Eucalyptus grown in elevated regions of southern Brazil differs from other regions of thecountry that produce this crop, because of the limited amount of genetic materials that arecommercially available. Because germplasm always must be prepared to withstand frequentfrosts from intense cold fronts in order to provide wood for various utilities, there are limitedoptions for supplying this raw material from planted forests. Thanks to initiatives by EmbrapaFlorestas in past decades (principally the 1980s and 1990s), various test units containinggenetic material from subtropical eucalyptus were installed at the Celulose Irani corporation inSanta Catarina. This research is intended to obtain advances in productivity and quality forfuture eucalyptus plantations that will be planted in the region where this company works, aswell as other areas with similar climate and soil conditions. This project will obtain and providecultivars, seeds, and clones of Eucalyptus badjensis and Eucalyptus viminalis to permit theimplantation of forest plantations that will produce wood to meet energy and industrial needsin regions that experience intense cold.
