Juvenile to mature wood transition in one clone of populus deltoides implanted in buenos aires, argentine
The aim of this work was to determine the age at which the transition of the juvenile wood to the mature wood takes place, by means of the parameters: density, morphometry of fibers, and vessels in one poplar clone. Five 17-year-old Populus deltoides "Australia 129-60" trees were sampled f...

Five 17-year-old Populus deltoides "Australia 129-60" trees were sampled from a commercial plantation in Buenos Aires, Argentina. Samples were taken at 5 heights from the trunk: 0.3 m, 1.3 m, 4.2 m, 8.1 m and 15.9 m and the annual radial growth, wood density, morphometry of fibers and vessels, and cell wall area were measured.
