Aluminum prevents stomatal conductance from responding to vapor pressure deficit in Citrus limonia [PDF]

Environmental and Experimental Botany, 2018
Abstract Stomatal aperture generally increases in response to low vapor pressure deficit (VPD) and decreases at high VPD. Aluminum (Al) inhibits root growth, indirectly exposing the roots to low water availability, which may decrease leaf hydration and, consequently, the stomatal conductance (gs).
