Abstract [eng] The world rapidly growing population, expanding economics and anthropogenic activities contribute to the pollution of heavy metals, which are extremely persistent elements in the environment and represent a threat to biota and ecosystem services. Moreover, because anthropogenic CO2 and other greenhouse gases have reached an unprecedented level, at the moment, key ecosystems and ecological processes are simultaneously experiencing pollution-related and climate-related stresses. Cadmium (Cd) is one of the fourth most toxic trace elements in soils without a physiological function in higher plants that causes various symptoms of phytotoxicity. Rape is considered as an efficient phytoremediator of Cd under current climate conditions. Therefore, the growth chamber experiment with pot-grown oilseed rapes was conducted in this study under a controlled environment to evaluate the potential of rape, as a multipurpose fast-growing annual crop with high biomass production, to remediate Cdcontaminated soil under warmer climate conditions (elevated atmospheric CO2 and temperature). As photosynthesis plays an essential role in plant growth and biomass production, the Cd-phytoextraction performance in rapes under warmer climate conditions was evaluated using leaf gas exchange and chlorophyll fluorescence parameters, in this study.
