Climate change represents one of the major environmental problems of our time (IPCC, 2021), significantly affecting plant water regimes and agricultural production. Increased temperatures, prolonged droughts, and unpredictable rainfall patterns lead to reduced soil water availability (Allen et al., 1998), increasing the urgency for efficient and precise irrigation management. As traditional methods based on soil moisture or empirical models become less effective under variable climatic conditions (Jones, 2004), th...

THE IMPACT OF SOILWATER STORAGE ON THE RADIAL CHANGES OF THE ROYAL WALNUT (JUGLANS REGIA L.)

(STEF92 Technology, 2020-12-20, Martina Kovacova, Viliam Bárek)

Show more

Climatic conditions have significantly changed over the last decades. In the middle latitude, the annual precipitation total does not change significantly, but precipitation is unevenly distributed throughout the year. The aim of the research is to investigate the effects of climatic conditions on the dendrological changes of the Royal walnut (Juglans Regia L. var. Chandler) in the period from July to November 2020 in the conditions of the middle latitude of southern Slovakia. This area is characterized by intensi...

SAP FLOW AS A POSSIBLE INDICATOR OF WATER STRESS

(STEF92 Technology, 2019-06-20, Viliam Bárek)

Show more

Climate change is defined as a significant difference between two mean climatic states, with substantial impact on the ecosystem. Extreme climatic events, such as higher temperatures, more intense precipitation, increased drought risk and duration as well as cyclones and flooding in coastal areas, are expected to increase in both frequency and intensity. One of the possible indicators of water stress is sap flow measurement. For this experiment were used the apple trees in Nove Zamky, Slovakia. On stem were instal...
