The influence of soil moisture on stomatal conductive responsiveness to CO2

Abstract

Plants have the ability to reduce their transpirational water loss under high CO2 conditions by changing their stomatal conductance (gsmax). Changes in stomatal conductance can have severe effects on local hydrology; therefore it is important to understand how plants have adapted to the industrial rise in CO2 and how soil moisture influences the responsiveness of plants to CO2. This paper focuses on the effects of different soil moisture regimes on stomatal conductance changes and how these changes may affect the environment.
