Abstract

The effect of salt stress on some physiological traits of wheat (Triticum aestivum L.) was studied under growth chamber condition in a factorial experiment based on completely randomized design with three replications. Salinity treatments carried out in three levels (0.0, 50.0 and 100.0 mM) NaCl. Three wheat landraces (white heteyeh, black heteyeh and Norsi.) were studied. Relative leaf water content (RWC), chlorophyll content (SPDA), plant fresh weight and plant dry weight were measured at seedling stage. Salinity stress decreased relative water content (RWC), whereas chlorophyll content, fresh weight and dry weight were not affected. Based on the obtained results “Norsi” may be considered as the most tolerant landrace, since it showed the lowest reduction percent in LRWC under 50 and 100 mM NaCl.
