The presence of antimicrobials in root, hypocotyl and cotyledon homogenates of Norway spruce was studied using in vitro assays with soil-borne pathogens. For the studies presented here Norway spruce (<em>Picea abies</em> (L.) Karst.) as a typical host and forest tree and <em>Pythium</em> as a typical soil-bome pathogen were used. The highly virulent species <em>Pythium ultimum</em> and the less virulent species <em>Pythium irregulare</em> were chosen for all experiments. They are both the causal agents of damping-off disease, which can affect plants at a very early stage. The strongest antimicrobial effect was observed using medium prepared from older seedlings and containing extracts from cotyledons. The influence of various treatments on antimicrobials accumulation in spruce extracts was also tested. Seed coat shedding was observed to affect mortality of <em>Picea abies</em> seedlings infected by <em>Pythium</em>. Seedlings which had shed their seed coats were more resistant to <em>Pythium</em> attack. This phenomenon could be correlated with antimicrobial production in well developed cotyledons.

Simulation Results

AbstractThe FORKOME model used in the article contains elements of forest and ecological approaches and was specially developed for the conditions of the Gorgans. The modeling was performed based on the single simulation results and statistically averaged forecast of 200 simulations (“Monte Carlo”) in order to show the tendency of changes and their correspondence with single simulations. The forecast of the forest dynamics was conducted at the 100th anniversary period with “control” and “warm-dry” scenarios. It has been revealed that the rapid decrease in biomass in the first decade was caused by Norway spruce decline. It was revealed that in the control scenario, the most active biomass growth during the 100th year forecast was shown by Silver fir (Abies alba Mill.) and beech (Fagus sylvatica L.). The fir reacted relatively sensitively to the warming and decrease in rainfall. The relationships between tree species and the influence of biomass of Norway spruce tree on the biomass of the whole forest tree stand were analyzed.
