Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus) [PDF]
The genus Nothofagus is considered as one of the most interesting plant genera, not only for the living species but also due to the fossil evidence distributed throughout the Southern Hemisphere. Early publications postulated a close relationship between

Micropropagación de Nothofagus pumilio (Poepp. et Endl.) Krasser
Nothofagus pumilio is the most important forest species in South Patagonia. The present work was carried out to determine the suitable cultural conditions for in vitro propagation through shoot culture of saplings and a mature tree. The days after sprouting and the presence of the bud scales were critical for culture initiation.

Insect antifeedant compounds from Nothofagus dombeyi and N. pumilio
A bioassay-guided purification of the extracts of Nothofagus dombeyi and N. pumilio leaves yielded several triterpenes and flavonoids including 2-O-acetylmaslinic acid, 3-O-acetyl 20,24,25-trihydroxydammarane, and 3,20,24,25-tetrahydroxydammarane as new natural products.

Net photosynthetic rate (A) and stomatal conductance (gs) of leaves of Nothofagus pumilio and N. an-tarctica seedlings were measured at different photosynthetic photon flux densities (PPFDs, 20, 150, 250, 500, 750, 1,000, 1,500 and 2,200 μmol/m2/s) and ...

Morphological and architectural features of young Nothofagus pumilio (Poepp. & Endl.) Krasser (Fagaceae) [PDF]
The morphology and architecture of young Nothofagus pumilio plants growing as understorey and in a cleared area were assessed. Length, number of internodes, presence of branches and apex condition were registered for each growth unit (GU) in the sampled plant. GUs were grouped according to branching order and age of the bearing axis. Understorey plants

Analysis of Nothofagus pumilio and Nothofagus antarctica Hybridization Zones in Southern Chile
Interspecific hybridization is documented in various tree species, including the three types of Nothofagus species (N. pumilio, N. antarctica, and N. betuloides) unique to Southern Patagonia. Previous studies found that hybridization results in developmental instability, which is reflected in the increase of leaf fluctuating asymmetry.
