Previous studies of Ulmus pumila Linnaeus and Ulmus rubra Muhlenberg and their hybrid Ulmus x notha Wilhelm and G. Ware were restricted mainly to investigations of Dutch elm disease resistance/breeding for the cultivar trade. Recent studies have focused on and distribution and descriptions of phenotypic characters of these taxa. Ulmus pumila L.

A study of vegetative propagation has been carried out using cuttings of three elm species: Ulmus minor Mill, Ulmus laevis Pall. and Ulmus pumila L. The objective of the study was to determine their survival rate and growth under different concentrations of IBA (indole-3-butyric acid) solutions. The hormonal treatments consisting of 0, 2,000, 3,000 and

Time of Floral Differentiation in Ulmus americana, U. pumila, and U. carpinifolia
Botanical Gazette, 19591. Buds from flowering trees and young non-flowering trees of Ulmus americana L., U. pumila L., and U. carpinifolia Gleditsch were collected through two growing seasons. The collections were made at intervals from May 9, 1955, to February 24, 1956, and from June 5, 1956, to July 25, 1956. 2.

Flora - Morphology, Distribution, Functional Ecology of Plants, 2011
Abstract The potential natural distribution of deciduous forests in Central Asia is the subject of ongoing discussions. Ulmus pumila (Siberian elm) is the only tree species occurring in southern and south-eastern Mongolia. In the semi-arid Mongolian Gobi, the species is restricted to ravines and beds of semi-temporary rivers.

A Report on Ulmus Pumila in the Great Plains Region of the United States
Journal of Forestry, 1948Abstract From a study of the history of oriental elms that have been planted in the Great Plains, the author concludes that Ulmus pumila should properly be called Siberian elm and U. parvifolia Chinese elm. Trees of U. pumila originating from seed collected from the southern part of the natural range in China have been found ...

Hepatoprotective and neuroprotective flavanes from the fruits of Ulmus pumila L. (Ulmaceae)
Pakistan Journal of Pharmaceutical Sciences, 2019Phytochemical study of the EtOAc fraction (active extract) of the fruits of Ulmus pumila L. resulted in the isolation of thirteen flavane derivatives, and they were identified by their precise spectral data and literature. All the compounds (1-13) were obtained from the fruits of U. pumila L. for the first time.

Effect of humic fertilizer on the growth and development of Ulmus pumila L. hybrids
PrirodoobustrojstvoIn arid regions, forest strips are one of the most important natural resources. The use of modern preparations that improve the growth and development of plants will allow the most complete and effective cultivation of planting material and meet the need for various types of forest products. Squat elm (Ulmus pumila L.) has increased resistance to
