Grafting is a widely used technique for asexual plant reproduction, especially in agriculture and forestry. This procedure is used to shorten the seedling period, improve the structure of scion branches, and help plants adapt to difficult environments. Although grafting has numerous benefits, several obstacles remain to be overcome. The connection between scion and rootstock is regulated by various factors, including phytohormones and molecular mechanisms, which are crucial for graft healing. This review provides an overview of recent advances in the field of grafting, with a specific focus on the factors and regulatory pathways that influence graft healing. The ultimate goal is to aid understanding of how to achieve successful grafting between plants and create desirable grafting chimeras. We provide an overview of the latest developments in plant grafting, covering aspects related to morphology, physiology, and molecular biology. We also discuss research directions in polyploid breeding and long-distance transfer of small molecules in grafted plants.
嫁接是一种广泛应用于无性植物繁殖的技术，尤其在农业和林业中。这个过程用于缩短苗期、改善接穗枝条的结构，并帮助植物适应恶劣环境。尽管嫁接有诸多益处，但仍有几个障碍有待克服。接穗和砧木之间的连接受多种因素调控，包括植物激素和分子机制，这些对嫁接愈合至关重要。本综述概述了嫁接领域的最新进展，特别关注影响嫁接愈合的因素和调控途径。最终目标是有助于理解如何实现植物间的成功嫁接并创造理想的嫁接嵌合体。我们概述了植物嫁接的最新进展，涵盖形态学、生理学和分子生物学等相关方面。我们还讨论了多倍体育种以及嫁接植物中小分子长距离转运的研究方向。
