The Water, especially if it is limited, is one of the key abiotic stress factors for forests and landscape. The article analyzes the water balance, drought and flood conditions in temperate climate zone based on the scientific studies in Slovakia, the Czech Republic, Germany and Central Europe.

An experiment under controlled conditions to assess the suitability of thermal imaging as a new method for identifying physiologically weakened trees was running. The measurements were carried out at three treatments with different rainwater regime - covered, semi-covered and control. Trees were...

Among the environmental stressors that limit environmental functions of trees, the first place takes lack of water. Some tree species are well adapted to frequent and prolonged periods of drought. They are able to grow and bear even high degree of dehydration. These properties have to be detected...

Sweet chestnut (Castanea sativa Mill.) as an introduced species in Slovakia is the object of our research in terms of morphometric analysis of fruits from randomly selected 30 genotypes from the repository Príbelce with presence of old varieties, biennial seedlings of intraspecific and...

One part of mature spruce stand was covered by roof and the second one was left as the control plot. On the selected 6 Norway spruce individuals for each part we performed the continuous sap flow measurements. The measurements of basic meteorological variables were performed on nearby clearing....

Norway spruce (Picea abies (L.) H. Karst) trees at the newly created forest edges are suddenly more radiated and heated, and they produce more terpenes - primary insect pest attractants. Therefore, spruce forest edges are thought to have a higher predisposition for the infestation by bark beetle ...

The aim of the research was to evaluate the floristic composition and quality of phytomass of localities with mass occurrence of juniper at various altitudes: Ostrá hora (568 m a.s.l.), Kišovce (667 m a.s.l.), Priechod (576 m a.s.l.) and Iliaš (440 m a.s.l.). Grasslands with juniper were specific...

The content of cadmium in the poppy plants 'Maratón' was monitored in the container experiment as well as the effect of this metal on the concentration of malondialdehyde (MDA), total phenolic content (TPC) and total flavonoids content (TFC) over the course of five weeks. The plants were treated...

The paper analyzes the balance of soil water in the spruce stand mountain conditions in the Upper Orava region, Slovakia. The long-term research (1991-2014) shows that the predominant moisture interval in the vegetation period (V-X) is semi-uvidic soil interval (MCC-PDA) with a good or sufficient...

City settlements in the worldwide are characterized by a high concentration of human population and deteriorating of their environment. These are caused by an emission impact, both global and local climate change. The city is characterized as a thermal island. The current environmental quality of...
