“…It has been reported that the effectiveness of elicitors is determined by the reactivity of the fruit tissues, which decrease with ripening progress [19]. In this study, the observed TSS concentrations were similar to those described by Kassem et al [40], in SA treated date fruit. However, Mohamed et al [10] reported no significant difference between SA treated and the control date fruit, in relation to TSS content.…”

“…The average weight, width, and length of Khesab fruit were significantly (p < 0.05) higher in SA and Ch+SA treatments as compared to control and other treatments. These improvements in fruit physical properties might be due to the influence of SA in combination with Ch in maintaining cells integrity and enhancing the strength and improving weight and size of the fruit [40]. Similarly, Mohamed et al [10] described that preharvest spray application of SA increased date fruit weight, width and length significantly compared to control fruit.…”

“…Also, Ca and SA were found to have significantly lower weight loss compared to control in constant to Atia et al [44] reported that pre-storage treatment with Ca and SA reduced weight loss in 'Barhi' dates at Khalal stage. Also, Kassem et al [40] and Mohamed et al [10] found that the preharvest application of SA reduced weight loss during storage in treated 'Khesab' fruit compared to the control. SA is well known to reduce chilling injuries, inhibit ripening, and act against various abiotic and biotic factors [45].…”

“…Weight loss is a significant factor that reduces postharvest fruit storage life and marketability [10,40]. Figure 1 presents the percentage of weight loss occurred during cold storage at 2 • C and 90-92% RH for 60 days in harvested fruit.…”

“…Calcium application is well known for slowing the rate of respiration and delaying fruit ripening [26][27][28]. Similarly, the preharvest application of SA delayed date fruit ripening by three weeks compared to the control fruit [40]. In addition, pre-and postharvest treatments with SA have been reported to improve quality, shelf life, and prevent deterioration in many fruit [20,26,48].…”

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

et al. 2021

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.
