ABSTRACT
The purpose of this study was to evaluate the influence of meteorological variables in the growth of forest trees in an area of Ombrophylous Floodplain Forest belonging to REPAR in Araucaria, State of Parana. The sample comprised 20 plots of 10 m × 10 m plots. In order to follow the timing and rate of growth of the main tree species, from July 2009 to July 2010, the selected individuals received dendrometric bands. The meteorological data were obtained from the meteorological station of Curitiba, provided by SIMEPAR. The meteorological data and the growth of each species were compared using Pearson’s correlation. The species showed different behavior according to sociological position and the fact of being native or exotic. The weather variable that most influenced the growth of the species was temperature, with a positive correlation to Hovenia dulcis and Sebastiania commersoniana, for individuals in the canopy; and to Ligustrum lucidum, Myrrhinium loranthoides and Sebastiania commersoniana, for individuals in the understory.
