Abstract
The objective was to evaluate the effect of cutting the central leader, in a similar way to that performed by Oncideres saga (Dalman), on the diameter and height growth of Acacia mangium Willd. trees. An experiment was carried out in May 2007 in Coimbra, Minas Gerais, Brazil, with a randomized complete block design, split by the time according to the age of the trees (40 to 46 months). A total of 54 trees were monthly evaluated in three blocks, where three treatments were applied, with six trees in each experimental plot. The applied treatments consisted of "uninjured" (T1 = control), "complete defoliation of the central leader" (T2) and "cutting the central leader" (T3). The diameter at breast height (DBH) and the total height (H) of each tree in the experiment were evaluated. The results were submitted to analysis of variance, test of significance, regression analysis and identity test models. The diameter and height had an increasing linear growth rate.
