Sequential Management of Commercial Rosewood (Aniba rosaeodora Ducke) Plantations in Central Amazonia: Seeking Sustainable Models for Essential Oil Production

Abstract

Rosewood (Aniba rosaeodora Ducke) is an endangered tree that produces essential oil of high commercial value. However, technical-scientific knowledge about cultivation is scarce and studies are needed to examine the management viability. The current study evaluated rosewood aboveground biomass management, measuring the export of nutrients resulting from harvesting and testing sustainable management models. The crown of 36 rosewood trees were pruned and 108 trees cut at 50 cm above the soil in two regions in Central Amazonia. Post-harvest performance of sprouting shoots was evaluated and after, sprouting shoots were pruned so that the development of two, three and all shoots was permitted. Nutrient stock estimation was calculated as the product of mass and nutrient concentration, which allowed nutritional replacement to be estimated. The pruning facilitates regrowth by 40.11% of the initial mass while by cut regrow 1.45%. Chemical attributes of regrowth biomass differed significantly prior to management and regrowth had a significant correlation with the reserves in root tissues and with the pre -management status of the individual tree. Driving sprouts resulted in significantly larger growth increments and may provide a form of management that can viably be adopted. Biomass sequential management resulted in high nutrient exports and the amount of fertilizer needed for replenishment depended on the intensity and frequency of cropping. Compared with the cut of the tree, pruning the canopy reduces fertilizers that are required to replenish amount by 44%, decreasing to 26.37% in the second rotation. The generated knowledge contributes to this silvicultural practice as it becomes ecologically and economically viable.

“…Aniba rosaeodora Ducke é uma espécie com destaque internacional no mercado de produtos florestais, principalmente pelo óleo essencial, rico em linalol, presente em troncos, galhos e folhas, amplamente utilizado pela indústria da perfumaria e cosméticos (Krainovic et al, 2017). Durante a década de 1960, a exploração seletiva desta espécie causou sua redução populacional em áreas naturais, provocando sua inclusão na lista de espécies ameaçadas de extinção do Instituto Brasileiro do Meio Ambiente (IBAMA, 1992), assim como no apêndice II da Convenção sobre Comércio Internacional das Espécies da Flora e Fauna Selvagens em Perigo de Extinção (CITES, 2010).…”

“…Aniba rosaeodora Ducke é uma espécie florestal da família Lauraceae, considerada de alto valor econômico pela presença de óleo essencial rico em linalol, utilizado como fixador pela indústria da perfumaria (KRAINOVIC et al, 2017). No Brasil, essa espécie sofreu uma intensa exploração seletiva nas décadas de 1980 e 1990 sem a reposição exigida pelo antigo Código Florestal n° 4.771, de 15 de setembro de 1965(Lei Florestal n° 12.651/2012.…”
