The unfavourable effects of climate change were studied in terms of changes in the stress tolerance of cereals. The yield and physiological parameters of two winter wheat genotypes (Mv Mambó, Mv Regiment) were analysed in the phytotron after water was completely withheld for 7 or 14 days in three phenophases. The plants were raised in climate chambers, one adjusted to ambient CO2 concentration and the other to a higher level (750 μmol mol−1). The aim of the present work was to determine the correlations between the duration of water withholding and the phenological, physiological and yield parameters of winter wheat. It was hoped to identify how elevated CO2 levels affected the stress sensitivity of plants and whether they contributed to counteracting the damaging effects of drought. In both varieties, the grain mass decreased to the greatest extent when water was withheld at first node appearance (5.9–71.3%). A longer period of drought at first node appearance and grain filling only reduced the grain number and mass in the case of enhanced CO2. The yield and physiological parameters of Mv Regiment, however, deteriorated substantially as a result of water deficiency, though this variety was better able to utilise surplus CO2, giving outstanding results at elevated CO2 level.
