This pot experiment was conducted to evaluate the response of potato plants to different levels of salinity in terms of plant dry mass (PDM), root dry mass (RDM), plant height, number of stems and some mineral elements analysis from aerial parts of potato plants. Two potato cultivars namely, Madrid and Alver stone russet were exposed to three levels of salinity (0, 50 and 100 mM). Pots test plots were arranged in a randomized complete block design with three replications. Salt stress left significant effects on all characters, i.e., biomass and height of potato plants were decreased, but Na content was increased significantly with salt stress. As well, our results revealed positive correlation among K content and RDM in the treatment 50 mM and P content and PDM in the treatment 100 mM of salinity. On the other hand, the results revealed that increasing concentrations of salinity have negative effects on biomass and plant growth in all tested potato cultivars.
