Canadian Journal of Forest Research, 2011 In the Andes of Chile, two valuable Nothofagus tree species coexist (Nothofagus dombeyi (Mirb.) Oerst. and Nothofagus nervosa (Phil.) Krasser). They could provide an opportunity for mixed plantations because of their ecological differences. In a mixed plantation with a checkerboard design on a good site where the two species naturally coexist, we ...

Successive media to improve the in vitro rhizogenesis of Nothofagus nervosa (Phil.) Dim. et Mil.
New Forests, 2003 In vitro rooting constitutes a difficult step during the micropropagation process of forest species. The successive media culture technique represents one way to overcome this barrier and includes modifying physical (e.g. photoperiod) and chemical (e.g. flavonoids) factors during the rooting phases.

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 ...

Agrobacterium rhizogenes vs auxinic induction for in vitro rhizogenesis of Prosopis chilensis and Nothofagus alpina [PDF]
, 2003 The induction and improvement of in vitro rhizogenesis of microshoots of Prosopis chilensis (Mol.) Stuntz and Nothofagus alpina (Poep. et Endl. Oerst.) were compared using Agrobacterium rhizogenes (Ar) versus indole-3-butyric acid (IBA) in the culture ...
