Opis:
Modern forest selection programs concern natural and protected populations of trees characterized by a great genetic variability and also production stands frequently deformed by human activity. In the latter, artificial regeneration is prevailing. Forest nurseries working in the organizational structures of State Forests can guarantee the proper provenance (genotype)of seeds and the quality of seedlings obtained from them. The condition, however, is a close uniformity in the conservation of forest gene resources, and selection breeding of forest trees. The success of the program depends also on the development of modern infrastructure for forest nurseries and applied technologies. The latter task was the field of activity of Professor Bolesław Suszka, Ph.D., and his many-year research and organizational and didactic activity in Poland and abroad. The methods in long-term storage and their pretreatment in case of dormant seeds, developed by Professor Suszka, created the theoretical and practical basis for the conservation of forest gene resources not only in Poland.

random amplified polymorphic DNA
Opis:
A sample of Betula nana from the Linie reserve near Dąbrowa Chełmińska, have been fingerprinted using random amplified polymorphic DNA (RAPD). The high level of genetic variation was detected. All individuals had unique genotypes, supporting the generally high resolving power of RAPD’s. For the conservation strategy, information about the distribution of the genetic variation within and among populations plays very important role. Thus, extensive study in other populations of dwarf birch is needed.

Opis:
The forests of the Silesian Beskid Mts have a specific composition with a marked dominance of Norway spruce. Although spruce stands are seriously threatened, some of them, such as those of Istebna race, show excellent genetic value. The work stresses the need for the conversion of spruce stands in the Silesian Beskid range on the basis of population genetics and describes the principles of such conversion.
