Essential oil variability in Eugenia dysenterica fruits

Abstract

Essential oils (EOs) of Eugenia dysenterica fruits from seven populations were assessed using GC/MS and chemometric analysis. Variations in EOs between populations and three operational chemical units (OCUs), combined with foliar Mn²⁺ as an environmental variable, indicate that 86.8% of variation in oils was explained by these predictors. Variance partitioning shows that the largest pure contribution was attributed to foliar Mn²⁺ (13.1%), followed by OCU (11.4%). Populational origin contributed with lowest variance (6.6%).
