- Abstract
This study was carried out to determine the effects of postharvest salicylic acid (SA) applications on aroma components during the storage of “Roxana” apricot variety. In the study, salicylic acid at three different doses (0.5, 1 and 2 mM) was applied to the harvested fruits and compared with the untreated control group fruits. All fruits in the study group were pre-cooled for 1 day and stored in cold storage for 45 days under normal atmospheric conditions at 0±0.5°C and 90±5% relative humidity. In the research, soluble solid content (% SSC), titratable total acidity (% malic acid) and aroma component composition parameters were investigated at 15-day intervals, together with the initial analysis after harvest. In the study, 2 mM salicylic acid application came to the fore in all criteria and slowed down the ripening rate of fruits compared to other applications. Aldehyde, ester, ketone, lactone, alcohol and terpene aroma component groups were determined in the fruits of the “Roxana” apricot cultivar examined in the study. It was found that 1 and 2 mM SA applications in lactones and esters, which are component groups that contribute to the characteristic aroma of apricot fruits, contributed to the synthesis of these aroma components at the required level. Hexyl acetate component, which is in the ester aroma component group and is one of the major aroma components for apricot fruit, was initially determined at a value of 332.1 and its amount increased with the progression of maturity. At the end of the 15-day storage period, the highest increase in hexyl acetate component was detected in the control group, while the highest value was determined in the application of 2 mM salicylic acid with a value of 579.9 at the end of the 45-day storage period.
