摘要：
The mechanical characteristics of the strengthening tissue of young axes of Aristolochia macrophylla were studied in successive loading-unloading cycles in tension. Elastic, viscoelastic and plastic deformations could be distinguished. After the first cycle, the material was in a state different from its original state, to which it returned only partially and/or slowly. Internal 'microstructural' prestresses are considered as an explanation for the mechanical behaviour seen in Aristolochia macrophylla and several other plants.
