Some research topics in the field of genetic variation, genetic resources, provenances, genetic<br />
monitoring, genetic differentiation and diseases of beech, which have been conducted in the past five<br />
years or are still un<strong>de</strong>r investigation (BLE 2009) may be mentioned below:<br />
Three studies are un<strong>de</strong>r way to analyse, assess and correlate the resistance or tolerance to drought<br />
in populations of beech. This is particularly of interest in the eastern part of its distribution, where<br />
the rainfall is at its lower limit for beech. Additional studies of wood anatomy and chlorophyll-afluorescence<br />
are also integrated into these studies. Some studies are <strong>de</strong>aling with the genetic structure<br />
in regenerated populations, the influence of thinning on the genetic structure, and the variation in<br />
stands. Genetic monitoring occupies a large part of research, in particular the long-term monitoring<br />
in cooperation with the environmental monitoring of the Level II plots, which have been established<br />
during an EU-wi<strong>de</strong> project. Distinction between seed lots by using stable isotopes or between<br />
Fagus sylvatica and F. orientalis by nuclear marker has been successful. In an ol<strong>de</strong>r provenance trial<br />
it could be shown that economic value, e. g. straight stem form and fine branching, is influenced<br />
by the provenance. Over recent years the <strong>COST</strong> <strong>Action</strong> E<strong>52</strong> is focussing on a joint evaluation of<br />
the international beech provenance trials. Furthermore the complex disease of beech occurring in<br />
western parts of Germany is being investigated more intensively.<br />
