Role of polyamines during in vitro rhizogenesis of Nothofagus nervosa using successive culture media
New Forests, 2007 An in vitro rooting protocol for producing Nothofagus nervosa microplants using successive steps during tissue culture is reported. Qualitative and quantitative changes in putrescine, spermidine, and spermine tissue contents, during the rooting process and their correlation with other biochemical markers and morphological changes, provided the ...

Cell Wall and Lumen Percentages in Relation to Wood Density of Nothofagus Nervosa
IAWA Journal, 1999Cell 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

Raulí (Nothofagus alpina = N. nervosa): The Best Quality Hardwood in Patagonia
2020Rauli 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

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

Efectos de la poda de tallo y fertilización de liberación controlada en vivero sobre el comportamiento de plántulas de Nothofagus nervosa en terreno [PDF]
Bosque, 2009 Nothofagus nervosa (rauli) es una de las especies nativas chilenas de mayor valor y crecimiento y, por ello, en el ultimo tiempo concita alto interes para el establecimiento de plantaciones. El exito del establecimiento de plantaciones depende de diversos factores, entre los cuales el manejo en vivero puede ser decisivo.

Fungal Ecology, 2015 Abstract Due to its overexploitation during the past century, Nothofagus nervosa is currently included in conservation and domestication programs, in which ectomycorrhizas play an important role. We aimed to describe the abundance and diversity of ectomycorrhizal fungi (EcMF) in both domesticated and naturally established N.

Cocultivo in vitro de callos de Nothofagus nervosa con el hongo xilófago Postia pelliculosa [PDF]
Bosque, 2007 Se describe el cocultivo in vitro de callos de varios genotipos de Nothofagus nervosa (rauli), con una cepa del hongo xilofago Postia pelliculosa. Los callos se obtuvieron de hojas y tallos provenientes de cultivos in vitro. Para la induccion de la callogenesis, se utilizo el medio de cultivo Broadleaved Tree Medium (BTM) suplementado con 2,4 ...

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
