Abstract
Various treatments are carried out in order to extend both the shelf life and storage life of fresh fruit and vegetables after harvest and among them non-toxic for humans, environmentally and economically friendly alternative treatments are gained more importance. In the current study, methyl jasmonate (MeJA), cytokinin, and lavender oil which are eco-friendly and safe for human health were applied on apricot fruit. The treated fruit were stored at 0 °C and 90–95% relative humidity for 25 days and catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) enzyme activities and lipid peroxidation of apricots after treatments were studied. According to the findings obtained from the study, it was observed that 5 ppm cytokinin and 1000 ppm lavender oil treatments of apricot fruit gave better APX and CAT enzyme activity, respectively. In addition, better SOD enzyme activity in fruit was obtained with MeJA + lavender oil treatments. As a result, it can be emphasized that the product quality of apricot fruit is preserved as both the eco-friendly application of MeJA, cytokinin, and lavender oil separately from each other and the treatment of combinations between these compounds activate the enzymatic antioxidant defense systems of apricot fruit after harvest.

An increase in ascorbic peroxidase (APX) enzyme activity was observed in general considering all treatments compared to the beginning of storage, but higher enzyme activity was observed in the treated fruit samples (Table 1)
It was determined that the treatments of methyl jasmonate (MeJA), cytokinin, and lavender oil, which are environmentally friendly and safe for human health, have positive effects on antioxidative enzymes (CAT, superoxide dismutase (SOD), and ascorbate peroxidase (APX)) and lipid peroxidation in apricot fruit during the storage period
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Fruit and vegetables are a huge portion of the food supply chain and are depended on globally for good health and nutrition. The supply of good food, greatly depends on good pre and postharvest handling practices. Substantial research has been carried out to preserve the quality of fresh horticultural produce. Eco-friendly technology for pre and postharvest produce quality presents the scope of emerging eco-friendly technologies to maintain the postharvest quality of fresh produce in terms of safety and nutrition [1,2,3,4,5,6]
