2.4. Morphological and physiological analyses
2.4.1. Anatomical features of leaf
The anatomical analysis of the mesophyll cells in the leaves of
the young plants was performed using the method of Clark (1981).
The anatomical structure of the mesophyll cells of the leaves was
examined under a light microscope (DP71, OLYMPUS Inc., Japan).
We analyzed 10 images per leaf, one leaf per plant and 5 plants per
treatment. The experiment was repeated 6 times. Leaf thickness,
length of palisade cells and parenchyma cells were calculated from
30 epidermis measurements.
