Cryopreservation of dormant European ash (Fraxinus excelsior) orthodox seeds.
We investigated the sensitivity of dormant Polish-provenance Fraxinus excelsior L. seeds to extreme desiccation and liquid nitrogen (LN, -196 degrees C). Germination and seedling emergence tests revealed that the critical water content (WC) of the desiccated seeds was 0.04-0.06 g H(2)O g(-1) dry mass, g g(-1) (0.04 g g(-1) in the germination test and 0.06 g g(-1) in the seedling emergence test)...
متن کاملGenetic Characterization of Common ash (Fraxinus excelsior L.) populations in Bosnia and Herzegovina
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...
متن کاملGenetic Structure in the Northern Range Margins of Common Ash, Fraxinus excelsior L.
During post glacial colonization, loss of genetic diversity due to leading edge effects may be attenuated in forest trees because of their prolonged juvenile phase, allowing many migrants to reach the colonizing front before populations become reproductive. The northern range margins of temperate tree taxa in Europe are particularly suitable to study the genetic processes that follow colonizati...
متن کاملMolecular markers for tolerance of European ash (Fraxinus excelsior) to dieback disease identified using Associative Transcriptomics
Tree disease epidemics are a global problem, impacting food security, biodiversity and national economies. The potential for conservation and breeding in trees is hampered by complex genomes and long lifecycles, with most species lacking genomic resources. The European Ash tree Fraxinus excelsior is being devastated by the fungal pathogen Hymenoscyphus fraxineus, which causes ash dieback diseas...
متن کاملApplication of ash (Fraxinus excelsior L.) roots to determine erosion rates in mountain torrents
Due to the effect of global change, the potential risk of natural hazards occurring in alpine areas is expected to increase to an even higher risklevel than has been recorded during the last century. These global changes potentially also have distinct influences on fluvial processes in torrents causing erosion on slopes and riverbanks in forested areas. Dating the time of root exposure along ri...
