Abstract: The goal of the presented study was to clarify stomatal closure and water content changes in the leaves of Acer campestre L. in relation to drying of substratum.
We supposed that field maple would preserve water in the leaves by stomatal closure after substratum drought detection. Relative water content in the leaves, water content of the soil and
stomatal conductance was measured. Duration of the experiment was forteen days. Three years old plants originating from dry sites of south Slovakia were used in the experiment.
According to the obtained results, A. campestre L. was able to preserve standard water content in the leaves seven days after water scarcity introduction. Water content in the
leaves rapidly decreased after seven days in drought conditions. Stomatal closure was observed after three days in drought conditions. Decrease in stomatal conductance on next days was rapid.
Keywords: Acer campestre L., stomatal conductance, relative water content, drought
