With few exceptions, terrestrial plants are anchored to substrates by roots that experience bending and twisting forces resulting from gravity- and wind-induced forces. Mechanical failure occurs when these forces exceed the flexural or torsional tolerance limits of stems or roots, or when roots are dislodged from their substrate. The emphasis of this review is on the general principles of anchorage, how the mechanical failure of root anchorage can be averted, and recommendations for future research.
除了少数例外，陆生植物的根系扎根于基质中，这些根系会受到由重力和风力引起的弯曲和扭转力的影响。当这些力超过茎或根的弯曲或扭转耐受极限，或者当根系从基质中松动时，就会发生机械故障。本篇综述的重点是锚固的一般原理，如何避免根系锚固的机械故障，以及对未来研究的建议。
