Water distribution and ionic balance in response to high CO 2 treatments in strawberries (Fragaria vesca L. cv. Mara de Bois)

Highlights: ► CO2 treatments controlled weight loss and retained cell structure in strawberries compared with air. ► 20% CO2 increased cell water retention, but 40% resulted in intercellular spaces filled with aqueous solution. ► 20% CO2 maintained K+/Na+ ratios similar to those in freshly harvested...

Mara de Bois) stored at 0°C. Intercellular water distribution and cellular tissue integrity were visualized using low temperature scanning electron microscopy (LT-SEM). The results indicated that high CO 2 treatments prevented the weight loss and cell structure disorganization observed in untreated strawberries. However, there were differences in water loss regulation dependent on CO 2 levels. In addition to mediating osmotic adjustment, treatment with 20% CO 2 had a protective effect on cellular structure and prevented the movement of water into the intercellular spaces. Specifically, an accumulation in total sugars and proline were detected in 20% CO 2-treated fruit. Moreover, water loss was controlled in these fruit and K +/Na + homeostasis maintained similar to that found in freshly harvested fruit. By contrast, 40% CO 2 controlled water loss, but the intercellular spaces were filled with aqueous solution, possibly as a result of a change in water status. Moreover, these changes were associated with an increase in free soluble Ca 2+. In view of the opposite patterns of accumulation in malic, succinic acid, γ-aminobutyric acid (GABA) and glutamate found when comparing 20% and 40% CO 2 treated strawberries, we suggest that their corresponding metabolic pathways play a regulatory role in CO 2 tolerance.This work was supported by CICYT Project AGL2008-02949.
