A Climate profile indicator based comparative analysis of climate change scenarios with regard to maize (Zea mays L.) cultures

摘要

Using ecological data compiled from scientific literature on pest, pathogen and weed species characteristic in maize cultures in Hungary, we defined monthly climate profile indicators and applied them to complete a comparative analysis of the historical and modelled climate change scenario meteorological data of the city of Debrecen. Our results call attention to a drastic decline of the competitive ability of maize as compared to several C4and especially C3 plants. According to the stricter scenarios, the frequenc y of potential pest and pathogen damage emergency situations will grow significantly by the end of the century
