Micropropagation of common ash (Fraxinus excelsior)

Plant Cell, Tissue and Organ Culture (PCTOC), 1992
Embryos extracted from dried seeds of common ash (Fraxinus excelsior), were germinated on growth regulator-free culture medium. Cotyledonary nodes from these seedlings were placed onto Murashige and Skoog, Woody Plant or Driver and Kuniyuki culture media with 22.2 or 44.4 μM benzyladenine, on which they developed into shoot cultures following the ...

Fraxinus excelsior L. (Common Ash)

, 1996
Fraxinus (family Oleaceae) is a genus of approximately 50 species of hardwood trees and shrubs found in Europe, N. Africa, W. Asia and N. America. Although there are several Fraxinus spp. growing in Europe, only common ash (F. excelsior L.) is found in woodlands in the British Isles (Fig. la). Important North American species include F.

Using the ash of common water reeds as a silica source for producing high purity ZSM-5 zeolite microspheres

Microporous and Mesoporous Materials, 2021
Utilizing of ash extracted from Iraqi common water reeds as an inexpensive effective silica source in the preparation of ZSM-5 zeolite was investigated for the first time in the present work.

Plant regeneration of common ash (Fraxinus excelsior L.) by somatic embryogenesis

In Vitro Cellular & Developmental Biology - Plant, 2007
This is the first report on somatic embryogenesis in common ash (Fraxinus excelsior L.). Experiments on somatic embryogenesis induction were carried out on zygotic embryos at different phases of development and maturation. The embryo axes were isolated and cultured on media containing different plant growth regulators (PGRs).

Common ash (Fraxinus excelsior L.) seeds as a new vegetable oil source

, 2020
In this study, common ash (Fraxinus excelsior L.) seed oil compositions were determined for the first time. Effect of the moisture content and microwave pretreatment of the seeds on the oil yield and its composition were also investigated.

A generalized heterozygote deficiency assessed with microsatellites in French common ash populations

Molecular Ecology, 2002
AbstractCommon ash is a temperate forest tree with a colonizing behaviour, a discontinuous spatial distribution and a peculiar and poorly known mating system. Microsatellite markers were used to study the genetic structure in natural populations of common ash. Twelve populations located in northeastern France were analysed at five loci.

Evaluation of ash composition and deposition tendencies of biomasses and torrefied products from woody and shrubby feedstocks: SRC poplar clones and common broom

Fuel, 2020
This work intended to compare ash composition and deposition tendencies biomasses and of torrefied products of SRC poplar clones and common broom. These biomasses were assessed in a previous study as these delivering torrefied products with better fuel ...

Micropropagation of Fraxinus excelsior L. (Common Ash)

1997
Fraxinus (family Oleaceae), also called ash, is a genus of about 65 species of deciduous trees and a few shrubs, scattered over the cool temperate parts of the Northern Hemisphere (Harrison 1967; Savill 1991). Ashes are rugged trees which build themselves up into fairly large, strongly branched structures, well known for their black winter buds, for ...

Regeneration of shoots from embryo hypocotyls of common ash (Fraxinus excelsior)

Plant Cell Reports, 1992
The addition of thidiazuron (TDZ) to MS salts and vitamins, instead of benzylaminopurine (BAP) increased both the culture weight and the proportion of ash embryo hypocotyl explants that produced adventitious shoots. The concentration of BAP, but not that of TDZ also affected these parameters.

Estimating seed vs. pollen dispersal from spatial genetic structure in the common ash

Molecular Ecology, 2003
AbstractSpatial 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.
