In cold regions, potatoes are planted in spring. Challenges regarding potato cultivation in the  areas facing spring  frost, early fall cold and summer heat which has been investigated in this study. This search a factorial experiment in a randomized complete block design was conducted with three replications in 2015 and 2016 in Gandoman regian, Chaharmahal Bakhtiari Province. The first factor was three cultivar: Jelly, Fontaine and Bouren And the second  factor, was combination of different treatments in six levels of calcium and jasmonic acid (at a concentration of 5 mM) incuding: 1- calcium + jasmonic acid before the stage of rhizome production (T1); 2- calcium + jasmonic acid after the stage of rhizome (T2); 3- jasmonic acid before the stage of rhizome production (T3); 4- jasmonic acid in after the stage of rhizome production (T4); 5- calcium from calcium nitrate source (T5); 6- control (no application of both factors (T6) ) were used. According to the results, both  factors jasmonic acid and calcium had a positive impact on the examined cultivars, So that the Jelly had a better response rate than the other varieties. Amongst treatments, T1 in all traits except non-photochemical quenching had the highest average in all three cultivars. According to the results, it can be concluded that Jasmonic acid and calcium, reduced the adverse effects of thermal stress and nutrient deficiencies in both before and after stage of the rhizome production. In addition, higher positive effects obsorved when jasmonic acid and calcium compounds, were applied before the stage of the rhizome production.
