Indented growth rings were found long ago to be experimentally induced in Miller by thin parallel axial scratching of the bark up to the vascular cambium with a sharp blade. Here, we show that when the bark and vascular cambium of . are wounded by wide and long parallel axial wounds ("windows") rather than by thin scratches, the induced indented growth rings become dramatically more indented. All ten trees that were wounded by long parallel "windows" responded with very strong growth (especially in the first two years) that resulted in the formation of very conspicuous, extremely indented growth rings in the wood formed in between the long and wide woundings. This is true for both the trunks that were wounded all around their circumference and those that were wounded only in part of their circumference. We also suggest further lines of research.
很久以前就发现，用锋利的刀片在米勒树的树皮上平行轴向轻轻刮擦直至维管形成层，可通过实验诱导出缩进的年轮。在此，我们表明，当米勒树的树皮和维管形成层受到宽而长的平行轴向伤口（“窗口”）而不是细划痕的伤害时，诱导出的缩进年轮会变得明显更缩进。所有十棵受到长平行“窗口”伤害的树都表现出非常强烈的生长（尤其是在头两年），这导致在长而宽的伤口之间形成的木材中形成非常明显、极其缩进的年轮。对于树干周围全部受伤的和仅部分圆周受伤的情况都是如此。我们还提出了进一步的研究方向。
