Abstract

This study investigates the effects of a high sodium chloride concentration (150 mM) on growth and physiological responses of Lolium perenne L. under controlled vegetation conditions. Given the increasing soil salinity in urbanized areas due to anthropogenic impact, we evaluated the potential of this species for use in green infrastructure in salt-affected environments. It was found that salinisation significantly inhibited shoot and root biomass accumulation. However, leaf chlorophyll content in experimental plants was maintained at the control level and the number of stomata on the lower leaf epidermis increased, thereby ensuring a sufficient level of photosynthesis. Additionally, a reduction in stomatal aperture diameter and a decrease in transpiration rate, along with an increased ratio of root fresh biomass to shoot fresh biomass, contributed to the maintenance of leaf tissue water content. Importantly, the ornamental quality of the aboveground part of the plants was not affected by salinisation. It is concluded that L. perenne is a highly salt-tolerant species and a promising candidate for landscaping in urban areas with elevated soil salinity, including northern regions where de-icing salt use is prevalent
