Abstract
The management of Scots pine forests in the Northeastern German lowlan d distinguishes two morphological types, the so called A-type with a n arrow crown and finer branches, which can perform timber of a high qua lity, and the so called B-type with a wide crown and thicker branches. In the present work first results of a genetic analysis with isozyme markers of these two morphological types selected from three provenanc es are shown. We found a higher level of heterozygosity based on a hig her number of rare alleles in the A-type group compared with the B-typ e group. The silvicultural thinning practice which favours the A-type trees by removing the B-type trees is discussed with regard to the gen etic aspect.
