Determination of Effect of Gibberellic Acid Treatments on the Fruit Quality of Strawberry Cv. Seascape

Abstract

In the study, the effect of gibberellic acid treatments on fruit quality of strawberry cv. Seascape grown in Bolu ecological conditions was examined. The fruit quality parameters were identified under the application of two concentration of GA3 (50 ppm and 100 ppm). It was determined that the values of SSC, pH, TA and fruit hardness were not statistically affected by both GA3 applications. The highest values related fruit weight and size were obtained at 50 ppm GA3 application. The SCC and firmness values were determined as 6.67 brix° and 1.31 kg/cm2 in 100 ppm concentration, respectively. The fruits treated with 50 ppm GA3 had lower pH than those treated 100 ppm GA3 and control. In addition, the highest fruit weight (46.01 g) and fruit acidity (1.11%) were obtained at the application of 50 ppm GA3. It was also found that the GA3 application did not cause a significant change in the flavor, taste and juice values. © 2017, Centenary University. All rights reserved.
