Beech, fir and spruce regeneration response to high irradiance after ice storm natural disturbance

Popis výsledku v původním jazyce

Young beech, silver fir and Norway spruce response to high irradiance after the severe ice storm in 2014 in the Slovenian mixed forest stands was measured at four locations and compared with response of same species on managed sites, that were gradually adapted to the same light intensities. Nitrogen content (Ntot), Leaf mass per area (LMA), and Quantum yield (Φ) were measured in three categories of different light intensities under closed canopy with indirect site factor (ISF)&lt;15%) at the forest edge (15%&lt;ISF&lt;25%) and in the open (ISF&gt;25%) during two years (2015 and 2016) after the disturbance event. Nitrogen content of all three species was within optimal threshold values, highest in the open and lowest under canopy conditions on every plot. Rapid exposure to increased light levels affected most directly fir in the category of forest edge and under open canopies. Contrary to fir responded beech in a favourable way, while no differences in response were evident in spruce. Assimilation efficiency, where both fir and beech were equal shifted towards the shade in both years.
