E. Bastías; N. Fernández‐García; M. Carvajal Plant Biology 2004. doi:10.1055/s-2004-820889

Other claims from this paper (5)

Intervention effect Under saline conditions, growth and chlorophyll concentration of maize did not change noticeably.
Intervention effect Salinity decreased leaf water potential and osmotic potential in maize.
Intervention effect Boron had no effect on maize in these treatments.
Mechanism The weak response of root hydraulic conductance to Hg in salt-stressed roots suggests water channels were greatly reduced or non-functional.
Association Reduced aquaporin functionality in NaCl-treated maize could be related to reduced B concentrations in roots and leaves.
