In this study, the effects of salt stress on pigment and
total soluble protein contents were investigated in
different varieties of tomato (Lycopersicon esculentum
Mill.). The seedlings of L. esculentum viz. Hazera,
Dalli Tokat and Argy were treated with NaCl at 25, 50, 100,
125, 150 and 200 mM concentrations for 96 with 24 h
interval. Pigment and total soluble protein contents of all
tomato cultivars were significantly decreased by salt stress
depending on time intervals and salt concentrations.
Decreasing of pigment and total soluble protein contents
were more evident in Hazera under short time salt exposure.
Pigment content of Argy plants were less affected by salt
concentration and exposure time. The results of this study
suggest that the Argy cultivars are relatively better
protected under salt stress conditions than Dalli tokat and
Hazera cultivars.
