Mudanças climáticas e a fruticultura

Abstract

RESUMO -O objetivo do estudo é descrever evidências estatísticas de mudanças climáticas que podem impactar as atividades agrícolas, em especial a fruticultura. Embora tenham sido utilizados diversos estudos realizados em distintas partes do globo, foi dada especial atenção aos conduzidos sob as condições climáticas do Estado de São Paulo, Brasil. Nas séries de temperaturas mínimas atmosféricas, são encontradas significativas tendências de aquecimento. Contudo, nenhuma elevação consistente pode ser verificada nos valores de temperatura máxima do ar. As análises estatísticas também não têm sido capazes de indicar uma coerência espacial na variabilidade temporal associada à precipitação pluvial. Entretanto, alguns resultados estatísticos, obtidos para o Estado de São Paulo, parecem indicar um recorrente atraso na retomada da estação chuvosa. Termos de indexação: temperatura do ar, precipitação pluvial, tendências. CLIMATE CHANGE AND THE FRUIT CULTUREABSTRACT -The aim of the study is to describe statistical evidences of climate changes that may impact the agricultural activities, mainly the fruit culture. The evidences were obtained from several studies carried out throughout the world. However, it was given special focus to the climate conditions of the State of São Paulo, Brazil. It has been observed significant increasing trends in the minimum air temperature over several regions of the Globe. It has also been observed no consistent trend in the maximum air temperature. Concerning rainfall events, the statistical analyses have shown a lack of spatial coherence in the temporal changes of this meteorological variable. For the State of São Paulo, it was verified some statistical results that may be linked with a recurrent delay in the resumption of the rainy season.

Peach cultivars and new IAC selections for mild winter

“…These states show regions suitable for stone fruits production, however, present a mild winter and not always provide the chill requirement of cultivars developed in traditional areas in United States, Europe or Asia. In addition, climate changes may lead to warmer conditions in several regions (BLAIN, 2011;IPCC, 2018), affecting the performance of elite cultivars currently used (GRADZIEL, 2022;MILECH et al, 2022). These aspects highlight the need for local development of peach and nectarines cultivars (SOBIERAJSKI et al, 2016).…”
