Microprojectile-mediated genetic transformation and regeneration of Chinese elm

Canadian Journal of Plant Science, 2003
A protocol for the genetic transformation and regeneration of Chinese elm ( Ulmus parvifolia Ja cq.) is reported. Cell suspension cultures were initiated from hypocotyls and were maintained on Murashige and Skoog (MS) basal semi-solid medium supplemented with varying concentrations of thiadiazuron (TDZ) and 1-naphthaleneacetic acid (NAA).

Chemical growth control of Chinese elm trees

California Agriculture, 1967
A 2500 ppm MH30T spray applied in July appeared to give satisfactory growth control in Chinese elms the following year, at least up to the later part of June—and with less detrimental effects to the trees than other sprays tried.

Growth control of Chinese elm with inhibitor sprays

California Agriculture, 1983
Spray applications of growth inhibitors to the foliage of ornamental plants have been known for many years to be effective. Sprays have been used to some extent, but possible hazards from spray drift to nontarget ornamental plants have led to the ...

Exploring Travel Information Adoption on Social Media in the Chinese Context: An Extended ELM Model with Users’ Social Presence

International Journal of Marketing and Social Policy, 2017
Travel information adoption on social media has been acknowledged to be a complex process of both central route (argument quality) and peripheral route (source credibility). However, less effort has been placed on what triggers the persuasive communication process and how it varies. This study aims to examine the impact of technical adequacy (perceived
