Effects of Salinity Stress on Stomatal Variations of Hedysarum coronarium L. and Hedysarum criniferum Boiss

Effect of salt stress on the stomata variations was studied in Hedysarum coronarium L. and Hedysarum criniferum Boiss., using light microscope instrument. The experimental design was a two factorial (species treatments and salt concentrations including 0, 100, 200, 250 mM NaCl) which arranged in a completely randomized design with four replicates and 50 seeds per replicate. Seed were grown in plastic pots with sterile sand. All pots were irrigated by distilled water until germination stage. Then the pots were irrigated uniformly every other day with modified Hoagland’s nutrient solution during 40 days and finally stomata traits were measured. The data were analyzed using SPSS software. The difference between the means was compared using Duncan test (P
