Agrobiodiversity prodcutive systems in the minipalities of traditional Antonia and Morretes of state Paraná

Abstract

The present study was to identify, characterize and assess the agrobiodiversity and its role as keeper of the agriculture/forestry practiced in traditional growing areas in the cities of Antonina and Morrettes in Paraná. For this study 20 were productive systems with sizes comprised 1-3 fiscal modules. Evaluations were made by means of direct observations in the field and phytosociological analysis identifying the species and obtaining data for calculation of diversity index in each municipality, for that the indices of Shannon-Weaver and Simpson for the determination of wealth and dominance, this information agrobiodiversity based the determination of the properties, the results show that despite low scores there is a diversity of agriculture in the region, but this diversity is restricted to improve this aspect, the enrichment of present production systems with the largest number of subjects, especially tree species. By analyzing the phytosociological can observe farmers' preferences for certain species including: Musa sp., Psidium guajava L., Euterpe edulis Martius, Manihot sp., Passiflora edulis Sims, Saccharum sp. Farmers in Morretes showed greater interest in arboreal crops, while the producers in Antonina showed a preference for crops.
