摘　　要：果核是包被种胚的外部结构,在果实发育过程中,对种子起到保护作用,并对果肉提供支撑。果核的主要成分为木质素和纤维素。本综述阐释了果核退化的果实类型以及果核退化对果树育种的影响,包括无核果实和核果类果树裂核现象,并通过对木质素的合成途径及其在合成过程中的动态分布、差异蛋白分析、相关酶和激素进行研究,并对影响木质素合成物质的糖类和酚类物质的代谢状况,以及果核退化相关的基因调控果核发育的研究等多方面进行综述,阐释果树果核退化的机制,认识木质素对果核退化的影响,为果树的果实无核化育种提供理论依据,并对防止果核裂核提供理论指导。The nucleus is the external structure of the coated embryo, which protects the seed during fruit development and provides support for the pulp. The main components of the kernel are lignin and cellulose. This review explained the fruit types of fruit nuclear degradation and the effects of nuclear degradation on fruit tree breeding, including the nucleation of seedless fruit and fruit tree. Through the synthesis of lignin and its dynamic distribution in the synthesis process, differential protein analysis, related enzymes and hormones to investigate the metabolism of carbohydrate and phenolic substances that affect lignin synthesis. This review summarized the research on the nuclear regulation of nuclear regulation related to nuclear degradation and attempts to elucidate the mechanism of fruit tree degradation and the effect of lignin on nuclear degradation. This review provided a theoretical basis for the sterilization of fruit trees, and also provided theoretical guidance for preventing nuclear from cracking.
