“…Thus combination of pre‐ and postharvest treatments of strawberry with SA decreased fungal decay and maintained overall quality during storage . Similarly, preharvest foliar sprays of jujube plants with 2.0 mmol L −1 SA decreased decay caused by Alternaria alternata and Monilinia fructicola at harvest, and this effect persisted and was also evident during cold storage . Moreover, SA ASA or MeSA treatment of sweet cherry trees, at 0.5, 1.0 and 2.0 mmol L −1 concentrations, applied at pit hardening, initial colour changes and onset of ripening, increased fruit quality attributes such as weight, firmness and content of total phenolics, total anthocyanins and antioxidant activity …”

“…Moreover, Maha, (2016) worked on grapefruit, and delayed the properties change of fruits by coating with paraffin oil, salicylic acid and Arabic gum and mentioned that these materials were useful for coating fruits to prolong marketing and storage period (shelf life with highest fruits quality ). EL-Mahdy et al, (2017) using balady orange fruits; reported that salicylic acid had a positive effect on fruit quality and decay of fruits treated with salicylic acid as single or combined with potassium sulphate In jujube plants, preharvest foliar sprays with 2.0mM of SA inhibited decay caused by Alternaria alternata and Monillinia fructicola at harvest, and the inhibitory effect persisted during long-term storage (Cao et al, 2013).…”

A field experiment was performed during growing seasons of 2016/2017 and 2017/2018 in a private orchard located at Kafr Shukr, Benha Center, Qualyubia Governorate, Egypt. The investigation was conducted on 50-years-old of Valencia orange trees (Citrus sinensis L. Osbeck) budded on sour orange (Citrus aurantium L.) rootstock. The treatments were T 1 : control treatment (sprayed with water). T2 and T3 : trees sprayed with potassium sulphate 1% and 2% .T4 and T5 : trees sprayed with salicylic acid at 100ppm conc. and 200ppm,respectivelyT6 and T7:trees sprayed with Oleic acid at250ppm and 500 ppm conc.; respectively.T 8 and T 9 :trees sprayed with phenylalanine at 200 ppm and 300ppm; respectively.T10: spraying trees with a mixture of (K2SO4 1%+SA 100 ppm + Oleic acid 250 ppm+Ph 200 ppm).T11:spraying trees with a combination of(K2SO4 2 %+SA200 ppm + Oleic acid 500 ppm + ph 300 ppm). The results proved that foliar application with a mixture of (K 2 SO 4 2% + SA200p pm + Oleic acid 500ppm +ph 300 ppm) produced significantly the highest fruit yield ; expressed as weight and significantly increased peel and pulp weights and fruit juice volume when compared with the control treatment and other foliar application treatments. Moreover, the aforementioned treatment; also improved fruit volume, fruit length. However, fruit diameter character was the highest by foliar application with Oleic acid at 500ppm concentration. This was true during both seasons of the study. As for fruit shape index, Oleic acid 500 ppm, ph 300 ppm treatment was significantly supremacy than other treatments in the both seasons. All treatments reduced percentage of weight loss, decay % during the storage period compared with the untreated fruits (control) during both seasons. Moreover, trees sprayed with a mixture of (K 2 SO 4 2%+ SA 200 ppm + Oleic acid 500 ppm + ph 300 ppm) significantly reduced fruit decay percentages and markedly increased fruit peel thickness compared with the control treatment (water spray) and all other treatments and the difference was significant. Vitamin C was decreased with prolonging the storage period of the fruits. All treatments reduced the loss of vitamin C in fruits during storage period compared with control. The acidity content was gradually decreased with the storage period during the investigated seasons. Vice-versa, fruit total soluble percent and TSS/acid ratio greatly increased with increasing storage period. Both total soluble solids % and vitamin C content in fruit juice were increased when trees sprayed with a mixture of (K2SO4 2%+ SA 200 ppm + Oleic acid 500 ppm + ph 300 ppm) followed by trees sprayed with Oleic acid at 500ppm concentration. Besides, fruit total acidity and TSS/acid ratio significantly augment by spraying trees with this treatment. In addition; foliar application with phenylalanine at 300ppm significantly enhanced the ratio of TSS/acidity of Valencia orange fruits.

“…Examination of relevant cell wall constituents provided additional information to explore the relationship between fruit firmness and disease severity which showed that relatively high protopectin contents, lower pectinase activity and postponed cellulase activity peak values may explain how the jujube cell retains its structural integrity. Protopectin constituted a network with the cellulose in the cell walls to form a cross‐linked mesh, held together by the formation of covalent bonds with pectin or ionic complexes and provided sites for lignin deposition and function as a structural barrier (Cao, Yan, Zhao, & Jiang, ; Djioua et al., ; Ribeiro et al., ). Along with a high content of protopectin and water‐soluble pectin, it was shown that the increase in cellulase activity was delayed significantly until 30–45 days after CHO and SCD treatments, and the peak values were lower than that of control fruit.…”

The efficacy of submicron chitosan dispersions (SCD) on Alternaria alternata rot of the ‘Lingwu changzao’ jujube (Zizyphus jujuba Mill. cv. Lingwu changzao) fruit and possible mechanisms involved were investigated in this study. When jujube fruit at the preharvest stage were sprayed twice with SCD (10 mg/ml) water solution and then natural infections were allowed to develop, there was a significant reduction in disease incidence and lesion index compared to control fruit during storage period, and similar results were obtained from postharvest fruit inoculated with the Alternaria rot pathogen. Scanning electron microscopy of the pathogen revealed that hyphae and spores were damaged and deformed when growing on the surface of fruit pretreated with SCD or CHO. The slowed softening of jujube fruit resulted from the protopectin content increasing compared with the control. Furthermore, SCD sprays inhibited cell wall hydrolysing enzymes, pectinase activity was decreased, and the increase in cellulase activity was postponed (from 30 days to 45 days).It was concluded that preharvest application of SCD was a more effective alternative to conventional chitosan for preventing postharvest from Alternaria rot of ‘Lingwu changzao’ jujube fruit.
