Abstract

The role of the definition of the effective “growing season” on the direction and magnitude of four major cereal (hard and soft wheat, maize and barley) responses to recent climate trends is investigated, on periphery scale, throughout Greece, using two effective “growing seasons” for each crop: the full growing season (GS) and the grain filling (GF) period. Historical interpolated data of maximum (Tx) and minimum temperature (Tn), diurnal temperature range (Tr), precipitation (Prec) and solar radiation, over the period 1978–2005, were provided by the MARS-STAT Data Base. The direction of yield and, to a lesser extent, the magnitude of negative yield response to trends of Tx and Tr was not sensitive to the choice of the effective “growing season”. On the other hand, the responses of barley, hard and soft wheat to the warming trends of Tn and decreasing trends of Prec in central Macedonia and Thrace were positive in the case of GS and negative in the case of GF period. The difference of crop responses to the definition of the “effective” growing season, however, was significantly larger to Tn than to Prec trends.
