“…2). Initially, ethylene production was present only in control fruit and the 1-MCP treatment was efficient in inhibiting ethylene production, as expected (Ekman et al, 2004;Lwin et al, 2021;Saquet, 2019;Xie et al, 2014). Interestingly, nanocoatings were also able to inhibit ethylene production as reported for other fruit (Guerreiro et al, 2017).…”

“…Therefore, fruit metabolic processes should be reduced without compromising their postharvest quality. Methodologies as the traditional cold storage at around 0 • C, the use of 1-methylcyclopropene (1-MCP) and controlled atmosphere storage, have been used to extend the storage life of pear (Ekman et al, 2004;Lwin et al, 2021;Saquet, 2019;Xie et al, 2014). Alternatively, it has been proposed recently the use of nanocoatings to preserve 'Rocha' pear with promising results (Gago et al, 2020).…”

“…The softening degree of fruit in SA, 1-MCP, and 1-MCP+SA groups were significantly lower than that in the control group. Previous studies have shown that when 1-MCP is used to treat Asian pears ( 25 ) and salicylic acid is used to treat goji berries ( 5 ), the firmness of the treated fruit is higher than that of the untreated fruit during shelf life. This finding is consistent with our results.…”

Incorporation of 1-methylcyclopropene and salicylic acid improves quality and shelf life of winter jujube (Zizyphus jujuba Mill. cv. Dongzao) through regulating reactive oxygen species metabolism

Winter jujube fruit is susceptible to aging, peel reddening, dehydration, shrinkage, and tissue softening during shelf life after it is removed from the cold storage conditions. In this study, the effects of 1-methylcyclopropene (1-MCP) and salicylic acid (SA) on the quality of winter jujube fruit during shelf life were investigated by measuring physiological indexes and the activities of antioxidant enzymes and enzymes related to reactive oxygen species (ROS) metabolism of winter jujube fruit. The results showed that 1-MCP treatment and SA treatment suppressed weight loss, respiratory rate, malondialdehyde (MDA) content, H2O2 content, and O2-· production rate, but improved firmness, color difference (ΔE), soluble solid content (SSC), titratable acidity (TA), superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), phenylalanine ammonia-lyase (PAL) activities, ascorbic acid content, glutathione content, total phenolic content, and total flavonoid content in comparison with the control. Particularly, the combined treatment of 1-MCP and SA (1-MCP+SA treatment) showed the maximum efficacy compared to the 1-MCP treatment and SA treatment alone. 1-MCP+SA treatment exhibited the best preservation effect, followed by SA treatment and 1-MCP treatment. Thus, the combined treatment of 1-MCP and SA is an effective approach to maintain the postharvest quality of winter jujube fruit and extend the shelf life.

“…To date, attempts to extend shelf life and reduce quality loss have been widely explored in pears, and several effective techniques, including low temperature, 1-MCP, controlled atmosphere/modified atmosphere packaging, phytohormones, and edible coatings, have been utilized to extend postharvest storability and maintain fruit quality [9][10][11][12][13][14]40]. For example, postharvest fumigation in fruits of several pear cultivars effectively reduced the fruits' respiration and substantially suppressed their quality deterioration, including acid metabolism, weight loss, flesh firmness, and browning during the post-storage ripening period [4,12,41,42]. Modified atmosphere packaging reduced ethylene production, ascorbic acid degradation, and cell membrane peroxidation and increased the storage life of 'Doyenne du Comice' (P. communis) pears by up to 2 months [43].…”

Postharvest ripening of sand pear fruit leads to quality deterioration, including changes in texture, flavor, and fruit color. Salicylic acid (SA), an important defense-related hormone, delays fruit ripening and maintains fruit quality, but the underling mechanism remains unclear. Herein, we evaluated the efficacy of SA in delaying the ripening process of Pyrus pyrifolia cv. ’Hosui’ pear fruit, as evidenced by the reduction in fruit weight loss, inhibition of firmness loss, cell wall degradation and soluble sugars, and retention of total phenols. Based on comparative transcriptomic data, a total of 3837 and 1387 differentially expressed genes (DEGs) were identified during room-temperature storage of control fruit and between SA-treated and control fruit, respectively. Further KEGG analysis revealed that the DEGs were mainly implicated in plant hormone signal transduction, starch and sugar metabolism, and cell wall modification. Moreover, exogenous SA treatment also altered the expression of many transcription factor (TF) families, including those in the ethylene-responsive factor (ERF), NAM, ATAF, CUC (NAC), basic helix-loop-helix (bHLH), basic leucine zipper (bZIP), and v-myb avian myeloblastosis viral oncogene homolog (MYB) families. Together, the results offer important insights into the role of SA-responsive genes in controlling fruit ripening in sand pears.
