Teor de dilapiol em função do tipo de biomassa aérea em populações de Piper aduncum

Abstract

The aduncum has shown great commercial interest due to the content of dilapiolle present in the essential oil extracted from the aerial part , for this, the species has been studied and submitted to selections of material for breeding . Depending on the geographical distribution and adaptive capacity , presents great variability in production, including fresh and dry biomass . The aim of this study was to evaluate the yield and oil content in dilapiolle air , fresh and dry biomass in populations of P. aduncum . The performance data and content dilapiolle were subjected to analysis of variance , with comparison of means and linear correlation. Afterwards , discriminant analysis was used for the verification of population groups . The results showed that the yield of essential oil was higher for dry biomass and dilapiolle content did not vary as a function of biomass for populations 207 , 208 and 209 , which showed potential for selection for the breeding program of the species , in order to essential oil extraction in green biomass .
