Response of Populus × canescens (Populus tremula × alba) to high concentration of NaCl stress
Journal of Forestry Research, 2006Populux × canescens was cultivated on solid substrate and treated by salt (150 mM NaCl). The growth parameters including new leaf formation, height increment, diameter at the base increment, fresh and dry mass of leaf, stem, coarse root, and fine root were determined. The nutrient elements in leaves of samples under salt stress and the control, and the

Propagation and DNA Markers Characterization of Populus Tremula L. and Populus Alba L.
2003The genus Populus is a part of the family Salicaceae which appeared in the early Cretaceous and expanded in the Tertiary, presently consisting of about 40 species of temperate and cold regions of the Northern Hemisphere, America, Europe and Asia, but also reaching Eastern Africa (Tanzania, Uganda). Populus spp.

Expansins are important plant cell wall proteins. They can loosen and soften the cell walls and lead to wall extension and cell expansion. To investigate their role in wood formation and fiber elongation, the PagEXPA1 that highly expressed in cell differentiation and expansion tissues was cloned from 84K poplar (Populus alba × P. glandulosa).
