in order to assess the adaptation of elaeagnus angustifolia l. and fraxinus rotundifolia mill afforestation around tabriz international airport, the qualitative and quantitative characteristics of trees were measured in 96 experimental circular plots with a size of 300 m2. to study the edaphic effects of these species, nine samples were randomly collected from 0-10 cm and 10-20 cm depth of soil...

Emerald ash borer (EAB), Agrilus planipennis, is a phloem-boring beetle, native to East Asia that has become serious invasive pest of (Fraxinus spp.) trees in North America and European Russia since the early 2000s. In 2019, EAB was detected Ukraine. It had spread over 300 km from entry point two years killed hundreds Fraxinus excelsior F. pennsylvanica trees. poses threat forests neighboring c...

Wood residues produced from forestry activities represent an interesting source of biologically active, high value-added secondary metabolites. In this study, 30 extracts from 10 barks of deciduous and coniferous tree species were investigated for their potential dermo-cosmetic use. The extracts were obtained from Fagus sylvatica, Quercus robur, Alnus glutinosa, Prunus avium, Acer pseudoplatanu...

Spatial genetic structure was analysed with five highly polymorphic microsatellite loci in a Romanian population of common ash (Fraxinus excelsior L.), a wind-pollinated and wind-dispersed tree species occurring in mixed deciduous forests over almost all of Europe. Contributions of seed and pollen dispersal to total gene flow were investigated by analysing the pattern of decrease in kinship coe...

A natural extract obtained from the seeds of Fraxinus excelsior L. (FraxiPure™) has been previously reported to reduce glycemia in animal models and in humans. The objective of this work was to evaluate the safety of FraxiPure™ at in vitro, in vivo and human levels. In addition, nutritional analyses revealed an extract high in carbohydrates, with minor levels of protein, dietary fiber, glucose ...

The present work evaluates and compares the antioxidant capacities of bioactive constituents in barks ten common wood species from Hungary (Quercus rubra, Prunus serotina, Quercus robur, Betula pendula, Fraxinus excelsior, Robinia pseudoacacia, Carpinus betulus, Picea abies, Alnus glutinosa, Pinus sylvestris). Low-frequency ultrasound was used for intensification extraction bark to obtain extra...

Tree species differ in their physiological responses to drought, but the underlying causes are often unclear. Here we explored of radial growth centennial drought events and sap flow (Fs) seasonal four mixed forests on either moist or drier sites northwestern Switzerland. While diffuse-porous (Fagus sylvatica, Prunus avium, Tilia platyphyllos) showed marked reductions 1976 2003, two known marke...
