| Hazelnut (Corylus avellana L.) is commonly used as mycorrhizal host for Tuber melanosporum Vitt. (black truffle). Black truffle orchards have been established in and outside its natural distribution area, currently also in Chile. Hazelnut can be propagated rapidly by cuttings, which, however, may not easily form mycorrhizal symbiosis under laboratory conditions. We successfully inoculated hazelnut cuttings with T. melanosporum and studied the effects of culture conditions, plant material and inoculum age on rhizogenesis and mycorrhization. Cuttings from sucker shoots showed the highest rooting rate (88.5%). Perlite and vermiculite as substrate increased root length (9.6 cm ). Treatment with auxin significantly increased root yield (up to 27 roots per... |

| Suillus luteus is the most important wild edible ectomycorrhizal mushroom harvested and exported in Chile. This introduced species forms mycorrhizal symbiosis with Pinus radiata, the most important exotic forest tree. To obtain optimized protocols for the controlled infection of P. radiata trees with this species, it is important to determine the appropriate culture conditions. Therefore, we studied the effect of the geographical origin (three localities from the Maule Region of Chile), culture media (Modified Melin and Norkrans (MMN) and Malt Extract Agar (MEA) 2%), and pH (5.0, 5.8, and 6.5) on the in vitro growth dynamics of S. luteus over 37 days. The results showed significant differences in the growth rate and colony diameter as a consequence of its... |

| Acacia caven (Mol.) Mol. (Leguminosae), generally known as "espino," is one of the most common tree species in the Mediterranean region of Chile. This species grows in nutritionally poor soils with low water availability during the summer, so it is very difficult for new seedlings to become established. To investigate the effects of water restriction and the potential benefit of the application of biosolids (sludge bio-dried to 25% moisture) on the growth of the plant, a completely random, two x three factorial design was carried out in controlled nursery conditions under two irrigation regimes (well-watered plants and controlled water restriction) and three biosolid application rates (0:100, 10:90 and 20:80) in a clay substrate. Physiological evaluations... |

| Nothofagus glauca (Phil.) Krasser es una especie endémica de la zona mesomórfica de Chile que ha estado sujeta a una intensa presión antrópica. Producto de la fuerte reducción de la superficie de sus bosques la especie se encuentra en un delicado estado de conservación y aún no se conocen bien todos los factores que inciden en su propagación vegetativa. Este trabajo estudió la capacidad de arraigamiento de estacas de tallo colectadas de rebrotes de tocón de árboles de más de veinte años de edad de la zona precordillerana de la provincia de Talca. La cosecha se efectuó en enero de 1996 y noviembre de 1997 y, a través de ensayos independientes entre sí, se analizó el efecto del AIB (0; 0.5; y 1.5%) y de la presencia de hojas (con y sin hojas) en el proceso... |
