Great Similarity

The comparison of the genetic stucture of the population of Scots pine from Szczeliniec Wielki Mt. with the population of its progeny and three other populations from the same geographic region shows great similarity of both populations as far as the frequencies of genes and genotypes are concerned. Also other genetic parameters, such as heterozygosity, genotypic polymorphism indices and a number of alleles per locus were in both populations very similar. It seems that our data proved that the provenance trial experiments reflect rather closely the genetic structure of maternal populations. The fact that the population from Szczeliniec Wielki and its "replica" are genetically most similar to the geographically closest population from Bystrzyca Kłodzka leads to the conclusion, that these populations are of common origin. Though the relic character of the population from Szczeliniec can not be excluded. The morphological distinctness of the population from Szczeliniec is caused by a modifying influence of environmental conditions.

Biometric characters of seeds and wings served to describe interprovenance differentiation of Scots pine in Europe. Grouping analysis was applied, Mahalanobis distances were calculated as well as Hotellings T<sup>2</sup> statistics were applied. The similarity of East European and Finnish provenances was conspicuous. The provenance from Scotland proved to be similar to provenances originating from the region of Scandinavia. On the other hand, two southern provenances 54(Rychtal, Poland) and 55(Luboml, Ukraine), were also found similar to provenances originating from the region of Scandinavia (western Norway). The obtained pattern of reciprocal relations may indicate pathways of Scots pine migration in the postglacial period or may be a result of adaptation to certain similar environmental conditions. No relations were detected between size of seeds and geographic origin of provenances.

Positive Effect

Evaluation of the   progeny test of plus trees of Scots pine - a necessary condition for determining the prospects the use of improved seeds in different environmental conditions. The paper presents the results of the study of the progeny test of groups of clones of plus trees of Scots pine selected according to certain characteristics in Northern Steppe and South Forest-Steppe of Ukraine. Analysis of results showed: a significant improvement in the growth rates of the all testing progenies of seed orchard in the better climatic and soil conditions of South Forest-Steppe between the ages of 3 and 10 years. At the same time 4 out of 5 studied progenies worsened their growth indicators relative to local control at the age of 3 to 26 years in less optimal climatic and soil conditions of Northern Steppe. The leader in the steppe conditions was the progeny of a fraction of three clones, which had the highest seed productivity. The selection of the fastest growing clones and the rejection of the slowest growing ones had a positive effect on the growth of progenies of seed orchards at both test points.

The Impact

Climate change influences the ecological environment and affects the recruitment of plants, in addition to population dynamics, including Scots pine regeneration processes. Therefore, the impact of cover-dominant species extracts on the germination of pine seeds and morpho-physiological traits of seedling under different environmental conditions was evaluated. Increasing temperature reinforces the plant-donor allelochemical effect, reduces Scots pine seed germination, and inhibits seedling morpho-physiological parameters. Conditions unfavourable for the seed germination rate were observed in response to the effect of aqueous extracts of 2-year-old Vaccinium vitis-ideae and 1-year-old Calluna vulgaris under changing environmental conditions. The lowest radicle length and hypocotyl growth were observed in response to the effect of 1-year-old C. vulgaris and 2-year-old Rumex acetosella under increasing temperature (+4 °C) conditions. The chlorophyll a + b concentration in control seedlings strongly decreased from 0.76 to 0.66 mg g−1 (due to current environmental and changing environmental conditions). These factors may reduce the resistance of Scots pine to the effects of dominant species and affect the migration of Scots pine habitats to more favourable environmental conditions.
