Differences in photosynthetic apparatus of leaves from different sides of the chestnut canopy
In crowns of chestnut trees the absorption of radiant energy is not homogeneous; leaves from the south (S) side are the most irradiated, but leaves from the east (E) and west (W) sides receive aroundExpand
