AbstractAn experiment was conducted to evaluate the effects of salt stress on safflower genotypesunder greenhouse condition using hydroponics nutrient solutions The experiment wasarranged as factorial based on a completely randomized design with three replications Five safflower genotypes of Arak2811 Nebraska10 SOD25 CA116 and CA128 and foursalinity treatments of 0 S0 0 3 S1 0 5 S2 and 0 7 S3 percent of NaCl were used asexperimental factors The effects of salinity were studied at germination stage in laboratoryand also at one and two months after imposing plants to salinity in greenhouse Thegermination rate germination percentage and the shoot and root length of germinated seedswere significantly reduced under salinity treatments There were no interactions betweenthe levels of salinity and genotypes for the rate and percentage of germination However the percentage of decrease in the growth of the shoot and root of germinated seeds washighest for Arak2811 compared to the other tested genotypes Salinity had considerableeffects on the growth parameters Plant height number of leaves per plant shoot and rootdry matter and also the concentration of K Ca and Mg in plant tissues were decreased asthe level of salt was increased in the solution The concentration of Na and the ratio ofNa K in the leaves stems and roots were higher in the plants affected by salt stress Among tested genotypes CA128 showed to be more salt tolerance in terms of dry matteraccumulation There were significant correlations between the concentration of K Ca andMg in plant tissues with plant growth parameters The results of this experiment showedthat salinity may have significant effects on the growth of safflower plants and theresponses of safflower genotypes to salinity can be different
