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. 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]. 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. We investigated fruit release timing and rates, and how these are affected by meteorological variables with generalized linear models. Neophyte.

A fragment of an elm tree blossoming . Several putative varieties have been identified. A lane of Ulmus laevis is found at Eibergen, Netherlands (see Gallery below), while a large, mature specimen is found within the Alhambra, Granada. Research in Spain has indicated that it is the presence of an antifeedant triterpene, alnulin, at a concentration of 200 μg/g {dried bark} which renders the tree unattractive to the beetles.

Seeds of elm wood. [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). (2000). 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. Moreover, a small number of trees found in Spain is now considered a relict population rather than an … is a putative variety of European White Elm first described by Rogowicz, who found the tree in 1856 along the river Dnjepr near Chernihiv in what is now northern Ukraine. This species reproduces through suckers instead of seeds and was abundant in England before the advent of Dutch Elm disease. The effect of temperature and light on the germination performance of Ulmus minor, Ulmus glabra and Ulmus laevis were studied in this research. Status . The top bends … celtidea; Ulmus laevis var. [14][15] The American elm also has less acute leaf buds, longer petioles, narrower leaves, and a deeper apical notch in the samara which reaches the seed.

Many species yield fine woods, edible … Cut off the seed pod that grows on the Ulmus parvifolia tree during the fall when the pod is still green but fully grown. The extensive shallow root system ultimately forms distinctive high buttresses around the base of the trunk. [42] James Main mentions the tree as 'a native of Hungary' and in 1838 only to be met in 'ornamental plantations',[44] but by 1846 was 'becoming available in (UK) nurseries'.
