Pre-Harvest Application of Salicylic Acid, Abscisic Acid, and Methyl Jasmonate Conserve Bioactive Compounds of Strawberry Fruits during Refrigerated Storage

Abstract

The short shelf-life and loss of bioactive compounds of strawberry fruit are the most important problems during strawberry refrigerated storage. This study was carried out to evaluate the effect of the pre-harvest foliar application of salicylic acid (SA) (2 and 4 mM), abscisic acid (ABA) (0.25 and 0.50 mM), and methyl jasmonate (MeJA) (0.25 and 0.50 mM) three times, 10 d apart, at fruit development and ripening stages on storage ability and bioactive compounds of strawberry fruit (cv. Festival) stored at 4 °C for 12 d. Our results showed that fruit obtained from both concentrations of ABA and 0.25 mM MeJA was firmer and had higher total soluble solids (TSS) than fruit from non-treated plants. However, all previous applications had no significant effect on weight loss, pH, or color. Applications of 4 mM SA and 0.25 mM MeJA conserved fruit from ascorbic acid (AsA) loss compared to control at the end of the storage period. In addition, all pre-harvest applications remained higher in total phenolic compounds (TPC) and anthocyanin contents compared to controls at the last storage period. Hence, the pre-harvest application of SA, ABA, and MeJA could be used to conserve TPC and anthocyanin as well as the quality of strawberry fruits during refrigerated storage.

Effect of Titanium and Vanadium on Antioxidants Content and Productivity of Red Cabbage

“…Anthocyanin (mg 100 g −1 ) was measured, as described by Darwish et al [19]. Briefly, the samples were extracted with 40 mL of ethanol to quantitatively evaluate anthocyanin content, then centrifuged for 20 min at 6000 rpm.…”

Pre-harvest application of proline, methionine, and melatonin improves shelf-life and maintains nutritional quality of Brassica oleracea florets during cold storage

“…Therefore, several researchers stated that pre and/or postharvest applications are needed to prolong shelf life and conserve florets' quality and nutritional quality after harvesting (Lai et al, 2011;Han et al, 2022;Elsayed et al, 2022). Various pre and postharvest materials have been used to increase the storability and delay the damage of Brassica floret such as utilization of methyl jasmonate (Darwish et al, 2021), melatonin (Onik et al, 2021), ozone and ultraviolet-C radiation application (Huyskens-Keil et al, 2012), and tapioca-starch edible coating (Owolabi et al, 2021). However, the application of some previous post-harvest treatments couldn't be applicable due to the high cost, low customer acceptance, or difficulty to apply.…”

Unravelling the Effect of Triacontanol in Combating Drought Stress by Improving Growth, Productivity, and Physiological Performance in Strawberry Plants

“…Strawberry ( Fragaria x ananassa) is considered one of the most important vegetables belonging to the Rosaceae family. The fruits of strawberries contain important minerals, fibres, vitamins (especially ascorbic acid), and antioxidant compounds such as pigments (anthocyanin), phenolic compounds, and carotenoids [ 1 , 2 ]. Additionally, it has been suggested that daily consumption of strawberries (10–454 g) could reduce the risk of cardiovascular disease and type II diabetes [ 3 ].…”
