Floristics and Reproductive Phenology of Trees and Bushes in Central West Brazil
Environmental conditions such as temperature, soil, photoperiodic factors and precipitation can determine the physical environment favoring the occurrence of given species and interfere with the reproductive period of plants. This work involved monthly excursions to a slope in the Serra de Maracaju between December 2009 and November 2010. Samples were collected in eight 25 x 50 m plots, transverse to the slope, totaling 1 ha sampled. Floristic richness included 79 species distributed into 58 genera and 31 families. Floristic Similarity Analysis and Principal Component Analysis showed the occurrence of two plant formations on the slope: seasonal deciduous forest andcerradão on the eutrophic soil of the slope. Flowering and fruiting occured in the rainy season; correlation with rainfall, mean temperature and photoperiod were negative for flowering and positive for fructification. Trees and bushes presented uniform flowering and a moderately seasonal fructification, which is unexpected in seasonal environments. We discuss the implications of the patterns found and make comparisons with others studies.
