Forests worldwide are currently threatened by a number of non-native tree diseases. Widespread death of a tree species will have ecological impacts on species that in some way depend on that tree species to complete their life-cycle. One measure to mitigate these impacts is to establish alternative tree species to replace the threatened tree species. These alternative tree species should be as ...

Background and Purpose: Common ash (Fraxinus excelsior L.) is a species with a widespread distribution in Europe. It mostly grows on mesophyll sites, mainly in karst valleys and by forest creeks, and in Herzegovina at northern expositions and higher altitudes with somewhat better types of soil. Materials and Methods: We studied 10 natural populations. We collected dormant buds with branches fro...

Abstract The existence of European ash ( Fraxinus excelsior L.) is threatened by fungus-induced dieback. It essential to find effective methods multiply genotypes resistant dieback while preserving the genetic diversity these tree populations. In this paper efficient method for production seedlings using indirect auxiliary organogenesis with multi-factor analysis its effectiveness presented. Pr...

The ongoing fragmentation of ash populations due to dieback requires an effective gene flow between individuals; thus, investigations on pollen transport are essential. In this study, comprehensive aerobiological field experiments at two seed plantations in Baden-Württemberg were conducted 2019 and 2020 order study the influence phenology meteorology (especially wind) using self-constructed gra...
