Factors affecting CO2 assimilation, leaf injury and growth in salt-stressed duram wheat

James, Richard A; Rivelli, Anna Rita; Munns, Rana Ellen; von Caemmerer, Susanne

Description

To examine the factors that affect tolerance to high internal salt concentrations, two tetraploid wheat genotypes that differ in the degree of salt-induced leaf injury (Wollaroi and Line 455) were grown in 150 mM NaCl for 4 weeks. Shoot biomass of both genotypes was substantially reduced by salinity, but genotypic differences appeared only after 3 weeks, when durum cultivar Wollaroi showed greater leaf injury and a greater reduction in biomass than Line 455. Ion accumulation, water relations,...[Show more]
