In vitro Propagation of Nothofagus obliqua (Fagaceae).

Australian Journal of Botany, 1995
Suitable culture conditions were investigated for in vitro propagation through shoot culture of seedlings and the acclimatization of the rooted plantlets of Nothofagus obliqua. Explant size and leaf expansion were critical for culture initiation. A medium with a low salt concentration and the addition of L-glutamine, as broadleaved tree medium, was ...

The First Network of Tree-Ring Chronologies for Co-Occurring Nothofagus nervosa and Nothofagus obliqua along a Precipitation Gradient in Patagonia, Argentina

Tree-Ring Research, 2022
We present the first network of tree-ring chronologies for co-occurring Nothofagus nervosa and Nothofagus obliqua in Argentina. Using standard dendrochronological techniques, we developed seven tree-ring width chronologies for each species, encompassing their E-W distribution along a precipitation gradient.

Genecological differentiation in Nothofagus obliqua (Mirb.) oerst. in Chile

Forest Ecology and Management, 1979
Abstract The genecological differentiation of Roble (Nothofagus obliqua (mirb.) Oerst.), a common and economically important forest tree in central Chile and the adjacent region of Argentina, was analyzed by considering variation in two morphological traits and a single physiological characteristic. Variation in seed weight (associated with seed size)

Preliminary results in cold storage with seeds of coigüe (Nothofagus dombeyi), roble (Nothofagus obliqua) and rauli (Nothofagus alpina)

1996
Many species have two or more very low seed production year. With the purpose of continuosly covering the needs of the nurseries with viable seeds during theses low productions periods, storage essays with some species were initiated. Results obtained with seeds of Nothofagus dombeyi, N. obliqua and N.

Proposition of growth zones for roble (Nothofagus obliqua) and raulí (Nothofagus alpina) second growth forests

1993
El presente estudio caracterizó y evaluó los crecimientos de renovales de roble (Nothofagus obliqua) y raulí (Nothofagus alpina) en 40 localidades, entre los paralelos 35° y 41° latitud sur. Se agruparon los renovales para cada especie en 4 zonas de crecimiento.

Age and natural durability of second growth forest of Nothofagus obliqua

2000
Se determinó la durabilidad natural de 9 árboles de roble con edades entre 45 y 70 años a distintas alturas del fuste y distintas localizaciones en diámetro, mediante un proceso acelerado, utilizando como agente de deterioro el hongo Gloeophyllum trabeum en un período de cuatro meses.

Application of moisted hydrogel on roots of Nothofagus obliqua (MIRB.) OERST. and Nothofagus dombeyi (MIRB.) OERST. before transplant

1999
El trabajo con especies forestales nativas en el país se ha centrado, principalmente, al estudio de comunidades boscosas existentes y a su manejo. La posibilidad de utilizar diversas especies de dichas comunidades en forma de bosque artificial ha cobrado relevancia en los últimos años. El género Nothofagus es el más estudiado.

Evaluación de la defoliación producida por insectos en Nothofagus obliqua (roble)

Se presenta una pauta de evaluación visual diseñada para el monitoreo de la defoliación producida por insectos en árboles de roble. La evaluación se realiza en lo que se denomina "Copa Evaluable", estimando un porcentaje de defoliación que se clasifica en una de cuatro categorías.

Preliminary site index curves for pure and mixed forests of Nothofagus alpina and Nothofagus obliqua in Patagonia Argentina

2017
The growth of the dominant height of the stand and the IS is assumed to express the effects of all relevant site factors on the growth. The objective was to develop a function which could express the dominant growth pattern in height within the range of ages and site qualities in mixed N. alpina and N. obliqua (Neuquén, Argentina).
