Abstract
It has earlier been suggested that the water potential at the roots of rapidly transpiring plants mil be much lower (negatively) than that measured in the soil mass (Jarvis and Jarvis 1963b and c). The difference depends on the rate of transpiration, the conductivity of the soil to water, and the concentration of the effective roots. To study plant response in relation to a known water potential at the root surface, culture solutions containing osmotic substrates have been used. In an earlier paper, response of transpiration in short term experiments was examined (Jarvis and Jarvis 1963b).
