Resumo: The use of biomass as an alternative energy source has been gaining attention because of its energy characteristics and environmental contribution and because it is renewable in short production periods. The aim of the present study was to evaluate the biomass production and carbon sequestration of eucalyptus grown under different conditions. The basic density of the wood, stem volume with and without bark and dry biomass, accumulated carbon, assimilated carbon dioxide and estimated energy for each shoot component were determined for two hybrid clones of E. grandis x E. urophylla at 6 and 12 months of age, grown at different spacing in two different areas, one with and one without irrigation. The highest dry biomass and carbon accumulation values were observed for plants grown at smaller spacing and with irrigation. A significant effect of irrigation on the variables quantified was only observed for 12-month-old plants. The amount of assimilated CO2 in the stem, leaves and branches was higher for 12-month-old plants grown at larger spacing and with irrigation. The estimated energy of the stem increased with increased spacing. Bark was the shoot component least influenced by spacing and irrigation.

O trabalho objetivou avaliar a produção da biomassa e sequestro de carbono de eucalipto em diferentes condições de crescimento. Foram determinadas a densidade básica da madeira, volume individual com e sem casca, biomassa seca, carbono acumulado, dióxido de carbono assimilado e estimativa energética dos componentes da parte aérea de dois clones do híbrido de E. grandis x E. urophylla aos 6 e 12 meses de idade, em diferentes espaçamentos e provenientes de duas áreas, uma irrigada e outra não irrigada. Os maiores valores de biomassa seca e massa de carbono foram provenientes dos clones nos espaçamentos mais adensados e região irrigada. O efeito da irrigação foi significativo nas variáveis estudadas apenas nos clones com 12 meses. A quantidade de CO2 assimilada no fuste, folha e galho foram maiores nos espaçamentos mais amplos e região irrigada dos clones com 12 meses. A estimativa energética do fuste aumentou com a ampliação do espaçamento. Entre os componentes arbóreos, a casca sofreu menor influência dos espaçamentos e irrigação.Universidade Federal de Lavras (UFLA)2016-12-232017-08-01T20:17:05Z2017-08-01T20:17:05Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfMAGNAGO, L.
