EVALUATION OF EUCALYPTUS UROPHYLLA X EUCALYPTUS GRANDIS CLONES PLANTED IN TOCANTINS, AIMING AT QUALITY FOR ENERGY USE

Abstract

The world energy matrix has been questioned, as climate change, trends of decline in oil reserves, as well as political instability in producing regions have led the world to reflect on the need for important changes in its sources. Wood from planted forests presents itself as one of the solutions for a renewable source of energy. The objective of this work is to identify among the five clones of the hybrid of Eucalyptus urophylla x Eucalyptus grandis planted in Tocantins, those that produce satisfactory quality for energy use. The experiment was carried out according to a completely randomized design, with five treatments and four replications. The data were submitted to analysis of variance and, when differences were established between them, the Scott-Knott test was applied at 5% probability. The results confirmed that the five clones have adequate physical and energetic characteristics to increase energy quality. However, clones 2 and 3 stood out for presenting the best performances in the evaluations carried out.
