Item Caracterização energética da madeira de quatro clones de Eucalyptus plantados em Pernambuco(2024-03-08) Araújo, Juliana Cristina Rodrigues de; Braz, Rafael Leite; http://lattes.cnpq.br/7332493832361305; http://lattes.cnpq.br/4227532833595437Brazil's main energy matrix is hydroelectric plants, however, not all regions are able to achieve the desired energy supply rates, so the search to diversify the energy matrix using the available resources of each region is on the rise. The Brazilian energy matrix has always used forest biomass to be able to meet part of the demands, with charcoal and firewood as the main use. Thus, the present work aimed to carry out the energetic characterization of the wood of four clones of Eucalyptus, being the hybrids E. urophylla x E. grandis and the (E. camaldulensis x E. grandis) x E. Urophylla, both six years old, collected in the municipality of Paudalho in the Zona da Mata of Pernambuco and two clones of Eucalyptus urophylla with eight years of age, from an experimental plantation located at the Experimental Station of the Agronomic Institute of Pernambuco (IPA) in the Araripe plateau, municipality of Araripina – PE. The analyses were conducted at the Wood Technology and Anatomy Laboratory of the Department of Forest Science of the Federal Rural University of Pernambuco - UFRPE, where the content of volatile materials, ashes, and fixed carbon of the wood was determined according to ASTM standards. Based on the values of the variables obtained, the upper, lower and useful calorific value were estimated. Data were submitted to Tukey's test (p = 5%) to compare means. According to the results obtained, the clones did not show any difference in relation to the analyzed variables, so all of them would be a viable alternative energy matrix for the region. It is recommended to study other properties of the wood, including the energetic ones, as well as the growth variables of the material, seeking to obtain more information to select the best genetic material for the production of biomass for energy in the region.Item Zoneamento agroclimático para plantio de Eucalyptus urophylla na Zona da Mata de Pernambuco(2024-02-19) Silva, Carlos Antônio Campelo Cavalcanti; Silva, Emanuel Araújo; Almeida, Débora de Melo; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/1534900496128952The state of Pernambuco, encompassing the biomes of the Atlantic Forest and Caatinga, faces challenges of degradation, especially in the Atlantic Forest, extensive sugarcane cultivation has resulted in forest fragmentation of biome, with impoverished and abandoned areas. The study suggests reestablishing the use of these degraded areas considering market demand, with the main objective of conducting an agroclimatic zoning of areas suitable for eucalyptus plantation in the Zona da Mata of Pernambuco. To achieve this, data on average air temperature and precipitation were collected from four meteorological stations distributed in the region. Using these data, monthly climatic water balance was calculated following the method proposed by Thornthwaite and Mather (1955). Subsequently, the data were processed and mapped using a Geographic Information System (GIS) environment using QGIS 3.16 software. The agroclimatic zoning was elaborated considering the climatic requirements of the Eucalyptus urophylla species, highlighting areas with thermal and water conditions suitable for cultivation. The results showed that approximately 28.95% of the analyzed territory in the Zona da Mata is suitable for the development of the species, concentrating in 16 municipalities surrounding the Metropolitan Region of Recife. This potential area totals 2428 km². On the other hand, approximately 71.05% of the studied area was considered unsuitable due to identified levels of water deficit. These results can contribute to land use planning, promoting more sustainable and effective cultivation practices in the region.
