Can seedlings of Norway spruce ( L. H. Karst.) populations withstand changed climate conditions?

A manipulative experiment with two different water regimes was established to identify the variability of physiological responses to environmental changes in 5-year-old Norway spruce provenances in the Western Carpathians. While variations in the growth responses were detected only between treatments, photosynthetic and biochemical parameters were also differently influenced among provenances. Following drought treatment, an obvious shrinkage of tree stems was observed.

Dynamics of internal isoprenoid metabolites in young Picea abies (Norway spruce) shoots during drought stress conditions in springtime.

Currently, large areas of Picea abies (Norway spruce) stands in Europe are increasingly affected by drought and heat waves. Moreover, early spring drought has occurred with much higher frequency. Our work focuses on physiological changes induced by drought in four-year-old spruce seedlings during shoot elongation.
