Regeneration mode affects spatial genetic structure of Nothofagus dombeyi forests

Molecular Ecology, 2005
AbstractDisturbance may generate population bottlenecks by reducing population size and the number of founders establishing a new colony. We tested the hypothesis that the scale of disturbance affects the levels of genetic diversity and the spatial distribution of genotypes in naturally regenerating stands of Nothofagus dombeyi, an evergreen angiosperm

Diameter growth models for Nothofagus dombeyi

2001
Models of diameter growth for Nothofagus dombeyi were developed and the selected model used for this study was non-linear and known as Bertalanffy-Richards. It was fitted from three main data sources: permanent plots (with only two measurements each), stem analysis and tree cores.

Die Markfleckigkeit des Coigue-Holzes [Nothofagus dombeyi (Mirb.) Oerst.]

Holz als Roh- und Werkstoff, 1969
Der Coigue [Nothofagus dombeyi (Mirb.) Oerst.] ist die nach Bestandesflache, Stammzahl und Holzvorrat bedeutendste Laubbaumart des chilenischen Naturwaldes. Seine kennzeichnenden Holzeigenschaften werden beschrieben. Unter den Fehlern des Coigueholzes kommt der Markfleckigkeit besonderes Gewicht zu, da sie artspezifisch ist und in fast allen ...

Changes in free amino acid content and frost resistance in Nothofagus dombeyi leaves

Phytochemistry, 1986
Abstract The annual course of frost resistance and free proline content was studied in leaves at different stages of development of a woody species (Nothofagus dombeyi) from Southern Chile. The freezing resistance reached a minimum in late spring or summer and a maximum in the autumn-winter period.

Kiln Drying of coigüe wood (Nothofagus dombeyi)

1992
Se aplicó un programa de secado artificial para secar madera de coigüe (Nothofagus dombeyi) de 1" de espesor, pretratada mediante inmersión en agua a 70° C durante 48 horas. Se planteó como objetivo específico aplicar un programa de secado en base a contenido de humedad y evaluar en forma técnica la calidad del secado de la madera tratada. El ensayo se

Lipid composition of chloroplasts from cold-acclimated and non-acclimated Nothofagus dombeyi

Phytochemistry, 1991
Abstract Lipid composition of thylakoid and envelope fractions of osmotically ruptured chloroplasts isolated from cold-acclimated and non-acclimated leaves of the Chilean evergreen Nothofagus dombeyi growing at lowland (thermic favourable conditions) and highland (thermic unfavourable conditions) was determined.

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.

Regeneration dynamics of Austrocedrus chilensis and Nothofagus dombeyi in declining forests

2018
The Austrocedrus chilensis forests in Argentina experience a process of decline and mortality with important impacts on the structure and population dynamics. Although its study has received significant attention over time, knowledge related to the growth of the regeneration and its response to the gradual changes in the canopy over time ...

Diametric growth model of Nothofagus alpina and its relationship with that of Nothofagus obliqua and Nothofagus dombeyi in the natural forest from Patagonia of Argentina

2018
Los modelos de crecimiento arbóreo contribuyen a describir la estructura y el funcionamiento del bosque, predecir la producción de madera, implementar alternativas silvícolas y evaluar la dimensión económica forestal. Nothofagus alpina, Nothofagus obliqua y Nothofagus dombeyi (Nothofagaceae) conforman bosques naturales en el noroeste de la Patagonia ...
