Abstract

 

In this study, effect of applied NaCl on growth and stomatal resistance, proline and total chlorophyll concentrations of maize plant (Zea mays L. cv: RX 947) was investigated. The experiment was arranged in a completely randomized design with four replications under the greenhouse condition. The experimental soil was salinized with NaCl at the rates of 0 and 100 mM NaCl. Growth of the maize plants was inhibited by salinity. Applied NaCl significantly decreased dry mass of maize plants.   Stomatal resistance and proline concentrations were increased by high salinity, while total chlorophyll concentration was decreased. NaCl caused to increase Na and Cl concentrations of plant.
