Responses of Populus deltoides × Populus nigra ( Populus × euramericana ) clone I - 214 to high zinc concentrations

• We hypothesized that poplar can be useful for the extraction of zinc (Zn) from contaminated soils and water. However, the physiological response and the base of tolerance of poplar plants to this heavy metal are little known. • Plants of Populus deltoides × P . nigra ( P. × euramericana ) I-214 clone were grown in glasshouse and treated with three different Zn concentrations (1, 100 and 1000 ...

Somatic Embryogenesis of Populus deltoides

Node, internode, and leaf explants of Populus deltoides Bartr. ex Marsh. × Populus deltoides Bartr. ex Marsh. hybrid poplar clone (89 M 066) tissue culture regenerated plantlets were used for direct and indirect somatic embryogenesis. Direct somatic embryos were differentiated on node, internode and leaf explants on Murashige and Skoog basal medium (MS) supplemented with N 6 -Benzyladenine (BA)...

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...
