“…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 ].…”

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.
