Kiwifruit, with its unique flavor, nutritional value, and economic benefits, has gained significant attention in agriculture production. Kiwifruit plants have traditionally been propagated without grafting, but recently, grafting has become a more common practice. A new and complex disease called Kiwifruit Vine Decline Syndrome (KVDS) has emerged in different kiwifruit-growing areas. The syndrome was first recognized in Italy, although similar symptoms had been observed in New Zealand during the 1990s before subsequently spreading worldwide. While kiwifruit was not initially grafted in commercial orchards, the expansion of cultivation into regions with heavy soils or other challenging environmental conditions may make grafting selected kiwifruit cultivars onto KVDS-resistant or -tolerant rootstocks essential for the future of this crop. Grafting is a common horticultural practice, widely used to propagate several commercially important fruit crops, including kiwifruits, apples, grapes, citrus, peaches, apricots, and vegetables. Grafting methods and genetic compatibility have a crucial impact on fruit quality, yield, environmental adaptability, and disease resistance. Achieving successful compatibility involves a series of steps. During grafting, some scion/rootstock combinations exhibit poor graft compatibility, preventing the formation of a successful graft union. Identifying symptoms of graft incompatibility can be challenging, as they are not always evident in the first year after grafting. The causes of graft incompatibility are still largely unknown, especially in the case of kiwifruit. This review aims to examine the mechanisms of graft compatibility and incompatibility across different fruit crops. This review's goal is to identify potential markers and techniques that could enhance grafting success and boost the commercial production of kiwifruit.
猕猴桃凭借其独特的风味、营养价值和经济效益，在农业生产中受到了广泛关注。传统上，猕猴桃植株是通过非嫁接方式繁殖的，但近来，嫁接已成为更普遍的做法。一种名为猕猴桃藤蔓衰退综合征（KVDS）的新型复杂病害已在不同的猕猴桃种植区出现。该综合征最初在意大利被发现，尽管在20世纪90年代新西兰就已观察到类似症状，随后蔓延至全球。虽然猕猴桃最初在商业果园中未进行嫁接，但随着种植向土壤厚重或其他环境条件具有挑战性的地区扩展，将选定的猕猴桃品种嫁接到抗KVDS或耐KVDS的砧木上可能对该作物的未来至关重要。嫁接是一种常见的园艺操作，广泛用于繁殖多种具有商业重要性的水果作物，包括猕猴桃、苹果、葡萄、柑橘、桃子、杏子以及蔬菜。嫁接方法和遗传相容性对果实品质、产量、环境适应性和抗病性有着至关重要的影响。实现成功的相容性需要一系列步骤。在嫁接过程中，一些接穗/砧木组合表现出较差的嫁接相容性，无法形成成功的嫁接愈合。识别嫁接不相容的症状可能具有挑战性，因为它们在嫁接后的第一年并不总是明显的。嫁接不相容的原因在很大程度上仍然未知，尤其是在猕猴桃的情况下。本综述旨在研究不同水果作物中嫁接相容性和不相容性的机制。本综述的目标是确定能够提高嫁接成功率并促进猕猴桃商业生产的潜在标记和技术。
