Abstract

Investigate the effects of salt stress on some physiological and morphological traits in four varieties and four SALINITY levels, including SC302, SC700, BC662, SC704 and Zero (control), 50, 100 and 150 mM NaCl in three replicates for the factorial experiment in randomized complete block design was carried out. During the experiment, several traits including plant height, Stem diameter, chlorophyll a, chlorophyll b, PROLINE and antioxidant enzymes were measured. Between the different SALINITY in the chlorophyll a was seen significant difference. In The chlorophyll b, among different salinities, genotypes and interactions between them no significant difference was found. Between different levels of SALINITY, a significant difference was seen in CATALASE. Between genotypes of the enzyme ascorbate peroxidase significant difference was seen. Highest PROLINE was determined in 100 mM NaCl, in SC302 with 537 micro mol. The most plant height was obtained at zero SALINITY in S.C704 and B.C662. There was no significant difference between them. Maximum chlorophyll a in normal conditions was found in S.C704 with 1.27 mg of chlorophyll per gram fresh weight of leaves. The highest SUPEROXIDE DISMUTASE, were obtained in 50 mM NaCl in SC700. With increasing SALINITY, the amount of CATALASE increased and at 100 mM salt stress reached a maximum. Maximum CATALASE was measured in 100 mM salt in BC662, which with SC302 and SC700 was not significantly different. Of the enzyme ascorbate peroxidase, the enzyme in the greatest amount of salt concentration in 50 mmol in Sc302 with 3.73 was obtained.
