Cover Story: An oxidative stress occurred during the first hours of acclimatisation of stevia plantlets to ex vitro conditions. After 2 days, DHAR was higher than MDHAR. After 7 days, plants activated the MDHAR route to recycle ascorbate, which is much more efficient energetically, and SOD and CAT activities peaked, suggesting a protection against ROS. Peroxidase showed a 2-fold increase after 2 days of acclimatization, remaining high until day 14, linked to the cell wall stiffening and the lignification processes. A progressive increase in the photochemical quenching parameters and the ETR occurred, indicating a progressive photosynthetic efficiency during this process. Antioxidant enzymes, lipid peroxidation, and chlorophyll fluorescence are proven as suitable tools for the physiological evaluation during acclimatization to ex vitro conditions. View this paper.
