• regression
• form factor
• bark percentage.

this study aimed to test and select models, with and without bark volume, and to determine the form factor and bark percentage of an open ombrophylous forest in northwest mato grosso. 91 trees were cubed by obtaining diameter, bark percentage, stem height and solid stem volume. a total of 10 models were tested. statistical procedures, such as adjusted determination coefficient, residual error and distribution of residuals, were tested. the selected models were validated by the l%26o test. the average form factor was 0.7424 and 0.7297, with and without bark, respectively. the average volume of bark was 0.4292 m3 (7.45% of total volume). the schumacher-hall model showed the best performance for volumes with and without bark.
