Abstract

The objective of this research was to investigate the monthly growth rhythm of young trees of Araucaria angustifolia and Pinus taeda throughout the vegetative year and to establish its correlation with climatic variables. Monthly measurements of diameter and total height were carried out in one stand of A. angustifolia and two of Pinus taeda. Correlation matrices among the current monthly increments and the climatic variables indicated that the development of Pinus taeda is mostly affected by photoperiod and by minimum, average, and maximum temperatures, while A. angustifolia growth is affected mostly by minimum and average temperatures.
