Influence of some climatic factors on water consumed for evapotranspiration by Nothofagus obliqua (Mirb) Oerst and Nothofagus dombeyi. | Influencia de algunos factores meteorológicos en el consumo de agua por transpiración de Nothofagus obliqua (Mirb) Oerst, y Nothofagus dombeyi (Mirb) Oerst Texto completo

The daily and seasonal variations of water consumption by transpiration and the influence of meteorological parameters on the transpiration intensity were studied in two species of the Fagaceas, Nothofagus obliqua and Notholagus dombeyi.. These species have a wide distribution in Chile and are of- considerable forestry importance. To determine the water consumption of these two species the method proposed by Huber and Ramirez (8) was applied. The experiment was carried out at the meteorological station Isla Tern, of the Austral University of Chile (Valdivia, Chile). The results indicated that increases of solar radiation and air temperature and a decrease of relative humidity lead to an increase in transpiration intensity in both species, which are higher in N. obliqua than in N dombeyi The MatiMUM transpira-don intensities reached were 2 4 1 m 2. in N. obliqua and 1.4 1 in' d" in N dombeyi.. The multiple regression analysis indicated that for both species solar radiation was the most important meteorological factor in regard to transpiration.
