    Opis:
    The paper presents the results of research concerning the genetic variation in the growth traits and phenotypic plasticity of Norway spruce populations from the Silesian Beskid Mts and compares them with those of twenty Polish spruce provenances planted on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. The Silesian Beskid spruce is represented by six populations from the Wisła and Ujsoły Forest Districts. The variation in the growth traits of all populations discussed (data from all plots) is 6.009 standard deviation units. At population level this variation is also comparatively high and ranges between 4.674 for the Kartuzy spruce and 2.1920 for the Rycerka Zwardoń spruce. The Silesian Beskid spruce populations are not homogeneous but they belong to the populations with a high or moderate growth rate. The Istebna Bukowiec spruce performed the best on most plots. Only on Finnish and Canadian plots the growth traits of this population were below the average.

    Opis:
    The paper presents the results of research on the genetic variability in the growth characteristics and plasticity of Polish provenances of Norway spruce, tested on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. Special consideration was devoted to the plots in Poland, especially in Knyszyn. The variability in the growth and quality characteristics of the provenances, found at experiment level, is high (within 6.099 standard deviation units). At provenance level, it ranges between 4.674 for Kartuzy and 2.192 for Rycerka Zwardoń. This indicates that the performance of the provenances depends much on environmental conditions. Although no provenance can be considered adaptable to any conditions thatmay occur in the cultivation of spruce, the Istebna Bukowiec and Zwierzyniec Lubelski provenances, having a very high breeding value and high plasticity, may be recommended for a wider use in reforestation.

    Opis:
    The study investigates the intra-population variability of the growth and quality traits of Norway spruce populations from Bliżyn and Zwierzyniec Lubelski. The two populations are included in the IUFRO 1972 experiment and exhibit a high growth dynamics and a narrow crown form. The research was carried out on the experimental plot established in 1996 in Chrosno (Kutno Forest District) using 8228 two-year-old seedlings planted in a single-tree plot design at a spacing of 1.5 × 1.5 m. The seedlings represent 191 open-pollinated families, among them 93 families of Norway spruce from the Bliżyn region and 98 families from the Zwierzyniec Lubelski region. The height, height increment and DBH of trees were measured periodically, and some quality traits were assessed. The last results come from the measurements done on the trees aged 10 years. It was found that the differences between the two populations of Norway spruce are statistically nonsignificant but both of them show wide within-population variability. This suggests that they have the potential to flexibly respond to future changes in the growth conditions or to seed transfer to other seed zones. Survival in the environmental conditions of the experiment was independent of family.
