Under phytotronic conditions investigations were made on the effect ofimportant environmental factors, such as temperature, water and an increasingconcentration of atmospheric CO2, on the hardening of young cereal plants.In all the varieties derived from the major wheat growing regions of theworld the hardening process was favourably influenced by a doubling ofatmospheric CO2 content, so that a significantly larger number of plantssurvived the frost test than for plants of the same variety raised undernormal conditions. A reduction in freezing temperature and an increase insoil moisture content caused a slight reduction in survival % for varietieswith excellent frost resistance and a great reduction for those with mediumor poor frost resistance. Predictions suggest that in Central Europe, as theresult of global climatic changes, there will be a reduction in the quantityof winter precipitation, a considerable rise in winter temperatures and anincrease in atmospheric CO2 concentration. Judging by the experimentalresults, these changes could improve the overwintering of winter cereals; atthe same time, however, a number of factors (mainly the reduction ofprecipitation) leading to yield losses must be expected during the vegetationperiod.
