“…An alternative approach is the application of natural elicitors to enhance physiological adaptations and accelerate the plant's defense system [15,16]. Various studies on pre and postharvest applications have gained success in different fruit crops by using eco-friendly elicitors such as chitosan [9,[17][18][19][20], salicylic acid [10,[21][22][23][24][25], and calcium chloride [26][27][28], retarding tissue softening, delaying ripening, enhancing quality, extending shelf life, and preventing fruit deterioration. Chitosan is one of the most recognized natural elicitors known for its antimicrobial, eliciting, and film forming characteristics [16,19].…”

“…Another natural elicitor is salicylic acid, which is a simple phenolic phytohormone with various roles in plant growth and developmental processes. Pre/post-harvest treatments with salicylic acid can dramatically enhance the quality and shelf life, and prevent deterioration in many fruits [10,[21][22][23][24][25]. These elicitors exert their effects by employing different mechanisms such as triggering the synthesis of phytochemicals, enhancing the production of particular antioxidant enzymes, and reducing ethylene production in vegetables and fruit [15,19,29].…”

Synergistic Effect of Preharvest Spray Application of Natural Elicitors on Storage Life and Bioactive Compounds of Date Palm (Phoenix dactylifera L., cv. Khesab)

Despite the immense capabilities of the date palm, maintaining the fruit’s quality, marketability, and shelf life is still a challenge. This study aimed to assess the synergistic effect of a preharvest spray application of a natural elicitor chitosan, (Ch) 1% alone and in combination with salicylic acid (SA) 2 mM and calcium chloride (Ca) 3%; (Ch,SA, Ca,Ch+Ca, Ch+SA, Ch+SA+Ca), on the quality parameters, storage life, and bioactive compounds content of date fruit from ‘Khasab’ cultivar during cold storage for 60 days. The obtained results revealed that all treatments significantly retard senescence/decay of the fruit compared to the control. Ch+SA treated fruit followed by Ch, and Ch+SA+Ca had the lowest weight loss, color change, and the least decay after 60 days of storage. Ch+Ca, SA, Ca treated fruit had significantly lower levels of total soluble solids and highest total phenolic, tannins, and flavonoids contents compared to the control fruit. Antioxidant activities were found in all treatments, with significantly higher effect in Ch+SA+Ca and Ch+SA compared to the control. Our results provide an evidence for a synergistic effect of elicitors combination to extend the shelf life of date fruit during cold storage by preserving its quality and decreasing senescence/decay and recommend it as a promising strategy.

“…It was reported that spraying apple trees with AVG four weeks before harvest delayed the fruit ripening rate and decreased PFD by 50% [ 12 ]. Preharvest application of SA also decreased PFD [ 62 ]. Chitosan slowed the cell structural degradation in the abscission zone by diminishing the function of cell-wall-degrading enzymes [ 63 ].…”

“…The high concentrations of SA and chitosan have substantially preserved fruit quality ( Figure 4 ). 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 ].…”

“…Both components improve plant antioxidant capacity and prevent cell-wall degradation through their positive effect on phenols and antioxidant enzymes [ 20 ]. It has been reported that SA effectively increases melatonin content, which has an antioxidant function, as a scavenging ROS, reducing membrane lipid peroxidation [ 62 ]. In addition, SA effectively improved the expression of cytosolic malate dehydrogenase and strengthened the plant cell’s redox state in apple [ 91 ] Chitosan protected membrane integrity by limiting the lipoxygenase activity and MDA accumulation [ 92 ].…”

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.
