Salinity-induced stomatal resistance, proline, chlorophyll and ion concentrations of bean

Abstract

Salinity-induced effects on the growth and stomatal resistance and proline, total chlorophyll, Na, Cl and K concentrations of bean (Phaseolus vulganis L. cv: Strike) were investigated. In the greenhouse experiment, salt was applied to the soil which was taken from Aridisol soil group at the concentrations of 0 and 100 mM as NaCl. NaCl treatment inhibited the growth and significantly decreased the dry mass of bean plants. While stomatal resistance, proline, Na and Cl concentrations of plants were increased by high salinity, total chlorophyll and K concentrations of the bean were decreased. © 2007 Academic Journals.
