Leaf shape, stomata density and photosynthetic rate of the common oak leaves

Leaf shape and size, stomata dimensions and density, chlorophyll content and photosynthetic rate of the common oak leaves were investigated in shoots of various growth phases (polycyclic growth).Mean and maximal daily net photosynthetic rates, shoot length, leaf area, stomatal density and chlorophyll contents were significantly higher in shoots of the second growth phase. Intraspecific differences in leaf shape were found within each shoot growth phase.
