Abstract :This study was conducted to identify the effects of different doses insert ignore into journalissuearticles values(1120, 2240 and 4480 mg L -1 ); of methyl jasmonate insert ignore into journalissuearticles values(MeJA); treatments on apple fruit quality at the cold storage. In the study, 5 year-old Fuji apple trees grafted on M9 rootstock were used. MeJA was applied to the trees three different times insert ignore into journalissuearticles values(2, 3 and 4 weeks before the commercial harvest date);.  It has been determined that the effect of MeJA treatment on weight loss during cold storage has changed depending on the concentration of MeJA.  With the increase in application dosage of MeJA, the fruit fresh softening significantly delayed. The fruits treated with MeJA have higher soluble solids content insert ignore into journalissuearticles values(SSC); and titratable acidity during cold storage. W hile the fruits treated with MeJA had lower pH values, no significant effect of MeJA treatment on starch index was observed. As a result, it was determined that fruit flesh firmness loss that occurs during cold storage can be delayed by MeJA treatment.
