Název v původním jazyce

Decline of Norway spruce in the Krkonoše Mts.

Popis výsledku v původním jazyce

The work summarizes results from the analyses of Norway spruce (Picea abies /L./ Karst.) stands managed by Forest Administration Horní Maršov, The Krkonoše National Park (KRNAP), that are affected by decline and by yellowing of the assimilatory apparatus. Forest stands included in the analyses were aged 10-80 years and originated from both artificial and natural regeneration. Analyses of root systems were combined with analyses of soil chemical properties and assimilatory organs, weather behaviour and emissions. The analyses showed that affected trees have a small and malformed anchoring root system with a lower number of horizontal roots, a lower number of fine roots with lower vitality (high proportion of dead fine roots), which penetrate only through the uppermost humus horizons. Root systems of affected trees are infested by honey fungus (Armillaria sp.), which colonizes anchor roots. Root or bole rots were not detected so far.
