Branch whorls of juvenile Araucaria araucana (Molina) Koch: are they formed annually? Los verticilos de juveniles de Araucaria araucana (Molina) Koch: ¿son formados anualmente?

Revista Chilena de Historia Natural, 2000
The growth of Araucaria araucana, like that of many other conifers, is characterised by the production of a monopodial stem with branch whorls. However, the periodicity of whorl formation in this species has not been subjected to systematic study.

Ontogenetic variation in light interception, self-shading and biomass distribution of seedlings of the conifer Araucaria araucana (Molina) K. Koch Variación ontogenética en la intercepción lumínica, autosombramiento y distribución de biomasa en plántulas de la conífera Araucaria araucana (Molina) K. Koch

Revista Chilena de Historia Natural, 2006
One of the factors thought to contribute to ontogenetic declines in plant growth rates is diminishing light interception efficiency, as a result of the difficulties of avoiding self-shading among a growing number of leaves, and by stems.

Avifauna de los bosques templados de Araucaria araucana del sur de Chile

Ecología Austral, 2010
Los estudios sobre el ensamble de aves de los bosques templados de Araucaria araucana son escasos. Como resultado, no se conocen ni los cambios estacionales del ensamble, ni el efecto de la profundidad de la nieve invernal sobre la diversidad, ni los ...

Secondary metabolites from Araucaria araucana (Molina) K.Koch leaves

The first phytochemical analysis concerning the non-volatile secondary components of one European specimen of Araucaria araucana (Molina) K.Koch led to the identification of five compounds: sandaracopimaric acid (1), ladanein (2), shikimic acid (3), 4-O-coumaroyl-quinic acid (4) and 5-O-coumaroyl-quinic acid (5).
