An ecophysiographic approach for Araucaria araucana regeneration management [PDF]

Ciencia e investigación agraria, 2012
Chilean temperate forests are dominated by Nothofagus and Araucaria araucana species. Despite A. araucana not being at imminent risk of extinction, its cultural value and the associated environmental services and landscape goods have an important role for the conservation of this native forest. In some areas, the future conservation of A. araucana is a

Poblaciones de araucaria enana (Araucaria araucana) en la Cordillera de Nahuelbuta, Chile [PDF]

Bosque (Valdivia), 2008
Araucaria araucana (araucaria o pehuen) desarrolla normalmente en su habitat natural un crecimiento arboreo con altura > 20 m. Sin embargo, en 1984, en la cima de la Cordillera de Nahuelbuta se encontraron dos poblaciones enanas. En este trabajo se caracterizo la estructura, composicion y edades de ambas poblaciones de A.

Selected Properties ofAraucaria AngustifoliaandAraucaria AraucanaSeed Protein [PDF]

International Journal of Food Properties, 2011
Araucaria angustifolia and Araucaria araucana are coniferous trees with large and nutritious seeds. The structure and nutritional properties of the proteins of these seeds were studied. About 70% of the proteins of the gametophyte were soluble in distilled water, although their solubility decreased drastically in raw seed flour.
