Abstract

This study analyzed the phenological patterns of tree synusia, and their relationships with climate variables, in a forest fragment in the municipality of São Miguel do Oeste, SC. From October 2012 to October 2013, phenological events were evaluated using the number of species in the phenophase and the Fournier intensity index. Individuals of twenty species of trees (in 13 families) were monitored for budding, presence of mature leaves, leaf fall, flowers at anthesis, and presence of immature and mature fruits. The standardized Morisita index was used to test seasonality of the phenophases and the Spearman correlation was used to evaluate the possible relationships of phenophases with temperature and precipitation. Leaf fall was seasonal and had a high negative correlation with temperature. Budding and flowering showed seasonality and high intensity in September. Mature and immature fruits occurred at different times throughout the year. The triggering of the phenophases was correlated with temperature, mainly for the vegetative phenophases.
