Abstract

The aim of this work is to study the phenology of twelve species that occur in “Campos” ecosystem in Paraná state. This research was carried out at the Universidade Federal do Paraná, Campus III, in Curitiba city. The selected species for phenologic evaluation were: Aspilia montevidensis (Sprengel) Kuntze, Cacalia cognata (Less.) Kuntze, Campovassouria bupleurifolia (DC.) R. M. King & H. Rob., Campuloclinium macrocephalum (Less.) DC., Chromolaena ascendens (Sch. Bip. ex. Baker) R. M. King & H. Rob., Lessingianthus glabratus (Less.) H. Rob. (Asteraceae), Eryngium sanguisorba Cham. & Schtdl. (Apiaceae), Moritzia dusenii Johnston (Boraginaceae), Petunia linoidesSendtn. (Solanaceae), Senna neglecta (Vogel) H. S. Irwin & Barneby (Fabaceae), Tibouchina gracilis (Bonpl.) Cogn. (Melastomataceae) and Verbena rigida Spreng (Verbenaceae). The applied methodology was the qualitative evaluation of the phenological data (florescence and fruiting) observed every fifteen days during the year 2004. The climatic variables as temperature, relative air humidity, precipitation and photoperiod were obtained daily to verify its relation with the phenophasis. The results showed that from all studied species, six of them presented reproductive phenology between January and August, while the others just had an interruption in the reproductive period during winter, except Aspilia montevidensis, which presented florescence and fruiting throughout the year.
