Abstract :In this study, the effect of methyl jasmonate insert ignore into journalissuearticles values(MeJA); treatments insert ignore into journalissuearticles values(10-3 and 10-5 M); and two different storage locations such as Ankara and Taşköprü, on some quality parameters, such as weight loss, L* values, soluble solids content, firmness, titratable acidity, total phenolic content, antioxidant capacity, vitamin C and allicin content in garlic bulbs insert ignore into journalissuearticles values(Allium sativum cv. ‘Taşköprü’); were investigated during a storage period of six months with three replications insert ignore into journalissuearticles values(30 bulbs or 120 g cloves);. Based on storage periods, storage locations and MeJA treatment effects, the results showed that the storage period significantly affected all parameters except allicin content. MeJA treatments positively affected weight loss, L* values, soluble solids content, total phenolics, and antioxidant capacity. At the end of the storage, the lowest weight loss was determined in 10-3 M MeJA as 7.8%, the highest L* value was 85.40 insert ignore into journalissuearticles values(10-5 M); and soluble solids content was maintained in 10-5 M MeJA insert ignore into journalissuearticles values(40.26%);. Higher total phenolics and antioxidant capacity were found in 10-3 M MeJA insert ignore into journalissuearticles values(24.44 mg 100g-1); and 10-5 M MeJA insert ignore into journalissuearticles values(66.88% I);, respectively. Moreover, warehouse location significantly affected L* values, titratable acidity, total phenolics While Ankara location caused the highest L* insert ignore into journalissuearticles values(86.07);, total phenolics insert ignore into journalissuearticles values(26.12 mg 100g-1);, and delayed increase in titratable acidity insert ignore into journalissuearticles values(0.89% citric acid); in samples, the highest values in allicin content insert ignore into journalissuearticles values(31.42 mg kg-1); was determined in samples stored in the Taşköprü location. Overall, MeJA treatment could be considered as promising treatment for long-term storage of bulbs in commercial warehouses.
