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.

Heterogeneous genetic structure in a natural population of Raulí (Nothofagus nervosa) [PDF]
Ciencia E Investigacion Agraria, 2011 Heterozygote deficiencies in natural populations of outbreeding tree species are common and thought to be due mainly to biparental inbreeding. Inbreeding is believed to be caused by family structure within populations, a product of limited seed dispersal and probably limited pollen dispersal.

Proximal causes of genetic variation between and within populations of rauli (Nothofagus nervosa) [PDF]
Ciencia E Investigacion Agraria, 2009 B. Carrasco. M. Garnier. L. Eaton. R. Guevara, and M. Caru. 2009. Proximal causes of genetic variation between and within populations of rauli (Nothofagus nervosa). Cien. Inv. Agr. 36(2):229-238. Random Amplifi ed Polymorphic DNA (RAPD) markers were used to assess the genetic diversity of 587 individuals, belonging to 22 populations of Nothofagus ...

Microbial Ecology, 2013 Mycorrhizas are mutualistic associations between soil fungi and plant roots which usually improve water and nutrient uptake, influencing plant fitness. Nothofagus nervosa (Raulí) is an ecologically and economically important species of South American temperate forests.

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

Bosque, 2009 Nothofagus nervosa (raulí) es una de las especies nativas chilenas de mayor valor y crecimiento y, por ello, en el último tiempo concita alto interés para el establecimiento de plantaciones. El éxito del establecimiento de plantaciones depende de diversos factores, entre los cuales el manejo en vivero puede ser decisivo.
