QUANTIFICATION OF PRODUCTION OF BIOMASS IN CLONES OF EUCALYPTUS WITH 4.5 YEARS IN THE POLE Plasterer ARARIPE-PE

Abstract

The aim of this study was to quantify the production and distribution of biomass in the different compartments of the aerial part of the tree (stem, leaves, twigs and bark), in an experiment in randomized blocks with 15 clones of eucalyptus grown at the Experimental Station of the Company Pernambuco-IPA Agricultural Research in Araripina-PE. 90 trees, which were determined in the fresh weights and collected samples of leaves, twigs, bark and wood to determine the average wood density and biomass were felled. The total biomass of aerial 15 Eucalyptus clones were determined, respectively, 62.08; 92.27; 70.27; 95.36; 104.75; 132.13; 119.35; 58.60; 107.06; 92.51; 109.93; 50.87; 61.17; 69.90; 93.76 t ha-1. By Scott-Knott test was no difference between the treatments of the components leaves, branches and trunk, as the production of biomass. As for the shell component no significant difference between treatments. The most and least productive in terms of biomass clones were treating 6 Hybrid Eucalyptus urophylla x E. tereticornis x E. pellita (controlled pollination) with 132.13 t ha-1 and the treatment of E. 12-111brido brassiana (crossing natural) to 50.87 t ha-1.
