Abstract: The pot experiment with the selected plants of Cornus mas L. was carried out in 2013. The aim of the experiment was
to assess the impact of water scarcity in the substrate on the physiological condition of the monitored plants. Following
physiological characteristics: the leaf stomatal conductance and chlorophyll fluorescence were tested. We have seen the
value of Fv/Fm in the range of 0.75–0.85, which represent the optimum values of Fv/Fm. Values of ΦPSII and the values of
Rfd decreased due the impact of water deficit. By measuring leaf stomatal conductance (gs), we reported a decrease in the
values of the variant with lower levels of saturation of the substrate. We can deduce that the photosynthetic activity of the
plants Cornus mas L. was affected by lower levels of saturation of the substrate.
Keywords: Cornus mas L., leaf stomatal conductance, chlorophyll fluorescence
