Raulí (Nothofagus alpina = N. nervosa): The Best Quality Hardwood in Patagonia

2020
Rauli is an iconic species of the temperate sub-Antarctic forests due to its hardwood quality of pinkish tones. Because of its ecological and economic relevance, it is under conservation within national parks and being domesticated for plantation purposes. In this chapter, we present the state of the art of the species in Argentina. General features as

Cell Wall and Lumen Percentages in Relation to Wood Density of Nothofagus Nervosa

IAWA Journal, 1999
Cell wall and lumen percentages were determined for vessels, fibres and rays from 10 trees of Nothofagus nervosa (rauli), and analysed in relation to ring number from the pith, ring width, and density. Increase in density across the juvenile wood was mainly associated with an increase in fibre wall %, which outbalanced a simultaneous increase in vessel

Histological events duringin vitrorooting ofNothofagus nervosa(Fagaceae)

New Zealand Journal of Botany, 2005
Abstract In vitro rooting protocols were previously performed on Nothofagus nervosa to optimise the culture medium and environmental conditions. A qualitative and quantitative tissue differentiation study during adventitious rooting in N. nervosa under different light/dark conditions was carried out to increase knowledge of the rhizogenesis process in ...

Short-distance pollen dispersal for an outcrossed, wind-pollinated southern beech (Nothofagus nervosa (Phil.) Dim. et Mil.)

Tree Genetics & Genomes, 2012
The mating system (outcrossing, selfing, and biparental inbreeding) and the extent of pollen flow are two of the most important genetic features that determine the genetic structure of plant populations, and both are crucial for the design of conservation strategies.

Annual and geographic variation in seed traits of Argentinean populations of southern beech Nothofagus nervosa (Phil.) Dim. et Mil.

Forest Ecology and Management, 1999
Abstract Nothofagus nervosa (=N. alpina) is one of the most important native forest tree species of Argentina, with a very small natural distribution area, fast growth and a high wood quality. Its overexploitation in the past seriously affected some populations and made others disappear, making it necessary to implement conservation policies and ...

Chloroplast DNA markers reveal a geographical divide across Argentinean southern beech Nothofagus nervosa (Phil.) Dim. et Mil. distribution area

Theoretical and Applied Genetics, 1998
Nothofagus nervosa is one of the most important species of the temperate forests of southern South America. On the eastern slope of the Andes Mountains (Argentina) it has a very small and narrow natural distribution area which follows the valleys of the numerous west-east lake basins.

Growth-unit structure in trees: effects of branch category and position on Nothofagus nervosa, N. obliqua and their hybrids (Nothofagaceae)

Trees, 2010
In plants with rhythmic growth, a branch segment extended in one event is known as growth unit (GU). GU structure, resulting from the resources allocated to stem length, volume and mass, and to leaf area and mass, is relevant for understanding branch functioning in the context of plant development. This study compares GU structure between main branches

Morphological description and pollen viability of Nothofagus nervosa (Nothofagaceae)

2017
Entender la biología del polen es necesario para mejorar la reproducción de las especies vegetales y para la implementación exitosa de programas de mejoramiento genético y conservación. Con el fin de contar con información sobre las características morfológicas y de viabilidad del polen en Nothofagus nervosa, se colectó flores masculinas de árboles ...

Growth of a plantation of Nothofagus nervosa in Valdivia in a 20-year period

2007
Este trabajo tuvo como objetivo analizar el crecimiento de una plantación ex situ (39º45’ S, 73º09’07” O, 125 m s.n.m.) de Nothofagus nervosa de 20 años y determinar las causas de su variación espacial. En tres sitios (1: área de mayor crecimiento, DMC = 16,5 cm, altura dominante 14 m; 3: área de menor crecimiento, DMC = 8,1 cm, altura dominante 8 m; y
