a Lipid content in the pericarp (% dry matter) and b oil fatty acids composition, expressed as percentages of saturated, monounsatured and polyunsatured FAs (% total FAs content), estimated in green mature (GM) and turning purple (TP) drupes of ‘Carolea’ populations growing at different meters above sea levels (masl). The results were reported as mean values (± standard deviation) of three replicates. Significant differences are shown by different letters (P ≤ 0.001) (Students t-test)
