Resumo
Araucaria angustifolia is a dioecious plant, which is endangered due to their
extensive exploitation and reforestation difficulties related to its slow
development and lack of methods for determining the sex of the plant before
its reproductive age (15 to 20 years). Through analysis of 1H HR-MAS NMR
and multivariate analysis was possible to propose a method to predict the
sex of the plant still young, by assessing the metabolic profile of fresh leaves.
This analysis led to the identification of regions of spectrum with higher
influence on differentiation between males and females, although the
corresponding metabolites have not been elucidated.
