Resumo: In this work, it is studied the growth of Nectandra megapotamica (Spreng.) Mez species through a sampler compounded by eleven dominant trees selected from a rainforest in Nova Prata, Rio Grande do Sul. The mathematical model which better represents the growth trend in percentage volume was described as iv%=(b0+b1.ln d)2, fitting individually per tree, being possible to describe the variations of slope (b1) and intercept (b0) coefficients between trees with the relation height – diameter (h/d), diameter increment measured on the last 5 cm on bore increment (id5) sampled on diameter breast height (d), exposition (EXPOS), corrected Basal Area Large (BALcor) and crown length exposed to sunlight (Lc), considering the following expressions: b1= 0,41739 + 4,16179.id5 - 6,29332.h/d + 0,37823.EXPOS - 0,11519Ir + 5,80419.BALcor – 0,06858.Lc, with determination coefficient equal to 0,9979 and standard error in percentage of the mean of –1,73%, and b0= 2,62466 –13,37024.id5 + 22,08329.h/d – 1,33161.EXPOS + 0,34689.Ir –23,88899.BALcor + 0,25692.L, with determination coefficient fitting on 0,9907 and standard error in percentage of the mean of 2,71%.

O crescimento de árvores dominantes de Nectandra megapotamica (Spreng.) Mez, amostradas em Floresta Ombrófila Mista, no município de Nova Prata,  RS foi reconstruído com base em dados obtidos com a técnica da dendrocronologia. O crescimento volumétrico expresso pelo incremento percentual foi modelado para cada árvore por iv% = (b+ b1.ln d)2, e a seguir comparadas por análise de covariância, permitindo classifica-las em 3 grupos distintos quanto a inclinação do modelo (b1) e intercepto (b) das linhas de regressão. Os coeficientes de inclinação e intercepto foram modelados como função da variável altura - diâmetro (h/d), incremento diamétrico medido sobre rolo de incremento nos últimos 5cm (id5) amostrado ao nível do diâmetro a altura  do peito(d), exposição do terreno (EXPOS), índice de competição BAL corrigido (BALcor), e comprimento da copa exposta a luz (Lc), pelas equações b1 = 0,41739+4,16179.id5-6,29332.h/d +0,37823.EXPOS-0,11519Ir+5,80419.BALcor-0,06858.Lc, com coeficiente de determinação ajustado igual a 0,9979 e erro padrão em percentagem da média de - 1,73%, e b= 2,62466-13,37024.id5+22,08329.h/d- 1,33161.EXPOS+0,34689.Ir-23,88899.BALcor+0,25692.Lc, com coeficiente de determinação ajustado de 0,9907 e erro-padrão em percentagem da média igual a 2,71%.Universidade Federal de Santa Maria2009-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/88610.5902/19805098886Ciência Florestal; Vol. 19 No. 3 (2009); 305-314Ciência Florestal; v. 19 n. 3 (2009); 305-3141980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/886/614Souza, Luis Henrique da SilvaFinger, César Augusto GuimarãesSchneider, Paulo Renatoinfo:eu-repo/semantics/openAccess2017-05-08T14:01:00Zoai:ojs.pkp.sfu.ca:article/886Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-08T14:01Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
