volume but in higher quality wood. Logs infected with fusiform rust give lower pulp yields and lower mullen and tensile strength in the paper. (d)Growth rate has a limited effect on wood qualities in mature loblolly pine. It is possible to have fast growth combined with either high or low specific gravity wood, since these characteristics are not closely related genetically. 2.Inheritance of wood qualities per se is strong enough to obtain meaningful changes in both yield and quality of pulp and paper. (a)Wood specific gravity, which is really a complex of several characteristics, has responded well to selection. Specific gravity differences affect yield, quality and cost from harvesting to the end product. (b)Cell wall thickness appears to be the most important morphological characteristic that a... Mostrar Tudo
