The response of Norway spruce and European beech's photosynthetic apparatus to some stress factors - comparative study
 NOVÁKOVÁ, Hana
In the context of expected climate changes is more and more important to study how will species of present ecosystems react to this changes. Thus this study is focused on reactions of two main forest tree species of Central Europe ? Norway spruce (Piacea abies L.) and European beech (Fagus sylvatica L.) ? to water stress, higher quantity of N in soil, combination of theese stress factors and heat stress. The effects of stress were monitored on maximal photochemical efficiency of PS II (Fv / Fm) and on contents of photosynthetic pigments. It was found that Norway spruce is more resistant to all mentioned stress factors than European beech.
