Abstract
<p>In this work, it is studied the growth of <em>Nectandra megapotamica</em> (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 i<sub>v</sub>%=(b<sub>0</sub>+b<sub>1</sub>.ln d)<sup>2</sup>, fitting individually per tree, being possible to describe the variations of slope (b<sub>1</sub>) and intercept (b<sub>0</sub>) coefficients between trees with the relation height – diameter (h/d), diameter increment measured on the last 5 cm on bore increment (i<sub>d5</sub>) sampled on diameter breast height (d), exposition (EXPOS), corrected Basal Area Large (BALcor) and crown length exposed to sunlight (Lc), considering the following expressions: b<sub>1</sub>= 0,41739 + 4,16179.i<sub>d5 </sub>- 6,29332.h/d + 0,37823.EXPOS - 0,11519I<sub>r</sub> + 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 b<sub>0</sub>= 2,62466 –13,37024.i<sub>d5</sub> + 22,08329.h/d – 1,33161.EXPOS + 0,34689.I<sub>r</sub> –23,88899.BALcor + 0,25692.L, with determination coefficient fitting on 0,9907 and standard error in percentage of the mean of 2,71%.</p>
