ABSTRACT
This work was undertaken to verify the effect of environmental variables such as the relief position, exposition, downward slope, soil and soil preparation on the dominant height growth, as base to establish a future system of growth and production prediction for three clones of Eucalyptus saligna. For the analysis of environmental factors influence on the dominant height growth pattern the covariance analysis was used. The covariance analysis indicated that the soil was the environmental factor responsible for the variation in the growth pattern in dominant height and that the variations in this pattern, occurred among clones and within the clone. There were observed six different growth patterns, indicating that the curves of site index should be built being taken in consideration the clone and the soil group.
Key words:
Eucalyptus; clones; growth curves; dominant height
