TY - JOUR TI - Methyl jasmonate treatments infuence bioactive compounds and red peel color development of Braeburn apple AB - The present study was carried out to determine the efects of methyl jasmonate (MeJA) treatments on the fruit peel colorparameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimentaltrees were treated with 1120, 2240, or 4480 mg L 1 MeJA at 1- and 2-week intervals between the 105th and 175th days of growth aferfull bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments didnot cause signifcant changes in chroma, except for in the fnal harvest in 2010, it decreased chroma values signifcantly on all samplingdates of 2011. Anthocyanin content, internal ethylene concentration, phenolic content, and antioxidant capacity increased linearlywith increasing MeJA concentrations, regardless of the application interval: MeJA treatments with 1-week intervals were found to be asefective as those with 2-week intervals. Although MeJA treatments increased ethylene biosynthesis, they did not cause any sofening;on the other hand, fruit frmness increased linearly with increasing MeJA concentrations. Preharvest MeJA treatments can be a goodmanagement strategy for red peel color development and fruit frmness preservation in Braeburn apples. Although both applicationregimes of MeJA signifcantly increased red color development, the treatments with 1-week intervals were found to be more efectivethan 2-week intervals with regard to phenolic content and antioxidant capacity.
