AnotationThe absence or very small proportion of parts of populations with ?climax-growth strategy? faces young Norway spruce stands with problem in mountain regions. The main cause is an improper sorting of seedlings and transplants which was applied in forest nurseries in previous time period (slowlygrowing seedlings were culled). The project is designed to propose a system solution of growing planting stock adapted to mountain localities which means that proportion of plants with ?climax growth strategy? will be increased. Possible combinations of application both vegetative and generative propagation will be evaluated. In nursery, spruce progenies of mountain-population origin will be evaluated in terms of morphological, physiological and anatomical features including investigation of their growth intensity. The different-growth spruces will be exposed to deliberately applied stresses (e.g. air pollution, drought, and frost) and tested for resistance to them. Structural analysis of plant tissues is important for ascertainment of anatomical differences of the investigated progenies (resistant clones). Based on the results, an optimized approach of growing mountain-spruce planting stock will be proposed. The increased share of climax-strategy individuals helps new artificially-regenerated stands to cope with extreme mountain conditions and/ or enables us to substitute fragile forest ecosystems on these sites.
