Sammanfattning
Experiments within genetic tree research are often carried out on cultivated saplings of hybrid aspen (Populus tremula x tremuloides). The objective of the present study was to develop a tensile test method for small green samples from saplings, and to compare mechanical properties of juvenile hybrid aspen and European aspen (Populus tremula). Small specimens from samples of the two species were manufactured using a sleigh microtome and successfuly tested. Strain was determined by digital speckle photography (DSP). Results showed significantly lower values for the hybrid aspen in both tensile strength and Young’s modulus parallel to grain. Differences in mechanical properties correlated with lower density in the hybrid than in the juvenile European aspen saplings
