Abstract


The aim of this work was to study the phenology of ten species that occur in the “Campos” ecosystem in Paraná state. They are: Borreria suaveolens G. Mey. ; Hilariana Crotalaria Benth. ; Cuphea calophylla Cham. & Schltdl.; Desmodium adscendens (Sw) DC.; Desmodium incanum  DC.; Hypericum connatum Lam. ; Peltodon rugosus Tolmachev; Salvia lachnostachys Benth. ; Been macrodon DC.; Tibouchina gracilis (Bonpl.) Cogn. The monitoring, by qualitative character, realized each fifteen days, had beginning in the month of January of 2007. It had been evaluated reproductive and vegetative characteristics. The meteorological variables that had been related with the phenology were: air temperature, relative humidity, precipitation and photoperiod. The results show that 80% of the species present ending of the period of budding between April and May. Cuphea calophylla was the only species that presented budding during all the observed time. The bighest dispersal of seeds occurred in May and June. Temperature, photoperiod and precipitation had been the variables that had shown better relationship with phenophases of the plants, especially the temperature.
