Starch Degradation Metabolism towards Sucrose Synthesis in Germinating Araucaria araucana Seeds [PDF]

Plant Physiology, 1984
As starch is the main seed reserve material in both species of Araucaria of South America, A. araucana and A. angustifolia, it is important to understand starch breakdown in both embryo and megagametophyte tissues of Araucaria seeds. Sugar analysis by thin layer chromatography indicates that sucrose is the main sugar produced in both tissues.

Starch Characterisation of Araucaria angustifolia and Araucaria araucana Seeds [PDF]

Starch - Stärke, 2007
AbstractAraucaria angustifolia and Araucaria araucana are conifers that cover different areas of South America. Their seeds have been consumed from prehistoric times until today in Brazil, Argentina and Chile. In this work, the starch of Araucaria angustifolia and Araucaria araucana seeds were analysed by light and environmental scanning electron ...

First wild boar density data from Araucaria forest in Patagonian Andes [PDF]

PeerJ
As Sus scrofa is an invasive species in South America, it may have a significant impact on biodiversity. Evaluating this threat requires reliable data, and population density can serve as a critical measure.

Migración Asistida de Araucaria araucana, un estudio de caso en Chile.

Ciencia & Investigación Forestal, 2022
La Araucaria araucana es una especie emblemática de los bosques de Chile y Argentina. En estos últimos años esta especie está siendo sometida a una fuerte presión de selección debida al cambio climático, el que ha predispuesto al daño foliar de la araucaria (DFA), enfermedad que está comprometiendo el 85% de las poblaciones chilenas, lo que ha cambiado

Biotransformation of Araucaria araucana lignans: solid-state fermentation with a naturally occurring Pleurotus ostreatus strain

Rodriguésia, 2022
The effects of a naturally occurring Patagonian strain of the white-rot fungus Pleurotus ostreatus on Araucaria araucana wood lignans was evaluated. Lignans of colonized and non-colonized wood shavings and the activity of fungal ligninolytic enzymes were

Mortierella species from declining Araucaria araucana trees in Patagonia, Argentina [PDF]

Forest Pathology, 2020
AbstractSince 2015, Araucaria araucana, an ecologically and economically important conifer native to Argentina and Chile, has suffered an unusual partial death of the crown throughout almost all of the distribution range in Argentina. No primary pathogen or pest was evident, associated with the phenomenon.

Selected Properties ofAraucaria AngustifoliaandAraucaria AraucanaSeed Protein

International Journal of Food Properties, 2010
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.
