Features of photosynthesis of some woody and shrubby plants of the Southern Coast of Crimea
Abstract
The research was conducted in August 2025 in the natural plantings and park communities of the Southern Federal District. The specifics of photosynthesis were studied using a portable «Floratest» chronofluorimeter. To assess the functional state of the photosynthetic apparatus in the studied plant species, the parameters of induced photosynthetic fluorescence (IPF) were measured. Studies of the specifics of photosynthesis have revealed that under conditions of exposure to drought and elevated temperatures, significant species differences occur in the level of response of woody and shrubby plants of the SCC to the effects of negative weather events. Decreased values of variable fluorescence were found in Q. pubescens. At the same time, the values of Fv/Fst and Fv/Fm, which determine the quantum yield of photosynthesis and the potential quantum efficiency of FS 2 in Q. pubescens, were lower in comparison with Q. ilex and F. ornus. For Q. pubescens, a low indicator of the vital condition is noted. In general, according to the features of photosynthesis, the autochthonous species Q. pubescens, during the dry period of summer season, showed a decrease in the level of physiological processes of maintaining vital functions in comparison with introduced species of woody plants. Of the shrubby plants, B. аquifolium was characterized by the highest resistance to drought and elevated temperatures. In these conditions, A. japonica showed a significant decrease in indicators characterizing the efficiency of photosynthesis and the vital state of plants.
