Ten enzyne Systems representing 15 allozyme loci were assayed in seeds
(megagametophyte [1N] and embryo [2N] tissues) from 3 Douglas-fir (Pseudotsuga …

As a result of widespread deforestation and overexploitation, many tree species have
become the focus of growing conservation concern. At the Flemish scale, recent protection …

Due to its high productivity and good ecological and silvicultural characteristics, Douglas-fir
plays a special role among foreign species in Germany. A decisive factor in successful …

Tree species, like other biological organisms exhibit a wide degree of phenotypic variation.
The variation results from their genetic constitution, the environment in which they grow, as …

The genetic structure in Danish indigenous and introduced provenances of beech (Fagus
sylvatica L.) is described. Ten stands are analysed based on variation revealed by seven …

Allozyme markers (11 loci, 32 alleles) have been used to estimate the genetic diversity
within the unique surviving population of the relic species Abies nebrodensis. Results were …

Adult individuals and seeds of two mixed stands of coastal and interior Douglas-fir
(Pseudotsuga menziesii (Mirb.) Franco) were analysed for genetic differentiation between …

For long-lived plants that have to cope with high temporal and spatial environmental
heterogeneity, genetic diversity is of prime importance for species persistence. Detrimental …

This report provides a survey of the results of genetic investigations using isoenzymes as
genetic markers on the impact of nature orientated forest management on the genetic …
