摘要翻译：
为了应对环境的限制，树木能够通过控制新形成的木材层中的应力水平来重新定位它们的轴线。被子植物和裸子植物演化成两种截然不同的机制：前者在倾斜轴的上侧产生一种具有较大拉伸预应力的木材，后者在倾斜轴的下侧产生一种具有较大压缩预应力的木材。在这两种情况下，这一应力水平与相对侧的应力水平之间的差异，在轻张力下，产生轴的弯曲。然而，有时在被子植物的对侧测量压缩光值。通过对板栗和马尼的旧数据和杨树的新数据的分析，本研究表明这些值不是测量人工制品。这表明在对向木材中产生光压应力有助于改善再定向机构的性能。

英文摘要：
In order to face environmental constraints, trees are able to re-orient their axes by controlling the stress level in the newly formed wood layers. Angiosperms and gymnosperms evolved into two distinct mechanisms: the former produce a wood with large tension pre-stress on the upper side of the tilted axis, while the latter produce a wood with large compression pre-stress on the lower side. In both cases, the difference between this stress level and that of the opposite side, in light tension, generates the bending of the axis. However, light values of compression were sometimes measured in the opposite side of angiosperms. By analysing old data on chestnut and mani and new data on poplar, this study shows that these values were not measurement artefacts. This reveals that generating light compression stress in opposite wood contributes to improve the performance of the re-orientation mechanism.
