Fenologia de Brosimum gaudichaudii trÉcul. (Moraceae) no cerrado de mato grosso

Abstract

Brosimum gaudichaudii Trécul., a typical species of'cerrado' is very much appreciated due to the sweet taste of its fruit and as a medicinal plant in the treatment of vitiligo. Phenological studies provide information for understanding the dynamics of forest ecosystems and for managing native species. The aim of this study was to evaluate the phenology of species by means of two methods: the intensity of the phenologic event characterized by the scale of Fournier and the presence/absence of the event, both expressed by the activity index and intensity index. We randomly selected 49 individuals and identified the growth stage and followed every 20 days, from 2006 to 2008, describing the activity index and intensity index, as the scale of Fournier. The index of synchrony (Z) was 0.96 for foliage, 0.65 to sprout, 0.69 for flowering and 0.72 for fruiting. The leaf fall occurred in July and the shooting was more intense (80%) in October. Flowering occurs between June and October 2007, with peak intensity in August (52%) and increased activity in September (92%); fruiting occurred between August and December 2007, with 91% of individuals in activity in October but, intensity of 25% for the same period. Brosimum gaudichaudiiTrécul. is a deciduous plant and phenological events are conditioned to seasonal climate variations, precipitation mainly.
