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.

Role of polyamines during in vitro rhizogenesis of Nothofagus nervosa using successive culture media [PDF]
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 ...

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 ...

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.

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.

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
