Abstrakt ve sborníku z konference TRACE 2017 - Tree rings in archaeology, climatology and ecology, 16. - 21. 5. 2017, Svetlogorsk, Rusko: Sign of air pollution calamity in anatomical features of spruce (Picea abies (L.) Karst) in the Klínovec area (Ore mountains)

Popis výsledku v původním jazyce

Fossil fuel emissions caused one of the globally highest pollutant deposition. Upper parts of the Ore mountains have been stressed mainly by the sulphur dioxide for a long period of time especially in 70s and 80s of 20th century. That is why is the region of northern Bohemia and neighbouring parts of Saxony and Poland often called black triangle. Klínovec area is thanks to combination of altitude, low temperatures occurrence and presence of pollution fundamentally model locality. Data produced using quantitative wood anatomy method can serve us as sensitive indicator of environmental changes. Research deals with how enormous pollution loads together with frost can affect microscopic structure of old spruce stand wood. Values of anatomical features for period before, during and after highest pollution loads as number of tracheids, lumen area, cell wall thickness and tree ring width from three localities nearby Klínovec hilltop at altitude around 1 000 m.a.s.l. and from one locality at the hilltop (1 244 m.a.s.l) have been measured for individual years and compared. Number of cells together with tree ring width seems to be the most responsive feature. Increasing of feature values after stress period is apparent.
