“…Furthermore, salicylate application increased anthocyanin synthesis and total antioxidant capacity, as in plum [22] and grape [23], although not apparent in tomato under certain conditions [24]. In line with these results, salicylate application stimulated the activity of phenylalanine ammonia lyase (PAL) and other enzymes involved in the phenylpropanoid biosynthetic pathway in blood orange [25], cherry [15], and goji berry [16], but not in pomegranate [26]. PAL sets the interface between primary and secondary metabolism, towards the production of a diverse range of metabolites (including anthocyanins), which are essential in orchestrating stress responses [27].…”

“…Lately, these compounds have received much attention since they mediate in signaling responses to abiotic and biotic stresses, inducing immunity both locally and in the whole plant by the systemic acquired resistance (SAR) against biotrophic pathogens [14]. Triggering the antioxidant enzymes activity for reactive oxygen species (ROS) detoxification and maintenance of redox homeostasis by salicylates has been presented in a number of research works for prevention of fungal decay, as in cherries [15] and goji berries [16]. Salicylates also effectively mitigate chilling injury symptoms [17,18], which are not relevant to the species under study.…”

Peel cracking and ostiole-end splitting (collectively termed cracking) are common disorders in ripe fig fruit, downgrading fruit quality and thus limiting marketability. This two-year field study addressed the possibility of alleviating cracking at harvest by two foliar salicylic acid (SA) sprays prior to harvest (8 and 5 d). Three SA concentrations (0, 1, and 2 mM) were employed in the first year, and based on the obtained results two (0 and 2 mM) in the second year. A local variety (‘Vasilika’) with excellent organoleptic profile, and high sensitivity to cracking was evaluated. Fruit was harvested at commercial maturity. Fruit marketability was mainly based on the incidence and severity of cracking. Fruit weight, peel color, flesh total soluble solids (TSS), titratable acidity (TA), and pH were estimated for fig quality. The contents of total anthocyanins (TAN), cyanidin-3-rutinoside (c-3-rut; the major anthocyanin in fig), and the expression of four genes coding for regulatory enzymes (phenylalanine ammonia lyase, anthocyanidin synthase, UDP-flavonoid glucosyl transferase 1, and UDP-flavonoid glucosyl transferase 2) of the phenylpropanoid biosynthetic pathway were also determined in the peel. Preharvest SA application (2 mM) increased the percentage of fruit without cracking (sound fruit) by 1.4–2.6-fold, and of marketable fruit (sound and slightly cracked) by 2-fold. SA application (2 mM) was associated with increased flesh TSS and TA, as well as with decreased flesh pH and peel red coloration in stripe. The treatment (2 mM SA) decreased both TAN and c-3-rut contents, which were highly associated (r = 0.978). Responses of transcription level of the four genes to SA application varied, and did not correlate with the other variables in the study. In conclusion, SA appears to be a low-cost and environmentally-safe agent for improving fig fruit quality and marketability, and facilitates harvesting and postharvest management of figs.

“…The role of SA could involve triggering the fruit’s local and systemic resistance to pathogens and their related proteins or polyphenols [ 62 ]. In addition, SA has a positive impact on the plant antioxidant system, as well as the phenylpropanoid metabolism cycle and its related genes, resulting in fruit rot inhibition [ 24 ]. It was also reported that SA affected DELLA proteins (class of nuclear growth-repressing proteins) that protect cells from a wide range of pathogens [ 71 ].…”

“…Foliar application of plant biostimulants [ 18 ], potassium [ 5 ], abscisic acid (ABA) [ 19 ], chitosan, oligochitosan, and salicylic acid (SA) [ 20 ] effectively reduces the deterioration rate and improves apricot fruit quality and storability. Preharvest foliar applications to control fruit diseases using aminoethoxyvinylglycine (AVG) [ 21 , 22 ], SA [ 23 , 24 ], and chitosan [ 25 , 26 ] have also been claimed to diminish ethylene production. In this aspect, transcriptome testing (RNA sequencing) has been used as a valuable tool to study the molecular mechanism of fruit quality changes in apricot [ 2 , 27 , 28 ], persimmon [ 9 ], kiwifruit [ 29 , 30 ], pummelo [ 31 ], and banana fruit [ 32 ].…”

“…The chorismate-derivative phytohormone, SA, is considered a natural phenolic acid [ 37 ] involved in plant growth and development [ 38 ]. It stimulates the defense mechanisms against various abiotic [ 24 , 39 , 40 ] and biotic stresses by inducing the accumulation of pathogenesis-related proteins [ 41 ]. Under stress conditions, SA has been shown to inhibit ethylene biosynthesis and its mode of action in plant [ 42 ] via the inhibition of the mitochondrial electron transport process [ 43 ], resulting in reduced respiration rate [ 11 , 44 ].…”

Ethylene plays a pivotal role in the climacteric fruit ripening and senescence process. The effect of three ethylene inhibitors on the yield, quality, and storability of ‘Canino’ apricot fruit was studied. Foliar sprays of distilled water (control), aminoethoxyvinylglycine (AVG) (150 and 100 mg·L−1), salicylic acid (SA) (4 and 2 mM), and chitosan (2.5% and 1.5%) were applied 30 and 15 days before harvest. Results indicated that the high concentrations of AVG and SA recorded the lowest percentage of preharvest fruit drop and, hence, the highest yield. Trees receiving either concentration of AVG showed the highest fruit firmness. High concentrations of all three ethylene inhibitors reduced fruit weight loss, total carotenoids, and soluble solid content (SSC), but increased total acidity (TA) during cold storage (2 °C). A high score of overall taste acceptability was observed with a higher concentration of SA, which was also recorded the lowest fruit malondialdehyde content (MDA) at harvest and during storage. The highest concentrations of SA and chitosan recorded no decay for 28 days of storage. Gene expression analysis reflected higher expression of PaACS1 gene with the highest concentrations of ethylene inhibitors, suggesting that SA (4 mM) is recommended for optimal yield, quality, and storability of ‘Canino’ apricot fruit grown under Egyptian conditions.

Abundantly available plants, animals, and microbes are excellent source of active substance to be used as fruit preservatives to delay postharvest fruit from decay, maintain good quality, and increase the shelf life. Although they are effective and free from toxicological risks, the use of the natural active products in agriculture is still limited due to the high cost of producing, complexity interaction in food matrix, and unacceptance of odor. This review focuses on employing naturally occurring bioactive compounds as an alternative to the synthetic preservatives used in fruit. For this purpose, natural compounds from abundantly available source, such as plants, animals, and microbes, are systematically described for their properties, mechanism of action, and applicability. Different postharvest handling of bioactive compounds and mechanism of their triggered/controlled release properties are discussed, especially with regard to challenge and future directions of these new strategy to preserve fruit in industry. This review offers a fundamental theory and technologies to develop the efficient and safe alternative strategies to synthetic fruits preservatives. Overall, the utilization of natural preservative techniques offers promising opportunities to maintain quality and extend shelf life of fruit, with potential applications in various industries such as vegetables, meat, and processed food.
