Causes and trends in pathological damage to common ash

Наукові доповіді Національного університету біоресурсів і природокористування України
Intensive dieback of Fraxinus excelsior L. in the Forest-Steppe zone of Ukraine has led to a significant deterioration in the sanitary condition of ash stands and increased the risk of losing their ecosystem stability, making this issue particularly ...

Temporal development of collar necroses and butt rot in association with ash dieback

iForest - Biogeosciences and Forestry, 2017
In recent years collar necroses and butt rot associated with the ash dieback disease occurred with alarming frequency in Fraxinus excelsior. We analysed tree ring structures to identify the year of necrosis initiation on a set of 507 necroses on 155 stem

Phytophthora-free plant production and update on Hymenoscyphus fraxineus

, 2018
In order to minimize the risk of spreading Phytophthora species to forests and ornamental sites via nursery stock, BFW has been performing checks of plants of Common Alder (Alnus glutinosa) and European beech (Fagus sylvatica) from forest nurseries for contamination with Phytophthora spp. on a service-basis for the past 13 years.

Phenotypic variability of Fraxinus excelsior L. and Fraxinus angustifolia Vahl under the ash dieback disease in the Czech Republic

Journal of Forest Science, 2018
The study was carried out in the experiment with 16 provenances of common ash (Fraxinus excelsior Linnaeus) and 2 provenances of narrow-leaved ash (Fraxinus angustifolia Vahl) at a series of 5 parallel trial plots established in a gradient from lowland ...
