Influence of the stump diameter and height on the growth and vigor of eucalyptus sprouts

ABSTRACT Forest stands managed with the coppicing technique tend to display a decreased production in subsequent rotations, demanding high stump sprouting rates, so that planting succeeds. This study aimed assess vigour of eucalyptus sprouts on basis stumps diameter and height. The number height highest sprout were assessed regarding diameter, providing following treatments: smaller than 12 cm diameter; from 15 cm; 15.1 18 larger cm. was also as function cutting stumps, near ground at 5, 10 above ground. did not influence amount sprouts, but exerted after 120 150 days resprouting. had great indicating that, despite reducing volume timber harvested, provided expressive gains stand regeneration. clones by system.
