"Effects of drought stress, stress by increased nitrogen depositions and combined effect of the two stress factors on the growth of Norway spruce (Picea abies /L./ Karst.) were studied in two stands. The drought stress was induced by reduction of atmospheric precipitations by 60%, the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a dose corresponding to 100 kg N.ha-1.year-1. All stress factors under study impacted the height increment of above-ground part, length and colour of needles and the biomass, vertical distribution, functionality and mycorrhizal infection of fine roots. Root system responded to the simulated stresses as early as from the very first year of their effect exhibiting a greater damage than the above-ground part of the plant. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors."@en . "Dendrobiology" . .
