Genetic studies on leaf retention in Quercus robur
1996
Herzog, S. | Krabel, D.
Whereas the autumn abscission of withered leaves in deciduous trees has been the subject of several previous studies, it remains an open question whether it is caused mainly by environmental of by genetic factors. Based on isoenzyme analysis the level of genetic variation and genetic (genotypic as well as allelic) structure in 1 leaf- retaining and 1 leaf-abscising oak stand have been estimated. Both subpopulations were compared on this basis and significant differences have been found for the gene loci under study. Thus, the present study provides some evidence for a genetic basis of the phenomenon of leaf retention.
