Evaluating salt tolerant genotypes and vegetative growth characteristics of sour cherry Prunus mahaleb as affected by sodium chloride NaCl levels Somayeh Tahsiri s tahsiri@ag iut ac ir October 2012 Department of Horticultural Science Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Assoc Prof B Baninasab bbanin @cc iut ac irSupervisor Assist Prof E Ganji Moghadam eganji@hotmail comAbstract Salinity is one of the greatest factors that limit the growth of plants and production of crops Thistopic has been of utmost importance since long ago Current reports show that this problem isincreasing Cherries are plants which are sensitive to salt The usual method to propagate cherries isproducing of seedlings and grafting of suitable scion on rootstock Cherry trees are mostly cultivatedin flat areas where salinity may arise because of over fertilization and irrigation with low qualitywater The salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks Therefore according to the above mentioned limitations a greenhouse study was arranged to assessthe salt tolerance of eight sour cherry Prunus mahaleb genotypes A factorial experiment throughcomplete randomized design CRD with four replications and four levels of salt including 0 20 40and 60 mM NaCl with electrical conductivity of 1 294 3 135 5 383 and 6 564 dsm 1 were used Byincreasing the levels of salt visible damage plant height and stem diameter fresh and dry weight relative water content RWC relative chlorophyll chlorophyll florescence Fv Fm photosyntheticrate A stomata conductance gs transpiration E and potassium of root decreased Being salty alsoincrease electrolyte leakage substomal chamber containing Co2 Na concentration in leave and root K of leave and Na k of leave and root The result of comparison of the mean of growth parametersshowed that there is a significant difference between various genotypes of sour cherry Among ofgenotypes 249 121 and 255 had the least and 139 188 and 120 showed the most decrease in growthindexes of shoots and roots The most RWC was in the 249 respectively The least and mostelectrolyte leakage was seen in 139 and 249 respectively About the relative chlorophyll content andchlorophyll fluorescence 249 had the most and 255 and 139 had the least amount respectively Themost amount of proline content was observed in 187 however 255 possessed the least amount of leafproline Related to gas exchange indexes 249 had the least changes compared to control but 120 139and 188 had the greatest amount of decrease The interaction effect of salt and genotypes showed thataccumulation of Na in leaves and roots was less in 121 and 139 The amount of K in the leavesdecrease in the low level of salt 20 mM and increase in high levels of salt 120 owned the mostwhile 255 owned the least amount of potassium in their leaves The amount of potassium in the rootdecrease in according with the increase of salt The most amount of potassium in root was observed in277 and 139 accumulated the least amount of potassium in their roots Based on the results it wasfound out that 249 277 121 and 187 genotypes was more resistant to changes in the level of salt But 120 139 188 and 255were the most sensitive ones to salt Key Words Sour cherry Prunus mahaleb Genotypes Salinity
