Abstract :

Frost is one of the main limitations to commercial eucalypt plantation in Southern Brazil. The trial aimed to select eucalypt species with a favourable growth rate and frost resistance. Results confirm E. dunnii and E. viminalis as species recommended for commercial plantation in the region. E. deanei and E. macarthurii are also considered to have potential, but they were not sufficiently test ...

Abstract :

Forest ecosystems have already now heavily responded to the man-made changes in environmental conditions that have occurred since the middle of the 19th century. All investigated species showed a long term increases of radial growth, which means there is a general increase in forest ecosystem productivity

Abstract :

Geographic transfers over long distances are accompanied by changes in climatic changes. As climatic warming is expected during the coming decades, series of transfers to warmer climate regimes are most relevant. The results show that both Picea abies and Pinus sylvestris are able to adapt to climatic warming. The changes are mainly physiological, but some genetical screening is plausible. At ...

Abstract :

In Brazil researches on silviculture started at the beginning of 20th century, the initial technical and scientific studies concerning Eucalypts in Brazil started in 1904. From 1960 the research on Eucapypts had consolidated and expended, and in 1964 the Forestry Institute of Sao Paulo established an intensive programme of superior trees selection. Nowadays Brazil has very valuable genetic pro ...

Abstract :

Through the increasing amounts of carbon they immobilize, forest ecosystems play an important role in attenuating the man-made increase of atmospheric carbon dioxide. If carbon dioxide emission remain high in the future decades, forest ecosystems will not be able to avoid a considerable, and long-term increase of atmospheric carbon dioxide concentration

Abstract :

Examination of this preliminary data reveals that dimensional parameters height and diameter, and the physiological parameters predawn water potential and stomatal conductance. Net photosynthesis and transpiration are less useful because of greater variation within groups and high labour requirements. Ys is apparently unresponsive to drought and is not likely to be useful as a determinant of d ...
