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 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...
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 کاملGene flow of common ash (Fraxinus excelsior L.) in a fragmented landscape
Gene flow dynamics of common ash (Fraxinus excelsior L.) is affected by several human activities in Central Europe, including habitat fragmentation, agroforestry expansion, controlled and uncontrolled transfer of reproductive material, and a recently introduced emerging infectious disease, ash dieback, caused by Hymenoscyphus fraxineus. Habitat fragmentation may alter genetic connectivity and e...
متن کاملChloroplast DNA variation and postglacial recolonization of common ash (Fraxinus excelsior L.) in Europe.
We used chloroplast polymerase chain reaction-restriction-fragment length polymorphism (PCR-RFLP) and chloroplast microsatellites to assess the structure of genetic variation and postglacial history across the entire natural range of the common ash (Fraxinus excelsior L.), a broad-leaved wind-pollinated and wind-dispersed European forest tree. A low level of polymorphism was observed, with only...
