MECHANISMS OF DROUGHT TOLERANCE IN MESOXEROPHYTIC OAKS
2003
Blujdea V., Comanescu Pauca M. ,Ionescu M.
At the 70th celebration of the Institute this paper review the overall progress in the knowledge achievement in the area of tree physiology and forest ecophysiology in our country, significantly exemplified by results regarding the mesoxerophytic oaks (Quercus cerris L. si Q. frainetto ten.) and the stand ecophysiology of such ecosystems of great importance for the low altitude area in Romania, under likely climate change impact. It is shown the main research items approached over last 40 years, as well as the main authors involved. As well the results of the research carried out over very recent years are shown (stomatal conductance, photosynthesis, dark respiration, transpiration,mineral nutrition, ecophysiological correlation, etc). The main finding is an outlining of the importance of the tree physiology and forest ecophysiology in the enhancement of the efficacy of managerial act in sustainable management of such ecosystems. Keywords: research, tree physiology, tradition, oaks, drought, gas exchange, water potential
