Transpiration as Affected by Soil Moisture in Eucalyptus tereticornis Seedlings

An experlmenl was designed to study the transpiration rale of Eucalyptus tereticornis maintained in different soil moisture levels. It was found that transpiration in this species is a function of atmospheric aridity under conlition of abundant soil moisture whereas under condition of restricted soil moisture water conserving mechanisms are in operation. Thus, the dry matter production is not seriously affetted even under conditions of low soil moisture levels.
