At the present work it was studied growing of Nectandra megapotamica (Spreng.) Mez species, through a sampler compounded by 11 dominant trees selected from rainforest in Nova Prata borrough, state of Rio Grande do Sul. The growth of the sampler trees can be give up successfully through steam analysis determ the growth trend in percentual volume along time, for the selected trees. The mathematical model better represents the growth trend in percentual volume was described as iv%=(b0+b1.ln dap)2, fitting individually per tree. Covariance analysis earn possible to cluster three groups, contends trees with decreasing trend were similar in relationship to trend and curves level, being possible to describe this variations with mathematical models using independent factors, as: morphomety, competition and environmental from the trees in case, by expressions : b1 = 0,41738583 + 4,16179208.id5 - 6,29332107.h/d + 0,37822636.EXPOS - 0,11519372.Ir + 5,80418708.BALcor 0,06858050.Lc, with determination coefficient equal to 0,9979 and variation coefficient of 1,73%, as well as the differences between curves levels by equation b0 = 2,62465943 13,37023979.id5 + 22, 08329412.h/d 1,33160878. EXPOS + 0,34688547.Ir 23,88899208.BALcor + 0,25692291.Lc, with determination coefficient fitting on 0,9907 and variation coefficient of 2,71%.
