In beech stands (Fagus sylvatica) it is observed, that beech trees with specific trunk morphology, such as forked stems, often occur in groups. At the same time, in naturral regenerated beech stands distinct family structures can be assumed due to a limited pollen and especially seed dispersal. Aim of this work is the investigation of spatial distributions of such family structures. Based on genetic investigations of morphologically differentiated individuals and their natural regeneration in three beech stands in Germany, a possible relation between the variability of the trunk morphology and the genetic variation could be detected. The outcrossing rate estimated by using isoenzyme gene markers was relatively high for all the investigated individuals, as expected. The study of nine enzymatic gene loci GOT-B, IDH-A, MDH-B, MDH-C, PGI-B, PGM-A, LAP-A, 6PGDH-A and MNR-A did not show any clear genetic differentiation between ...
