Özet

This study was carried out in Tokat ecological conditions to determine the effect of methyl jasmonate (MeJA) and aminoethoxyvinylglicine (AVG), applied 3 weeks before anticipated harvest date, on fruit quality and biochemical content of '0900 Ziraat' sweet cherry (Prunus avium L.) grafted on Gisela 5 rootstock. In the study 100 and 200 mg L-1 AVG doses, and 2240 mg L-1 MeJA dose were used. Compared to control treatment, the fruit weight significantly increased with 100 mg L-1 AVG and MeJA treatment. Geometric diameter significantly increased with only MeJA treatment, whereas, flesh firmness significantly decreased with only MeJA treatment. The flesh / stone ratio increased with 100 mg L-1 AVG and MeJA treatment. L* and hue angle with 200 mg L-1 L AVG, chroma value with 100 mg L-1 AVG, and a* value with both AVG treatment significantly increased. The soluble solids concentration and pH value significantly decreased with MeJA treatment, whereas, the titratable acidity increased with MeJA. Total phenolic compounds and total anthocyanin significantly decreased with 100 mg L-1 AVG and MeJA treatment. The total antioxidant capacity significantly decreased with only MeJA treatment.
