Abstract: Since strawberry plants (Fragaria×ananassa Duch.) are susceptible to salinity, therefore a reduction of negative effects of salt stress is needed in strawberry production. To investigate the interaction effects of paclobutrazol (PP ) and salinity on fruit yield, leaf mineral elements and free proline content, three levels of 333 NaCl [0, 5, 10 mM] were incorporated into the nutrient solution and four levels of PP [0, 10, 20, 30 mg LG ] 333 1 were sprayed. Interaction of PP in 2 levels (20 and 30 mg LG ) with 5 mM NaCl, showed increase in fruit yield. 333 1 10 mg LG1 of PP reduced proline content at 5 mM NaCl salinity. 20 mg LG1 of PP at 5 mM NaCl caused 333 333 reduction in shoot sodium content. Similar result was also observed in the interaction of 20 and 30 mg LG1 of PP with 10 mM NaCl. PP application also reduced root sodium content. All levels of PP at 5 mM NaCl and 333 333 333 20 mg LG1 of PP at 10 mM NaCl, increased shoot potassium content. PP could overcome the increase in 333 333 shoot and root chlorine content at 5 and 10 mM NaCl. PP application decreased the electrolyte leakage 333 induced by salinity at 5 and 10 mM. From the above results, effective role of PP on fruit yield promoting and 333 reducing damages of sodium and chlorine ions on strawberry plant has been proved.
