Abstract

Since the photochemical mechanisms of iodine-mediated adaptation to salt stress is not yet clear, the present study was performed to address this issue. STRAWBERRY (Fragaria × ananassaDuch.) plants were grown under controlled conditions, and soils of iodine treatment were fertilized with potassium iodate (KIO3) (5 and 50 mg/kg soil) before filling the pots. Salt stress (50 mM) negatively affected protein synthesis and photochemical reactions of STRAWBERRY, as evaluated by a decrease in performance index (PIabs) as well as higher levels of hydrogen peroxide (H2O2) and malondialdehyde, whereas application of KIO3 (at both 5 and 50 mg/kg) alleviated the detrimental effect of sodium chloride (NaCl) stress. Plants treated with 50 mg/kg showed an increase in the soluble sugars content with respect to no KIO3 supply under salinity stress. In saltstressed plants, the OJIP chlorophyll fluorescence curve showed a quicker fluorescence decrease in the I-P phase. Notably, I-P phase in plants treated with KIO3 was increased.These results indicated that KIO3 application could protect the photosystem II from damage under salinity stress. Additionally, application of KIO3 raised free radical scavenging activities of STRAWBERRY leaf because of an enhancement of catalase activity.These data provided the first evidence that the root-applied KIO3 pretreatment alleviated salt stress in STRAWBERRY by decreasing reactive oxygen species production, resulting in better PHOTOCHEMICAL FUNCTIONing under salt stress.
