Movement of Water Out of the Plant-Soil System,our in the foliage or at the surface of the soil. By far the largest part of this energy enters as shortwave radiation from the sun. A comparatively small component comes in as advective energy, that is energy derived from a change in the temperature of the air as it passes over the evaporating or t

Horticultural Implications,t through its transpiring surfaces into the atmosphere; the result of this hindrance is increase in suction pressure deficit within the plant tissues and this is intensified by high evaporating conditions — strong sunlight, high temperature, low humidity and fast air movement. These conditions are t

Entry of Water Into the Plant,r end, and so the water flows. Its movement up the plant depends on the water having sufficient cohesion to remain in intact columns in spite of the tension exerted by removal (evaporation) of water from their upper ends. This concept is therefore known as the cohesion-tension theory.

Water Within the Plant, most successful of root pressure demonstrations. The rate of exudation from a detopped plant is usually only of the order of 5 per cent of the previous transpiration rate of the intact plant. Thus osmotic uptake of water into the roots cannot explain the flow of water to the tops of trees.
