The Effect of Ionizing Radiation on the Stability of Phytocenosis in Conditions of Global Warming

Abstract

This study examines the role of anthropogenic load in shaping plant surface temperature under high and extreme thermal conditions. Gamma irradiation was applied as a universal damaging factor. Field experiments showed that under normal temperatures, the difference between control (non-irradiated) and irradiated plants did not exceed 2–3 °C, while under elevated and extreme temperatures, it increased to 100 °C. Laboratory analyses of transpiration intensity confirmed that radiation is a major factor reducing the transpiration potential of irradiated plants. These findings highlight the relevance of plant resistance under global warming and emphasize the need to minimize anthropogenic impacts on phytocenoses to enhance their resilience to rising temperatures associated with climate change.
