The chlorophyll stability index (CSI; %), Per cent drop in pH of leaf extract and relative water content and greenhouse experiments were used for drought tolerance in seedling rootstocks of mahalep with high germination. Types with high CSI value are determined to be drought susceptible and, but high pH drop of leaf extract determined as tolerant to drought. Similar results and open correlation were found between laboratory experiment and greenhouse experiment. The chlorophyll stability index (CSI; %), pH drop of leaf extract and relative water content can use as preselection criteria. T-78 and T-89 were found as tolerant to drought according to another types. In the pot seedlings with water stressed, leaf K, Mg, Mn and Na content increased but, leaf N, Ca, Zn and Cl contents decreased
