The European white elm (Ulmus laevis) is a fast-growing, medium-sized, deciduous tree mostly distributed across Central and Eastern Europe. Surface root structure exposed by bank erosion, Like other European elms, natural populations of the European white elm have little innate resistance to Dutch elm disease, although research by Irstea has isolated clones able to survive inoculation with the causal fungus, initially losing < 70% of their foliage, but regenerating strongly the following year. Five U. laevis populations … glabra). How to Grow Stokes Aster From Seed. Its roots form distinct buttressing at the base of the trunk. Danihelka J., Chrtek J. Jr. & Kaplan Z. laevis; Ulmus laevis … Ulmus laevis Pall., variously known as the European white elm,[1] fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France[2] northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and Spain, the latter now considered a relict population rather than an introduction by man, and possibly the origin of the European population. Unlike many varieties of aster, Smooth Blue Asters produce perfectly smooth foliage and stems. The cultivar was cloned from a tree planted as one of a line of 17 White Elms at Eibergen circa 1900, which developed a straight central leader. Ulmus glabra Huds. Dry samaras of U. laevis had higher floatability and lower air sustentation than those of U. minor. In the past the leathery … Several putative varieties have been identified. Identified as those of the European white elm, Ulmus laevis, hitherto unknown in Ireland, the seeds were grown by Coillte into 15,000 saplings. Seed at center or toward apex of samara, compressed or ± convex, without endosperm; embryo erect; cotyledon flat or ± convex. Significantly, the leaf veins do not divide from the central vein to the leaf margin. Oliver Rackhamdescribes Ulmus as the most critical genus in the entire British flora, adding that 'species and varieties are a distinction in the human mind rather than a measured degree of genetic variation'. Ulmus; Ulmus laevis; The strong-growing Russian elm, despite the common name, is also native to Finland though it is seldom planted and little known nowadays. Litvinov (1908) considered it a species, calling it Ulmus celtidea Litv., a view … Survival, height and diameter growth of two species were … Status . Ei… Ulmus laevis var. Solla et al.

Compared with the other European species of elm, U. laevis has received scant horticultural attention, there being only eight recorded cultivars: In Russia other ornamental forms are recognized: f. argentovariegata, f. rubra, and f. tiliifolia. In Ireland, the tree is represented by a line of four at the Old Rectory, Kells Road, Ardee, County Louth (22 m or 72 ft, girth 3 m or 9.8 ft, October 2009),[54] and in the Channel Islands, by a clump near the well at La Seigneurie (Le Manoir), Sark.[53]. Ulmus laevis populations tend to be small, and many are thought to be at risk of losing genetic diversity via random drift. A lane of Ulmus laevis is found at Eibergen, Netherlands (see Gallery below), while a large, mature specimen is found within the Alhambra, Granada. Girard, S. (2007).

However, owing to its rapid growth, tolerance of soil compaction, air pollution and de-icing salts, the tree has long been used for amenity planting in towns and along roadsides.[7]. Indeed, in a study of elm in Flanders, not one example of U. laevis was found to be afflicted by Dutch elm disease. The quality of firewood is poor as well. (2005). Ulmus laevis; Ulmus laevis. [30] In the Far East, the tree has been planted in Xinjiang province and elsewhere in northern China; planting in Tongliao City is known to have been particularly successful. Linear regression identified seed removal by rodents to be frequency‐independent both over the woodland as a whole and within each of six micro‐habitats. Probably more common in Portland than has been recorded. This is due to its cross-grained wood making it difficult to process. long (sometimes more on young trees) 1 1 ⁄ 2 to 4 in. - iForest (early view): e1-e8 . [15] The species was not reported from the wild until 1943, with the discovery of a tree in a Surrey hedgerow. In the first experimental week, seeds were germinated in 4 L pots filled with perlite.

Ulmus laevis These Technical Guidelines are intended to assist those who cherish the valuable white elm genepool and its inheritance, through conserving valuable seed sources or use in practical forestry. This appeared to be a result of the … Use sharp pruning shears to cut the seed pod from the tree. It adapts to a wide variety of environments, though it can usually be found growing in open woodland, along … Flood control schemes are particularly harmful, as seed dispersion is reliant on floods, while abstraction from aquifers lowering ground water levels has compromised the development of the trees. In the province of Häme it is a typical species of the shores of Lake Vanajavesi, in rich forest soils achieving a diameter of over a metre, given a few centuries. The Tree is a deciduous tree, it will be up to 40 m (131 ft) high. The seeds have a generally high rate of germination, 45–60% for Serbian trees examined by Stilinović.

Although not possessed of an innate genetic resistance to Dutch elm disease, the species is rarely infected in western Europe.[7]. Endemic to alluvial forest, U. laevis is rarely encountered at elevations above 400 m.[8] Most commonly found along rivers such as the Volga and Danube, it is one of very few elms tolerant of prolonged waterlogged, anoxic ground conditions. The flowers are green-violet to purple.

Screening European Elms for Resistance to Ophiostoma novo-ulmi. Ulmus laevis is similar in stature to the wych elm, if rather less symmetric, with a looser, untidy, branch structure and less neatly rounded crown. The tree is most reliably distinguished from other European elms by its long flower stems, averaging 20 mm. Ulmus laevis trunk and branches in spring habitus, early + late April Flowers . Ulmus minor P-VV1 genotype seeds (the code refers to the Spanish Elm Breeding Program) were collected at Puerta de Hierro nursery (Madrid, 40°27’N, 3°45’W) conservation plot, and U. laevis M-VD.R29 genotype seeds (referring to the Spanish Elm Breeding Program) at Valdelatas forest (Madrid, 40°32’N, 3°40’W). A tree from 100 to 125 ft high, with a trunk sometimes 6 ft in diameter; head of branches wide-spreading, rather open; young shoots stout, downy; bud scales hairy. [45], U. laevis, obtained from the Späth nursery of Berlin as U. effusa, was planted in Kew Gardens (1895),[14] in the Ryston Hall arboretum, Norfolk (1914),[46][47] and, re-propagated, in Cambridge University Botanic Garden (1909). [27] In England, the tree failed to prosper in chalk stream valleys, where the soil was predominantly black peat, named 'Adventurers' for the Adventurers' Land SSSI in Cambridgeshire, owing to dehydration in summer. In Europe, it is the unique example of the European White Elm Ulmus laevis which has received the most attention. Ulmus laevis var. A deciduous tree, formerly planted but now rare and found in only a few woods and river banks. Ulmus laevis seedlings of one provenance were grown in beds with 20 cm between rows and different spacing within rows (2.9, 3.3, 5.0 and 6.7 cm).

Pl. [9] The leaves are deciduous, alternate, simple ovate with a markedly asymmetric base, < 10 cm long and < 7 cm broad, comparatively thin, often almost papery in texture and very translucent, smooth above with a downy underside. Elm tree seeds are small and round and are protected in an oval papery casing called a samara. Vander Mijnsbrugge, K., Vanden Broeck, A., & Van Slycken, J. There are about 30 to 40 species of Ulmus (elm); the ambiguity in number results from difficulty in delineating species, owing to the ease of hybridization between them and the development of local seed-sterile vegetatively propagated microspecies in some areas, mainly in the field elm (Ulmus minor) group. The branches of the elm are olive brown. About 40 species: Asia, Europe, North America; 21 species (14 endemic) in China.
