Development of effective biocontrol procedures using ash endophytes to combat an pathogen Hymenoscyphus fraxineus would be appropriate contribution the ongoing effort protect European stands against decline. In this study we investigated potential two endophytes, Thielavia basicola and Minimidochium sp., H. in vitro plant-fungus fungus-fungus dual cultures approach three models. The tests aimed...

In this study, four specimens belonging to Karaj mycoflora were examined. According to the results, two form – species; Diplosporonema delastrei, on Silene latifolia subsp. persica and Piggotia ulmi, on Ulmus sp. are reported with new names. For some of the identified fungal specimens, new hosts (matrix nova) are introduced. Moreover, many taxa such as , Marssonina kriegeriana on Salix sp.,  Se...

Phytochemical investigation of the leaves of Fraxinus griffithii has led to the isolation of two new glucosylated acyclic sesquiterpene alcohols, griffithosides D (1) and E (2), along with iridoid and secoiridoid glycosides. The molecular structures of these compounds were elucidated using NMR, MS and other spectroscopic techniques, as well as comparison with literature data. The isolated compo...

Ash (Fraxinus) is an economically important tree genus in the landscape industry, as well as a key component of North American forests, especially in the North Central United States and adjacent regions in Canada. In recent years, the Emerald Ash Borer beetle (Agrilus planipennis) has significantly threatened the survival of native North American Fraxinus species. A dormant-bud cryopreservation...

Abstract Pyrenochaeta fraxinina was first described in 1913 from the state of New York (USA) on petioles Fraxinus sp. Since then, species has not been reported North America and reports other regions world are very sparse. The results this study P . based material collected various Poland 2012 to 2019. comprised 2700 previous year’s leaf excelsior 1970 or residues eight deciduous tree species. ...

The aim of the research was to present current data on distribution and development some alien phytophagous insects in territory Ukraine.We considered 19 species insects, including 2 Coleoptera, 7 Hemiptera (including 4 bug species), Lepidoptera, Hymenoptera, 1 Diptera. Hyphantria cunea penetrated Ukraine about 70 years ago sometimes outbreaks orchards or shelterbelts. Cameraria ohridella Cydal...

PREMISE OF THE STUDY Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleac...
