Abstract

By applying the various scenarios on global warming we examined the crop temperature in maize at Keszthely with the help of Goudriaan’s micro-climate simulation model. Our scenarios contained several ideas with higher warming up beside the domestic downscaling of the IPCC 2007 report (A2 and B2). We found that the temperature in maize at cob level increased by 0.6 °C in Keszthely, compared to the 1961–1990s. The presence of the canopy slightly compensated the rise in plant temperature, even at simulations with rather high warming up. Compensation degree depended on water supply, too. The better water supply brings more intensive development of green surface of plants so provides stronger shadowing effect; this also affected the development of plant temperature.
