Non-destructive monitoring of early stages of white rot by Trametes versicolor in Fraxinus excelsior
We studied the impact of neophyte tree Fraxinus pennsylvanica on diversity beetles in floodplain forests along river Elbe Germany 2016, 2017 and 2020, where 80% all excelsior trees had died following severe droughts. Beetles were collected by insecticidal knock-down from 121 (64 F. 57 pennsylvanica) identified to 547 species 15,214 specimens. The sampled 2016 showed no signs drought stress or a...
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 ...
Ash dieback is a recent widespread disease on ash (Fraxinus sp.) that is causing important economic and ecological losses throughout Europe. The disease is initiated by the ascomycetous fungus Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea). The main aim of this study was to investigate seasonal pattern of lesion development associated with ash dieback. We present data on the spread of ...
This study was carried out in Kovada lake national park Isparta 2018-2020 to determine the forage values of common grazeable bush species. Ten species including bush, shrub-shaped tree and shrub (Phillyrea latifolia, Spartium junceum, Juniperus oxycedrus, Quercus coccifera, infectoria, Coronilla emerus, Colutea melanocalyx, Fraxinus excelsior, Paliurus spina-christi ve Crataegus monogyna) were ...
Tree seedling flooding tolerance for 22 species was assessed under controlled field condi tions. Initial heights under control (freely draining soil, n = 20 per species) and flooded (stand ing water, depth = 10 cm, n = 20 per species) conditions were measured in March 1990. Sur vival, height and diameter growth were determined after 120 days. Recovery from flooding effects was assessed in th...
