Influence of provenance transfer on the growth and survival of Picea abies provenances

tom 61 Supplement

Two provenance experiments with Norway spruce in Slovakia were used to reveal trends in the behaviour of provenances after their transfer. Regressions between the average height and survival of provenances and the differences between the geographic and selected climatic characteristics of the place of origin and provenance plots were significant for most of the characteristics tested. Data from the experiment with Polish and Slovak provenances from 1972 indicated that transfer into warmer regions with a longer vegetation period results in improved height growth and survival, with the exception of survival at initial stages. The experiment from 1964 with a broader altitudinal range of provenance plots, but with unadjusted latest measurements at individual plots available, revealed the best height growth of Slovak Norway spruce provenances after their transfer to sites with the mean annual temperature approximately 1°C higher and with the vegetation period 12 days longer than at places of origin. Transfer into lower altitudes, a warmer climate and a longer vegetation period improved survival. In both experiments, transfer to areas with increased rainfall had a negative effect on growth, which is probably associated with the fact that provenances are not able to exploit additional precipitation for the growth in areas with a colder climate and a shorter vegetation period.

Thirty silver fir populations originating from the putative suture zones of the postglacial recolonization (Slovenia, Bosnia and Hercegovina, Ukraine) were studied using a mitochondrial nad5-4 gene marker. The geographical distribution of mtDNA haplotypes in the Ukrainian Carpathians and their northern foothills indicates a very recent meeting of migration streams arriving from the Romanian Carpathians and Central Europe. In the western part of the Balkan Peninsula, two counterparallel migration streams are the most plausible explanation of the pattern observed. The haplotype typical for the Balkan Peninsula predominates along the Adrian coast, whereas the CentralEuropean haplotype is more represented in the inland.
