healthy state. Most of them belong to different discrete local populations.
Populus tremula L. was propagated in proliferation Aspen Culture Medium; they required subculture every
3 months. The purpose of this study was, therefore, to select a medium which allows the maintenance of 32
clones for a period longer than 3 months without subculture and to observe the behavior of those clones in 15
different culture medium compositions. Seven nodal cutting… More >
