- Abstract
The aim of this study was to evaluate the life cycle and competition of Ocotea odorifera (Vell.) Rohwer in Araucaria Forest. We selected understory and emerging trees from the Chapecó National Forest, Santa Catarina State. The diameter, crown projection and total heights of each sampled tree were measured. Samples were obtained with increment borer and the growth rings were analyzed to determine the growth in diameter. Competition indexes were calculated and hypsometric models and growth models were adjusted for each height class (< 11 m and ≥ 11 m). The individuals were aged between 47 and 220 years, in diameters from 17 to 90 cm at 1.30 m in height (DBH). It is a long-lived species, with an average increment of 0.42 cm year-1 . The average annual increment differs between classes of height and diameter, being smaller for trees under the canopy. The Glover and Hool index reflected this condition, indicating that trees with a smaller diameter are under greater competition. The analysis of the competition indexes and the growth models allow to establish a prognosis of the growth of O. odorifera, serving as basis to the management planning for use and/or conservation.
