“…The average of the untreated wood was in the range of the results presented in other Brazilian studies of the same species (Maron and Neves 2004, Mocelin et al 2002, Santana 2009, Silvério 2008, expressing the different factors that can influence the chemical composition of a wood sample, such as age and site, for example. According to Bartlett's test (test statistic= 1,446; p-value= 0,079); there was no significant difference of the variances of the treatments, and the ANOVA results (F-ratio= 65,33; p-value= 0,000) showed that there was a significant statistical difference between the averages of the treatments.…”
