The study aims to investigate the effectiveness of an encapsulated powder containing savory essential oil and calcium propionate salt on reactive oxygen species (ROS) and the expression of antioxidant genes (SOD, APX, CAT) in pear seedlings (cv. Spadona) inoculated with E. amylovora (ATCC 49946). To this goal, firstly, the antioxidant activity of 7 types of herbal essential oils (T. daenensis, T. vulgaris, S. hortensis, Z. multiflora, M. spicata, O. majorana, and T. ammi), with 10 types of different organic acid salts ) calcium acetate, calcium lactate, calcium citrate, calcium propionate, potassium acetate, potassium lactate, potassium citrate, magnesium acetate, magnesium lactate, and magnesium citrate) were separately evaluated in the laboratory. Next, the most effective candidates (calcium propionate salt + S. hortensis essential oil) were capsulated in maltodextrin and modified starch by spray drying technique. To evaluate the efficiency of the encapsulated powder, the greenhouse experiment was designed using a Randomized Complete Block Design (RCBD) with six treatments. The findings demonstrated that increasing the concentration of the encapsulated powder treatment led to a relative increase in the expression of the antioxidant genes (SOD, APX, CAT) compared to the reference gene (GAPDH). The highest effect on SOD, APX, and CAT gene expression was seen in the third treatment (T3), while the first treatment (T1) had the lowest effect. Additionally, T1, T2, and T3 treatments decreased the amount of Malondialdehyde (MDA), but these treatments led to a relative increase in total phenolic content (TPC) in the pear leaves compared to the control treatment.
