EFFECT OF METHYL JASMONATE APPLICATION ON BIOACTIVE CONTENTS AND AGRO-MORPHOLOGICAL PROPERTIES OF STRAWBERRY FRUITS

In this study, methyl jasmonate were applied to strawberry cultivars, and the pomological and biochemical characteristics of the fruits were investigated. The highest increase in fruit weight was determined in the Honeoye cultivar and it was detected in the application of 0.50 mM MeJa according to the control group. When the organic acid contents of fruits were examined, it was determined that the dominant acid was citric acid and the maximum range (Control: 1.49 g kg–1; 0.50 mM MeJa: 16.49 g kg–1) was in the Seascape cultivar. When the ellagic acid content of the fruits was examined, the highest increase (Control: 13.350 mg 100 g–1, 0.25 mM MeJa: 22.768 mg 100 g–1) was found in the Sweet Ann cultivar. In this study, it was determined that appropriate concentrations of MeJa should be preferred in cultivation of strawberry and these concentrations affected the fruit quality parameters.
