ABSTRACT -     Pear is among the fruits of major commercial interest in the world and one of the most imported in Brazil. Brazilian production is very small and the fruit quality is low, due to production problems. The success of culture in the country, among other factors, may be linked to the choice of cultivars, pollinating and rootstocks better adapted to local conditions, and thus depend on the particulars of an agricultural zoning. The aim of this study was to identify, in southern Brazil, homogeneous climatic zones with potential for growing of European and Asian pears, through climate risk studies. The regions were defined by the seasonal availability of chilling hours (&lt;7.2 °C) accumulated during the period from May to September and the monthly risk of drought. The analysis allowed the recognition of four homogeneous areas for the production of pears in southern Brazil.

RESUMO -     A pera está entre as frutas de maior interesse comercial no mundo e é a fruta mais importada pelo Brasil. A produção brasileira é muito pequena, e a qualidade da fruta não tem padrão comercial adequado, em função da falta de adaptação das peras de qualidade às condições edafoclimáticas brasileiras. O sucesso da cultura no País, entre outros fatores, pode estar associado à escolha das cultivares comerciais, polinizadoras e porta-enxertos mais bem adaptados às condições edafoclimáticas locais, dependendo, portanto, das indicações de um zoneamento agrícola. Assim, o objetivo deste estudo foi identificar, na região Sul do Brasil, zonas climáticas homogêneas com potencial para plantios comerciais de pereiras europeias e asiáticas, por meio de estudos de riscos climáticos. As regiões foram delimitadas pela disponibilidade estacional de horas de frio (&lt;7,2 oC) acumuladas no período entre maio e setembro, e pelo risco mensal de ocorrência de déficit hídrico. A análise permitiu o reconhecimento de quatro zonas homogêneas para produção comercial de peras na região Sul.
