| Abstract: | The growth and morphological characteristics of 25 species of poplar were investigated. The cuttings were cultivated in Hoagland Nutrient Solution, which was made with sodium chloride (NaCl) solutions of concentration of 1.00, 3.00, 4.00, 5.00, 6.00, and 8.00 g/L, respectively. Under such salt stress, the new branch length and biomass accumulation of cuttings decreased as the salt concentration increased. The root/shoot ratio of most of species showed an escalation and then reduction tendency. Under low con... |
