“…Potassium (K) is one of the most important macro-elements, especially for fruit trees, playing an essential role for plant growth and development. Many previous studies have investigated the effects of potassium on the yield and quality of fruit crops [8][9][10][11][12][13]. Potassium as foliar application is an effective, fast and high-efficiency mean to supply the tree with its nutritional needs in critical periods away from soil-cation interactions.…”

This is the first report to study the impacts of potassium sources on apricot fruit yield, quality and storability as a preharvest foliar application. Five sources of potassium (K-humate, K-sulphate, K-nitrate, K-silicate and K-citrate), plus water as a control treatment, were applied individually at 0.2% three times on ‘Canino’ apricot over the 2019 and 2020 seasons. The results showed that all potassium salts, applied foliarly, have potential to improve yield, fruit color, and some fruit physical attributes, such as: weight, size and firmness, as well as a reduced lipid peroxidation, accompanied by a low fruit malondialdehyde content reflected in a high tolerance during storage. The K-nitrate treatment was more effective in the improvement of fruit yield, preharvest quality parameters and keeping fruit postharvest quality characteristics from sharp decline during cold storage. Concerning fruit anatomy, K-nitrate and K-citrate showed thicker cuticle and epidermal parenchyma cell diameters, while the K-silicate induced the highest cell wall thickness. K-nitrate was the most economical, and could be recommended for apricot growers in the Nubaria region of Egypt.

“…It has been reported that the application of AVG significantly delayed starch degradation and reduced SSC, but enhanced acidity in sweet cherry [ 13 ], pear [ 21 , 34 ], and apple [ 12 , 22 ]. Similarly, SA was proven to delay the ripening and senescence process of plum [ 46 ], apricot [ 20 , 49 ], and mango fruit [ 40 ], represented by low SSC and high organic acid contents. Chitosan was also effective in improving the postharvest fruit quality of apricot [ 20 ], raspberry [ 25 ], and pomegranate [ 57 ].…”

“…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.
