The study was performed to determine mineral nutrition preferences and the morphological response against the salt stress of the rootstocks used in Turkey. 41B, 5BB, 140Ru, Salt Creek, and SO4 were used as rootstocks, and NaCl at concentrations of 0 (control), 0.75, and 1.5 g L-1 were applied to the plantlets grown in MS medium. The values of all shoot and root properties examined in this experiment decreased with increasing NaCl concentrations compared to control plants. The highest damage degree was seen on 41B, while there was no damage on Salt Creek plantlets. Shoot and root tolerance ratios of Salt Creek rootstock were found to be the best among the rootstock. These ratios were higher in 0.75 g L-1 than 1.5 g L-1 concentration. Leaf chlorophyll and nutrient content were negatively affected by the increasing NaCl doses. It has been found that all nutrient elements are positively affected by each other's uptake. The highest N, K, Ca, and Mg levels were detected in Salt Creek, while the lowest level was detected in 41B rootstock. Considering all the parameters examined, rootstocks are ranged from the most sensitive to the most resistant to salinity conditions; 41B, SO4, 5BB, 140Ru, and Salt Creek.
