| Abstract | This work aimed to evaluate the behavior of two eucalypt clones in areas with different rainfall on productivity and quality of wood at ages 24, 48 and 72 months. This study compared two genetic materials, represented by hybrid clones urograndis, being one less productive (P-) and other more productive (P +), in three ages and two environmental conditions. The wood samples were collected from two areas with different climatic conditions in the south of Bahia. In each area were the samples collected from two clones in three different ages (24, 48, and 72 months), taking six plants per repetition. In each plant were discs removed at 0, 25, 50, 75 and 100% commercial tree height to determine the Specific Mass (ME) and Power Calorific Value (PCS). The ME was determined by removing the two sampled wedges diametrically opposite of each disk, and the PCS was determined with sawdust taken with the unused part of the disk. The Dry Mass (MS) per hectare was calculated with the values of Mean Annual Increment (IMA) and ME, and energy per hectare was calculated on the basis of the values of PCS and MS of wood. The results showed that the clone P + showing the highest potential for biomass production and energy per hectare, but the clone P-showed the biggest trends of gross calorific value and density, verifying that the clone that features the best production conditions is not always the same as that gives the best characteristics of wood to be used as energy. On the other hand, the area east despite having the highest water availability throughout the year, the highest biomass productivity and energy per hectare was shown in the area with higher water restriction. So for achieve higher productivity and wood quality is more important to the selection of genetic material that the location of the area, but without disparaging the influence of environmental conditions about the genetic potential of each material. |
