Climate change is not only manifested by high temperatures, but means perverse, cascading effects that must be viewed in interaction. Climate change solutions can not only be cost-effective, but also improve the level and quality of life of the population while protecting the environment. In order to improve the situation, at the moment, the following actions are necessary: reducing emissions, adapting to the effects of climate change and financing the necessary adaptation measures. Photosynthesis, respiration, transpiration, stomatal conductance, assimilation, etc. can be used in the plant breeding process, with the aim of identifying plant genotypes with an increased potential for capturing CO₂ from the atmosphere, thus contributing to maintaining the global average temperature within the limits, which would not lead to the intensification of the greenhouse effect and the change of factors climatic. In order to carry out the study, grapevine genotypes of intraspecific origin from the V. vinifera L. and genotypes of interspecific origin (V. vinifera L. x M. rotundifolia Michx.) were used. The measurements were made in the period up to flowering, the formation (growth) of berries and in the period of mature berries (formed). Phytomonitoring was carried out with the help of the PTM-48A monitor, which is an automatic CO2 exchange monitoring system. Studies have shown that the interspecific grapevine genotypes are characterized by much better adaptive features than intraspecific genotypes in relation to climate change. The respective methodology can also be applied in the improvement process of different plant crops.
