[4] Die Blattoberseite ist kahl bis schuppig. A prime example of the species was the Sauble Elm,[3] which grew beside the banks of the Sauble River in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to DED; when it was felled in 1968, a tree-ring count established that it had germinated in 1701. Other artificial hybridizations with American elm are rare, and now regarded with suspicion. [3][2], Bei Ulmus americana handelt es sich um einen Phanerophyten.

Werthner, discussing the contrast between open-grown and forest-grown American elms, noted that: In the open, with an abundance of air and light, the main trunk divides into several leading branches which leave the trunk at a sharp angle and continue to grow upward, gradually diverging, dividing and subdividing into long, flexible branchlets whose ends, at last, float lightly in the air, giving the tree a round, somewhat flattened top of beautifully regular proportions and characteristically fine twiggery.[9]. In wet to mesic often nutrient rich soils. Versuche, diese Anfälligkeit durch Kreuzungen mit anderen Ulmen zu vermeiden, haben bisher noch nicht zu durchschlagenden Erfolgen geführt, weil resistente Arten zugleich mit Nachteilen behaftet sind.

American Elm is wholly insensitive to daylight length (photoperiod), and will continue to grow well into autumn until injured by frost. There is some reason to hope that these elms will preserve the genetic diversity of the original population, and that they eventually will hybridize with DED-resistant varieties that have been developed or that occur naturally. [9] On more elevated terrain, as in the Appalachian Mountains, it is most often found along rivers. Oktober 2020 um 19:35 Uhr bearbeitet. The trees are particularly noteworthy along the Mall and Literary Walk, where four lines of American elms stretch over the walkway forming a cathedral-like covering. The cutting was planted, cuttings were then taken from it, including one planted on February 18, 1932, the 200th anniversary of the birth of George Washington, for whom Washington state is named.

Wiąz amerykański, zwany potocznie także wiązem białym lub wiązem wodnym jest gatunkiem występującym w Północnej Ameryce. [63], While the stand is still vulnerable to DED, in the 1980s the Central Park Conservancy undertook aggressive countermeasures such as heavy pruning and removal of extensively diseased trees. [8], The American elm occurs naturally in an assortment of habitats, most notably rich bottomlands, floodplains, stream banks, and swampy ground, although it also often thrives on hillsides, uplands and other well-drained soils. U. americana is also the most susceptible of all the elms to verticillium wilt,[17] whose external symptoms closely mimic those of DED.

Introduced to the UK by James Gordon[3] in 1752, the American elm was noted to be far more susceptible to insect foliage damage than native elms. The website also provides access to a database and images of herbarium specimens found at the University of South Florida and other herbaria. [33] In 2007, AE Newhouse and F Schrodt of the State University of New York College of Environmental Science and Forestry in Syracuse reported that young transgenic American elm trees had shown reduced DED symptoms and normal mycorrhizal colonization.

Entlang des nordwestlichen Verbreitungsgrenze gedeiht sie meist nur auf Talböden entlang von Wasserläufen. 'Princeton' has been in occasional cultivation since the 1920s, and gained renewed attention after its performance in the same screening tests showed it also to have a high degree of disease resistance. It is hardy to zone (UK) 3 and is not frost tender.

On more elevated terrain, as in the Appalachian Mountains, it is most often found along rivers. Then known as the Survivor Tree, it became an important part of the Oklahoma City National Memorial, and is featured prominently on the official logo of the memorial. [9] Later, with the advent of mechanical sawing, American elm wood was used for barrel staves, trunk-slats, and hoop-poles, and subsequently became fundamental to the manufacture of wooden automobile bodies, with the intricate fibers holding screws unusually well.

Mary Eleanor Wilkins Freeman, in her book of short stories Six Trees, wrote of the American elm: Numerous cultivars have been raised, originally for their aesthetic merit but more recently for their resistance to Dutch elm disease[27] The total number of named cultivars is circa 45, at least 18 of which have probably been lost to cultivation as a consequence of DED or other factors: The US National Elm Trial, begun in 2005, evaluated four American elm cultivars in scientific plantings across the United States to better assess their strengths and weaknesses.[28]. [29] The United States National Arboretum released 'Valley Forge' and 'New Harmony' in late 1995, after screening tests performed in 1992–1993 showed both had unusually high levels of resistance to DED. Insignificant flowers appear in March or April and bloom before the leaves emerge. Early photos of New England American elms, showing growth patterns, The New International Encyclopædia (1905). The flowers are also protogynous, the female parts maturing before the male, thus reducing, but not eliminating, self-fertilization,[6] and emerge in early spring before the leaves. It is this distinctive growth form that is so valued in the open-grown American elms of street plantings, lawns, and parks; along most narrower streets, elms planted on opposite sides arch and blend together into a leafy canopy over the pavement.
