Table 3: Relative percentage of volatile metabolites in apricot fruits analyzed via GC-MS, \(n\) = 3. For codes, refer to Table 1. Results are average of 3 independent replicates \(\pm\) std. deviation. * Different letters in the same line concerning _P- ammonical_ L. specimens indicate significantly different values (\(p<0.05\), Tukey’s test).
