| Description
| - Roots are stressed rather often under natural conditions, eg when considering sloping terrain, layers of fluvial deposits, huge layers of melting snow, load of heavy forest machinery during logging and hauling operations, recreation activity of people, high density of deer or cattle, etc. We focused our experiments on Norway spruce (Picea abies [L.] Karst.) seedlings grown in containers with glass walls under the permanent load of 5.1 kPa during the whole growing season. The applied pressure affected roots both directly and indirectly due to the occurrence of hypoxia. Root growth ceased under such conditions. Growth dynamics and capability to occupy available soil were also changed. For example, the total root area of experimental plants decreased to 52% but root area index (RAI) was higher by 33% when compared to the control. This indicates that pressure applied to soil surface caused the development of only smaller root systems but also more compacted into smaller volumes of soil. Mean longitudinal

- Tlak na kořeny se vyskytuje poměrně často ať již na svažitých terénech, pod nánosy naplavenin, při jarním tání vysoké sněhové pokrývky nebo činností člověka při pojezdu těžkých mechanizmů v lesních porostech, při rekreačních aktivitách, při vysokých stavech zvěře a pastvě hospodářských zvířat v lesích aj. Byly provedeny experimenty se sazenicemi smrku ztepilého (Picea abies [L.] Karst.), které byly pěstovány v kontejnerech s prosklenými stěnami pod zátěží 5,1 kPa během celého vegetačního období. Za podmínek tohoto tlaku a neměřených podmínek hypoxie se prokázala snížená rychlost, změněná časová dynamika růstu kořenů a snížená schopnost obsazovat půdní prostor. Konkrétně např. celková plocha kořenových systémů experimentálních sazenic byla o 52 % nižší, avšak hodnota RAI (root area index) byla u zatížených kořenů o 33 % vyšší oproti kontrolním sazenicím. To znamená, že tlakem na půdní povrch vytvořily sazenice kořenový systém nejen menší, ale i nahloučený do menšího půdního prostoru. Také průměrný délk (cs)
