Conteúdo:  Loblolly pine (P. t'asda L.), a species of high commercial value, has a wide geographic range and grows under many different site and environmental conditions. Its morphological and physiological characteristics have been observed in a general way to vary considerably, both regionally and locally, throughout its natural range. The observed variation has led to both speculation and effort concerning the possibility of finding and breeding improved strains of loblolly pine. The feasibility of breeding trees for wood properties has been discussed without much unanimity for many years. Scome have expressed opinions similar to KOEHLER'S (1939) that wood is a,, conservative character," and that it gives small hope for discovering pronounced inherent wood differences between varieties, races and strains of a species. Others have been more optimistic about breeding for wood properties and have looked forward to the time when,, strains" with special wood could be developed (SCHREI-NER, 1935). SCHÜTT (1959) analyzes briefly the potential development of trees with different woods through natural selection. One thing is clear, however;-before genetic studies of wood properties can be efficiently undertaken, the variation pattern from tree to tree, site to site, as well as throughout the range of the species, must be known. In addition, the interrelationships among the various wood characteristics and growth factors need to be determined. The present study was initiated to determine the ... Mostrar Tudo
