Nature: Mating system and population genetic structure of an androdioecious tree, Fraxinus lanuginosa Koidz. (Oleaceae) in northern Japan To test this hypothesis, we used electrophoretic allozyme methods to study the mating system and population genetics of an androdioecious tree, Fraxinus lanuginosa, which exhibits large variations in ... Mating system and population genetic structure of an androdioecious tree, Fraxinus lanuginosa Koidz.
(Oleaceae) in northern Japan Fraxinus (/ ˈfræksɪnəs /), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, [4] and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous (dropping their leaves in autumn), although some subtropical species are evergreen. ash, (genus Fraxinus), genus of 45–65 species of trees or shrubs (family Oleaceae) primarily distributed throughout the Northern Hemisphere. Several species are valuable for their timber and beauty. A few species extend into the tropical forests of Mexico and Java.
fraxinus lanuginosa, Ash (Fraxinus spp.) Identification Fraxinus spp. Characteristics Hosts Ash trees (Fraxinus spp.) are the only known North American hosts of EAB. Ashes have pinnately compound leaves arranged opposite one another on the branch. Each leaf bears 5-9 leaflets. The fruit is a winged seed (samara).
fraxinus lanuginosa, White ash (Fraxinus americana), also called Biltmore ash or Biltmore white ash, is the most common and useful native ash but is never a dominant species in the forest. It grows best on rich, moist, well-drained soils to medium size. There are 40–50 species of Fraxinus, distributed primarily in the temperate and subtropical northern hemisphere (Wallander & Albert 2000). They are typically deciduous trees, though evergreen and shrubby species occur.
