Cutting-induced adventitious root (AR) formation is crucial for vegetative propagation, a key method that produces plants identical to parent. However, many woody plants pose challenges for vegetative propagation due to difficulties in AR formation. Hormones play important roles during AR formation, with auxin serving as the key regulator and interacting with other hormones. In this review, we summarize the molecular events and hormone functions involved in AR formation in woody plants. A deeper understanding of these processes could enhance the design and manipulation of techniques to improve vegetative propagation in woody plants, ultimately leading to greater economic benefits.
扦插诱导不定根（AR）形成对于营养繁殖至关重要，营养繁殖是一种培育与亲本相同植株的关键方法。然而，许多木本植物由于不定根形成困难，给营养繁殖带来了挑战。激素在不定根形成过程中发挥着重要作用，生长素作为关键调节因子，并与其他激素相互作用。在本综述中，我们总结了木本植物不定根形成过程中涉及的分子事件和激素功能。对这些过程的更深入理解可以改进木本植物营养繁殖技术的设计与操作，最终带来更大的经济效益。
