“…The yield reduction under drought stress dropped by approximately one half under elevated CO 2 compared to ambient conditions. The physiological background of this result might be that the high CO 2 concentration modifies the intensity of the photosynthesis [39,41], decreases the stomatal conductance and increases the evaporation [42]. Based on this, it can be concluded that although the influence of elevated CO 2 on the aboveground parts of the plants is well-known, the development of the root system should also offset the increased water loss and nutrient uptake.…”

The intensity and the frequency of extreme drought are increasing worldwide. An elevated atmospheric CO2 concentration could counterbalance the negative impacts of water shortage; however, wheat genotypes show high variability in terms of CO2 reactions. The development of the root system is a key parameter of abiotic stress resistance. In our study, biomass and grain production, as well as the root growth of three winter-wheat varieties were examined under optimum watering and simulated drought stress in a combination with ambient and elevated atmospheric CO2 concentrations. The root growth was monitored by a CI-600 in situ root imager and the photos were analyzed by RootSnap software. As a result of the water shortage, the yield-related parameters decreased, but the most substantial yield reduction was first detected in Mv Karizma. The water shortage influenced the depth of the intensive root development, while under water-limited conditions, the root formation occurred in the deeper soil layers. The most intensive root development was observed until the heading, and the maximum root length was recorded at the beginning of the heading. The period of root development took longer under elevated CO2 concentration. The elevated CO2 concentration induced an accelerated root development in almost every soil layer, but generally, the CO2 fertilization induced in the root length of all genotypes and under each treatment.

“…About the carbohydrate content, studies conducted in controlled and FACE facilities showed that rising [CO 2 ] contributes to increases in starch and soluble sugar contents in wheat grains 29 – 31 . The larger photosynthetic rates of C 3 plants such as wheat under increasing [CO 2 ] may contribute to increased carbohydrate translocation from the source (leaves and stems) to the sink (grains), where the C is mainly stored in the form of starch.…”

The current study focuses on yield and nutritional quality changes of wheat grain over the last 166 years. It is based on wheat grain quality analyses carried out on samples collected between 1850 and 2016. Samples were obtained from the Broadbalk Continuous Wheat Experiment (UK) and from herbaria from 16 different countries around the world. Our study showed that, together with an increase in carbohydrate content, an impoverishment of mineral composition and protein content occurred. The imbalance in carbohydrate/protein content was specially marked after the 1960’s, coinciding with strong increases in ambient [CO2] and temperature and the introduction of progressively shorter straw varieties. The implications of altered crop physiology are discussed.
