Abstract
were applied. The number of leaves and length of branches was also registered with the application of an analysis of variance for different sampling times. Cuttings taken from the basal section had less days for the appearance of the callus, with a mean of 7.5. They reached a height of 17.25 cm at 45 d. In growth, the quadratic model showed better adjustment for plant height with rates between 0.15 and 0.11 cm/d. For sprout diameter, the linear model was
superior, with a rate of 0.024 mm/d. There was a predominance of green leaves and regarding the length of branches, differences were found for different seasons. It is concluded that the species did not stop its growth during the first 320 d after planting. Emission, growth of branches, and number of leaves were also important elements for growth.
Key words: height, plant diameter, establishment, auxins
