Variability of the Hydrangea paniculata (Hydrangeaceae) leaf epidermis structure in the culture conditions

The variability of the leaf epidermis structure of Hydrangea paniculata in the culture conditions on the south of the Russian Far East is analyzed. The variability level and the amplitude of the quantitative and morphometric characteristics, pairwise correlations showed that such features do not have taxonomic significance. High polymorphism of quantitative and morphometric characteristics of the leaf epidermis as well as the dependence of the cell and stoma size on their number and leafsize, reflect the adaptive potential and wide ecological plasticity of Hydrangea paniculata.
