“…Pre-harvest GA 3 treatments increased the weight of apricot fruit (Southwick et al, 1997) and the diameter, coloring, TSS content, and flesh firmness of peaches and nectarines (González-Rossia et al, 2007;García-Pallas et al, 2001;Coneva & Cline, 2006;Cetinbas & Koyuncu, 2013). It was reported that GA 3 treatments in several citrus species led to a delay in peel aging, softening, and deterioration as well as a decrease in the risk of disease (El-Dtmani & Coggins, 1991;Garcia-Luis et al, 1992;Pozo et al, 2000;El-Dtmani et al, 2000;Tumminelli et al, 2005;Sen et al, 2009Sen et al, , 2013.…”

The research work aimed at investigating the effect of pre-harvest gibberellic acid (GA 3 ) treatment on the quality of 'Dbilnaja' and 'Black Star' Japanese plum varieties. GA 3 was sprayed onto the trees during the fruit color break at 0, 25, 50, 75, and 100 ppm concentrations. After pre-cooling, the plums were placed in modified atmosphere packages and exposed to the following conditions as follows: short storage-transportation (ST) [20 days at 2 °C and 90% relative humidity (RH)]; distribution center (DC) (5 days at 6 °C and 80% RH), and shelf life conditions (SL) (2 days at 20 °C and 70% RH). Pre-harvest GA 3 treatments increased the fruit weight and size. Treatment of GA 3 at 50, 75, and 100 ppm increased the fruit flesh firmness and total soluble substances (TSS) values in both the plum varieties during storage, transport, and marketing; it also limited the weight loss during the marketing process. Treatment of GA 3 had no significant effects on the color, titratable acidity (TA), and the total phenolic and antioxidant activity values of plums. Pre-harvest GA 3 treatment at 50 ppm GA 3 can be thus recommended for both the plum varieties due to its effect on the fruit quality.

“…Exogenous plant growth regulators significantly reduced fruit drop and increased fruit weight, juice percentage, total soluble solids, acidity, and vitamin C content [ 11 , 13 ]. In addition, GA 3 delayed maturity/senescence and decreased postharvest losses recorded in ‘Kinnow’ mandarin [ 14 , 15 ]. Mcdonald et al [ 16 ] reported that GA 3 treatments enhanced peel oil while having no impact on fruit quality.…”

The citrus industry loses a significant amount of mandarin fruits either before or shortly after harvesting due to rind disorder. Different citrus cultivars are impacted by a physiological rind disorder that lowers fruit quality and marketability. Although the primary etiology of this condition is unknown, changes in relative humidity (RH) and rind water status can make it worse. The damage is initiated in the fall, especially following rain. It begins with irregular water-soaked areas that develop into dark-brown, necrotic lesions covering large portions of the fruit’s surface. The damage is evident in some citrus types such as Satsuma Owari mandarins and other cultivars. In this study, we attempted to understand and control the occurrence of this kind of rind disorder in Satsuma Owari mandarins growing under California conditions. Our data showed that fruit located in the outer part of the canopy suffer more than fruit in the interior canopy. We were able to reduce this damage in Satsuma Owari mandarins by applying 2,4-dichlorophenoxyacetic acid (2,4-D) at 16 milligrams/Liter (mg/L), gibberellic acid (GA3) at 20 mg/L, or Vapor Gard® at 0.5 percent (v/v) at the color break stage. However, GA3 caused a delay in color development by approximately four weeks. GA3-treated fruit changed their color completely four weeks after the control, and the rind damage was at a very low percentage. Delaying rind senescence could be a good strategy to reduce the damage in mandarin orchards. Data showed that in addition to the benefits of the different treatments on preventing rind disorder at harvest, they have some beneficial effects during storage for four weeks either at 0.5 or 7.5 °C.
