    Opis:
    The paper summarises the results of climatological studies concerning the area of the Carpathian Regional Gene Bank station located in the Wisła Forest District. The work provides raw meteorological data, daily, monthly, seasonal and annual records, and various indices such as the pluvial-thermal index, biometeorological index, Sielianinow’s index and de Martonne’s index. In addition, the detailed profiles of thermal, humidity and rainfall conditions are presented against a background of the general synoptic situation.

    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.

    Opis:
    In the Forest Gene Bank cold stores, both long-term and strategic gene resources are stored to be used during periods of poor seed production. Beech seeds of the following harvests were evaluated: 1995, 1998 and 2000. Quality of seeds was determined with different methods from the date of reception to FGB through preparation for long-term storage, storage in cold stores and the presowing treatment. The usefulness of staining tests for rapid evaluation of beech seed viability is not sufficiently sure. The floating test in water significantly improves the level of seed purity. The current method of seed drying does not remain without influence upon beech seeds and causes a slight decrease of viability. Next to beech seed lots of rapidly declining quality in the FGB are stored seed lots whose viability does not decrease during identical technological processes. Seed lots of low initial viability should be eliminated.

    Opis:
    The work outlines the directions in the past and present research into the variability of Norway spruce in Poland, and presents the results of provenance experiments concerning the genetic and breeding value of provenances tested in the Polish range of spruce distribution. The Istebna race proved to have a good value, however, so far only the progeny of single stands have been tested. It is thus necessary to determine the range of distribution for this race. The altitude of the location of mother stands significantly correlates with the genetic and breeding value of their progeny cultivated at different altitudes. This suggests that the altitude and exposure of plantations to be established in mountain forest belts should be specified for individual provenances (altitudinal zoning). New inventory provenance tests should be run under varied site conditions to assess both the genetic value and plasticity range of the provenances. In view of the biotic and abiotic threats facing spruce, there is a need to work out detailed programmes designed to preserve its genetic resources in gene banks and in vivo archives.

    Opis:
    The paper describes the measures adopted by the Czech State Forests for the conservation and reproduction of the Norway spruce gene pool in the Moravian-Silesian Beskid Mts. In addition to the assurance of natural regeneration in genetically valuable stands and the use of high-quality autochthonous stands as seed sources for artificial regeneration, the measures include selection of plus-trees, establishment of seed orchards, seed stands and clone archives, and identification of gene pools. Seeds of the most valuable regional populations are deposited in a seed bank.
