Elevated Atmospheric CO2 Concentration Influences the Rooting Habits of Winter-Wheat (Triticum aestivum L.) Varieties

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