AB  - BACKGROUND: In northern Iran and other cold regions, winter freezing injury and 
      resultant yield instability are major limitations to strawberry production. 
      However, there is scarcity of information on the physiological and biochemical 
      responses of strawberry cultivars to freezing stress. This study aimed to 
      investigate the physiological and biochemical responses of strawberry cultivars 
      (Tennessee Beauty, Blakemore, Kurdistan, Queen Elisa, Chandler, Krasnyy Bereg, 
      and Yalova) to different freezing temperature treatments (- 5, - 10, - 15, - 20, 
      and - 25  degrees C) under controlled conditions. RESULTS: All measured physiological and 
      biochemical features were significantly affected by the interaction effect 
      between low temperatures and cultivars. Tennessee Beauty showed the highest RWC 
      at - 25  degrees C. The highest Fv/Fm was observed in Queen Elisa. Krasnyy Bereg had the 
      least freezing injury (FI) in crown and leaf, while Yalova and Chandler showed 
      the highest crown and leaf FI, respectively. At - 20 to - 25  degrees C, the highest 
      carbohydrates contents of crown and leaf were noted in Blakemore and Krasnyy 
      Bereg cultivars, respectively. The Yalova showed the highest protein content in 
      both crown and leaf tissues at - 25  degrees C. The Tennessee Beauty and Blackmore 
      cultivars showed the highest proline in crowns and leaves at - 15  degrees C, 
      respectively. The highest ThioBarbituric Acid Reactive Substances (TBARS) 
      contents in the crown and leaf were observed in Kurdistan and Queen Elisa, 
      respectively. Queen Elisa and Krasnyy Bereg cultivars showed SOD and POD peaks in 
      the crown at - 15  degrees C, respectively. CONCLUSION: Freezing stress was characterized 
      by decreased Fv/Fm and RWC, and increased FI, TBARS, total carbohydrates, total 
      proteins, proline content, and antioxidant enzyme activity. The extent of changes 
      in above mentioned traits was cultivar dependent. FI and TBARS were the best 
      traits among destructive parameters for evaluating freezing tolerance. Moreover, 
      maximum quantum yield of PSII (Fv/Fm index), as non-destructive parameters, 
      showed a significant efficiency in rapid assessment for screening of freezing 
      tolerant strawberry cultivars. The cultivars Krasnyy Bereg, Queen Elisa, and 
      Kurdistan were the most tolerant cultivars to freezing stress. These cultivars 
      can be used as parents in breeding programs to develop new freezing tolerant 
      cultivars.
