“…Our results indicated that MJ treated blackberries maintain higher TFC and TPC, possibly due to lower production of H 2 O 2 and MDA, with higher activities of CAT and SOD enzymes. These ndings are aligned with previous reports showing that MJ application has the potential to maintain relatively higher secondary metabolites in both Chinese bayberries(Wang et al 2009) and strawberries (Ayala-Zavala et al 2005).MJ is an endogenous phytohormone that activates stress mediated antioxidant activities in fruits and vegetables, participating in the suppression of ROS metabolism(Zhu et al 2022). In the present study, MJ induced earlier ROS signalling in blackberries at harvest, as compared to control (Table2).…”

“…In the present study, higher AsA and GSH contents (Table 3) in MJ treated fruit could be explained by delayed accumulation of free radicals and mitigated activities of oxidative enzymes, such as PPO and POD. Previously, MJ has been reported to maintain better fruit quality and higher levels of AsA and GSH levels in peaches by suppressing POD activity and ROS accumulation (Zhu et al 2022).…”

Red drupelet reversion (RDR) shortens the marketing window for blackberries by reducing cosmetic appearance of the fruit. Blackberry plants were sprayed with methyl jasmonate (MJ 0, 1, 2 or 3 mM), two weeks before tentative harvest maturity, to evaluate effects on RDR, antioxidant capacity and fruit quality in cold stored blackberry fruit for up to 12 days. MJ significantly reduced RDR while maintaining higher anthocyanins, phenolics and flavonoids during cold storage for 12 days. Fruit treated with 1 mM MJ showed higher total antioxidants, ascorbic acid, and glutathione content. Additionally, MJ treated raspberries displayed higher activities of superoxide dismutase, catalase, ascorbate oxidase, monodehydroascorbate reductase, dehydroascorbate reductase and glutathione reductase enzymes, than controls for 12 days. In conclusion, the preharvest spray application of MJ (1 mM) has the potential to reduce RDR, improve antioxidant capacity and maintain fruit quality of cold stored blackberries.

Fruit decay and deterioration in overall quality are the main problems of preserving peaches after they are harvested. In this article, the outcomes of 1‐MCP combined with polylysine atomization on Xinjiang flat peaches were evaluated. Distilled water atomization treatment, 1,000 mg/L polylysine atomization treatment for 10 min and 1,000 mg/L polylysine atomization treatment for 20 min were employed. Results showed that the combined treatment using 1‐MCP and polylysine helped to delay the fruit decay rate, respiration, ethylene production, respiration intensity, organic acids, soluble solids, hardness, and microorganisms. Furthermore, reactive oxygen metabolism of O2− and OH− was inhibited. A combined treatment can effectively improve the antioxidant capacity during almond storage, and thus improve shelf life. Therefore, 1‐MCP combined with polylysine atomization treatment is necessary to control fruit rotting and to extent the storage life.

“…‘Jinxiu’), originated in Hunan province of China, is the national product of geographical indication. It is favorable among consumers because of its high commercial value with bright color, palatable taste, rich nutrition, and so on (Zhu et al., 2022). In the past few years, not only the yellow peach cultivation areas but also the yields have continued to grow.…”

This study aimed to analyze the effect of 1‐methylcyclopropene (1‐MCP) treatment on the postharvest quality, epidermal wax morphology, composition, and gene expression of Jinxiu yellow peach during cold storage. The results showed that 1‐MCP treatment could maintain the postharvest quality of peach fruit as compared to control (CK) during cold storage. The wax crystals of peach fruit were better retained by 1‐MCP, and they still existed in 0.6 and 0.9 µL/L 1‐MCP treated fruit at 36 days. The total wax content in all the fruit increased first and then decreased during cold storage. Meanwhile, n‐alkanes and primary alcohols were the main wax components. Compared to CK, 1‐MCP treatment could delay the reduction of wax content during cold storage. The correlation analysis indicated that the postharvest quality of yellow peach was mainly affected by the contents of fatty acids and triterpenoids in cuticular wax. The transcriptomics results revealed PpaCER1, PpaKCS, PpaKCR1, PpaCYP86B1, PpaFAR, PpaSS2, and PpaSQE1 played the important roles in the formation of peach fruit wax. 1‐MCP treatment upregulated PpaCER1 (18785414, 18786441, and 18787644), PpaKCS (18774919, 18789438, and 18793503), PpaKCR1 (18790432), and PpaCYP86B1 (18789815) to deposit more n‐alkanes and fatty acids during cold storage. This study could provide a new perspective for regulating the postharvest quality of yellow peach in view of the application of cuticular wax.Practical Application‘Jinxiu’ yellow peach fruit is favorable among consumers because of its high commercial value. However, it ripens and deteriorates rapidly during storage, leading to serious economic loss and consumer disappointment. The effect of 1‐methylcyclopropene (1‐MCP) treatment on the postharvest quality, epidermal wax morphology, composition, and genes regulation of ‘Jinxiu’ yellow peach during cold storage was assessed. Compared to control, 1‐MCP treatment could retain the storage quality of yellow peach by affecting cuticular wax composition and gene expression. This study could provide new perspective for regulating the postharvest quality of yellow peach in view of the application of cuticular wax.
