Effect of Methyl Jasmonate, Cytokinin, and Lavender Oil on Antioxidant Enzyme System of Apricot Fruit (Prunus armeniaca L.)

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.

The Effect of Different Doses of 1-Methylcyclopropene on Postharvest Physiology and Predicting Ethylene Production through Multivariate Adaptive Regression Splines in Cocktail Tomato

“…Antioxidative enzymes such as APX, CAT, and SOD are involved in senescence, and the defense system plays a vital role in suppressing oxidative stress. The defense system protects cells from oxidative damage by preventing the accumulation of free oxygen radicals [23,42]. In previous studies, similar to the current study, it was determined that CAT, SOD, and APX enzyme activity was higher in 1-MCP-treated fruit, while MDA content was lower than in control fruit [43][44][45].…”

“…The activity of superoxide dismutase (SOD), catalase (CAT), and Ascorbate peroxidase (APX) enzymes was spectrophotometrically measured at 560, 240, and 290 nm, respectively [23]. The levels of lipid peroxidation were assessed as malondialdehyde (MDA) content [23].…”

“…A hydrogen peroxide assay kit and a superoxide anion assay kit (Nanjing Jiancheng, Nanjing, China) were used to measure the reactive oxygen species (ROS) level (H 2 O 2 and O 2 − ), respectively. The activities of antioxidant enzymes peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT) were determined according to a previous report [ 63 ]. The content of malondialdehyde (MDA) was measured by thiobarbituric acid (TBA) method to judge the stability of the plasma membrane [ 64 ].…”

The Effect of Methyl Jasmonate on Postharvest Physiology in Non-Climacteric Sour Cherry (Prunus cerasus L.)

“…For respiration rate determinations, fruit (each replication an average of 250 g) were kept at room temperature in closed jars for 2 hours and the carbon dioxide (CO2) emission of fruit was detected in headspace gas sample with the Headspace Gas Analyzer GS3/L analyzer. The respiration rate values presented as mL CO2 kg -1 h -1 (Cavusoglu et al 2020).…”
