Results of provenance research of Norway spruce in thecontext of ongoing bark beetle calamity

Original language description

There are presented evaluation results of two research plots (Mnichov and Červená Voda) of the international provenance trial with Norway spruce 1972/76–77 at the age of 46 years. Both plots are situated in north of Moravia (Czech Republic) in area infested by extreme bark beetle calamity. On both plots, the identical 64 provenances originated from the Czech Republic, Germany, Austria, Poland, Slovakia, Belarus and Bulgaria are tested. Provenances from four geographical Norway spruce regions according to Rubner (1932) are represented. Dendrometric data (tree height, DBH) were measured and morphological characteristics (stem form, stem damage, defoliation, and health state) were evaluated. Stem volume and growing stock were calculated from measured data. The measurement was performed in 2018 after 3-years long period of extreme summer drought. The results show the highest volume production in both research plots for provenances from Germany, namely 41 Hainsbach (Červená Voda) and 39 Bütterbächel (Mnichov). As for wider geographical provenances origin, two homogeneous groups were clustered (1) Alpine, Rhodopean and Russian-Scandinavian, and (2) Hercynian-Carpathian. The second one represented the best growing provenances, so spruces with this origin may be theoretically recommended for using in regional silviculture in upcoming climatic conditions.
