Abstract :Apart from single and combined effect studies, priming stands out as a strategy that alleviates the effects of primary stress by inducing a mild oxidative stress through the administration of a priming agent prior to the actual stress. Arsenic (As) has a high potential to be found in agricultural lands, especially in irrigation water. In this study, tomato seedlings primed with different concentrations of boron (B) were subjected to 25 micromolar As application. At the end of the study, malondialdehyde (MDA) content, chlorophyll content, As accumulation, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APx) were analysed. The results showed that compared to the group treated with As alone, the groups treated with As+B significantly reduced the effects of stress up to a certain concentration. One of the significant findings was that arsenic accumulation decreased in all primed concentrations. This study demonstrates that boron priming at an appropriate concentration can be useful for cultivating plants resistant to environmental conditions, especially in arsenic-contaminated agricultural areas.
