Resumo
The chemical composition of essential oils was used to study the spatial structure of eight
Eugenia dysenterica populations in central Brazilian Cerrado. Variation partitioning using
spatial and environmental data sets as predictors was highly significant and explained 7.8 and
8.1% of oil chemovariations, respectively. Results suggested that essential oil polymorphism was
genetically rather than environmentally determined. Furthermore, the intercept of the multivariate
Mantel autocorrelogram between the distance matrices of oil constituents and sampling sites
suggested that the populations differ chemically whenever geographical distance exceeds 120 km.
It stands, therefore, as an alternative indicator of the minimal distance between samples required
for conserving the genetic diversity of populations.
