Using Ulmus pumila (Siberian Elm) leaf unfolding and leaf fall phenological data from 46 stations in the temperate zone of China for the period 1986-2005, we detected linear trends in both start and end dates and length of the growing season. Moreover, we defined the optimum length period during which daily mean temperature affects the growing season start and end dates most markedly at each. Occasional plants in weedy settings that have the growth habit of Ulmus pumila, but with larger and somewhat scabrous leaves and a strong tendency for the leaves of rapidly growing (indeterminate) terminal shoots to be much larger than the leaves of shorter shoots, are apparent hybrids with U. rubra Siberian Elm Ulmus pumila is Naturalized in Texas and other States and is considered an invasive plant in Texas. Positive On Nov 19, 2006, lkz5ia from Denison, IA (Zone 5b) wrote Ulmus pumila is considered an invasive tree in 41 of the United States. In this study, we examined the extent of hybridization in naturalized populations of U. pumila, its impact on genetic diversity and genetic structure and its potential role in explaining the invasion process of U. pumila.Genetic analyses indicated widespread hybridization with native Ulmus rubra in naturalized U. pumila.

It is easily distinguished from other North American elms by its singly serrate leaf margins. Ulmus pumila is similar to U. Since the introduction of Siberian elm, Ulmus pumila L, into cultivation, much confusion has existed in the trade between this species and Ulmus parvifolia, the true Chinese elm. However, distinct vegetative, cultural, and aesthetic dif-ferences are apparent between these two Asiatic elms Ulmus pumila is an introduced species, widely planted and sometimes escaping. Successful escaped plants are often on disturbed sites such as abandoned fields and rights-of-way.
