Resumo: Understanding how solar irradiance influences the physiological quality of adult trees of the Paubrasilia echinata morphotypes may help define the reforestation strategies for this species. From the trunk of this tree, the raw material is obtained for the confection of stringed musical instruments. In this study, the flow of carbon and allocation of non-structural carbon-NSC (soluble sugars and starch) and structural carbon (cellulose, hemicelluloses, and lignin) in adult individuals of three Paubrasilia echinata morphotypes cultivated in the shade and full sun were analyzed. The full sun stimulated the stem growth, the CO2 assimilation, and the NSC and lignin accumulation in the leaves and stem of the three morphotypes. However, the medium and large morphotypes showed higher values of these variables. Cellulose did not vary between treatments. Full sun promoted a more significant deposition of stem hemicelluloses in the medium and large morphotypes. Knowing that lignin and hemicelluloses provide higher wood quality, medium and large morphotypes cultivated in the full sun seem to have better commercial use characteristics. However, the large morphotype is the most suitable among these two due to the greater stem lignification.

Do tronco dessa arbórea se obtém matéria-prima para confecção de instrumentos de corda musical. Neste estudo, analisaram-se o fluxo e a alocação do carbono não estrutural-CNE (açúcares solúveis e amido) e estrutural (celulose, hemiceluloses e lignina) em indivíduos adultos de três morfotipos de Paubrasilia echinata cultivadas na sombra e pleno sol. O pleno sol estimulou o crescimento do caule, a assimilação do CO2, assim como o acúmulo de CNE e lignina em folhas e caule dos três morfotipos. Porém, os morfotipos médio e grande apresentaram maiores valores dessas variáveis. A celulose não variou entre os tratamentos. O pleno sol promoveu maior deposição de hemiceluloses no caule dos morfotipos médio e grande. Sabendo que a lignina e as hemiceluloses proporcionam melhor qualidade da madeira, os morfotipos médio e grande cultivados em pleno sol parecem reunir melhores características para o uso comercial. Mas, dentre esses dois, o morfotipo grande é o mais indicado devido à maior lignificação caulinar.Universidade Federal de Santa Maria2021-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4429110.5902/1980509844291Ciência Florestal; Vol. 31 No. 3 (2021); 1472-1493Ciência Florestal; v. 31 n. 3 (2021); 1472-14931980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/44291/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/44291/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessMartins, Carlos Augusto PagottoGama, Vinicius NovoVolponi, Fabiano CapriniMacieira, Bernardo Pretti BecaciciCuzzuol, Geraldo Rogério Faustini2021-09-06T21:13:38Zoai:ojs.pkp.sfu.ca:article/44291Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-09-06T21:13:38Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
