In the two cases the problem of water requirement and its consumption is different. In fact, little similarity can be found in regard to plant water balance between forest and horti- or agricultural

All this takes place despite the fact that the available soil moisture in the root zone was depleted by the end of June or July. Furthermore, the minimum soil moisture level after this period is greater than that in an open, unforested area identical t

This shortage has given us the idea of exploiting water from dew and mist of irrigation of forest plants, and of concentrating the little rainwater available into the immediate area of the roots.

According to them, wind decreases the concentration of water vapor at the leaf surfaces, and thus increases the rates of transpiration. . (1956), found that the leaves of . often show a

The physical environment is the workshop which shapes the morpho-anatomo-genesis of the tree and its form of life. A plant growing in its natural habitat without the interference of man is completely adapted to the surrounding environment after an
