Resumo: The height of the sampling point in acacia trees, where the medium tannin concentration is located, was studied for black acacia, Acacia mearnsii De Willd. The equation hi/h=1.22747 -0.046494.CTA was obtained relating the sample height over the total height to the tannin concentration. Substituing the medium value of CTA, 15.52165%, the value 0.401983 is obtained for hi/h. We concluded that the medium concentration of tannin can be determined at a single height, 40% of the total of the tree stem, independent of the age of the tree.

A altura de amostragem, nas árvores de acácia onde obtém-se a concentração média de tanino, foi estudado em população de acácia-negra, Acacia mearnsii de Willd. Considerando-se a concentração de tanino (CTA) em função da relação altura de amostragem (hi) sobre a altura total (h), obteve-se a seguinte equação: hi/h = 1,122747 - 0,046494 · CTA. Substituindo-se CTA na equação, pelo valor médio da concentração de tanino encontrado de 15,52165%, chegou-se ao valor hi/h = 0,401083. Isto permitiu concluir que a concentração média de tanino pode ser determinada num único ponto de amostragem, localizado a 40% da altura total das árvores, independente da idade.Universidade Federal de Santa Maria1998-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/35510.5902/19805098355Ciência Florestal; Vol. 8 No. 1 (1998); 109-113Ciência Florestal; v. 8 n. 1 (1998); 109-1131980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/355/226Camillo, Shirlei B. de AguiarSchneider, Paulo RenatoSilva, Maria Cladis M. daFrizzo, Sônia Maria Bitencourtinfo:eu-repo/semantics/openAccess2017-06-09T12:12:38Zoai:ojs.pkp.sfu.ca:article/355Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-09T12:12:38Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
