摘要: 山定子隶属于蔷薇科苹果亚科苹果属苹果亚属山定子组山定子系, 在我国主要分布于黄河以北地区。山定子野生资源分布范围广,在长期的进化和演变过程中,形成了丰富多样的类型,具有极大的研究利用价值。目前已发现抗寒、抗旱、耐瘠薄、耐盐碱和耐涝、耐阴湿等野生山定子的特异资源,而对其利用研究主要集中在抗寒育种、多抗性砧木、加工及景观等方面,并已选出了可用于生产的品种和砧木优系及较有前途的景观类型,同时开发出了果实等深加工产品。今后应继续加强对山定子野生资源的保护和利用研究,利用常规技术结合现代分子生物学手段,建立一套可操作的特异性状评价体系,提高资源利用效率,并加强功能性成分的鉴定、分离及作用机制的研究,为野生山定子产业化综开发利用奠定基础。

Abstract: The wild germplasm resources of Malus baccata ( L.) Borkh distribute widely, and have diverse types, which showed great value of research and utilization. Natural distribution and taxonomic status of wild Malus baccata ( L.) Borkh in China were summarized, the result showed that the wild germplasm resources of Malus baccata ( L.) Borkh mainly distribute in the area north of Yellow River, distribute specifically in Northeast and Inner Mongolia, Shanxi, Hebei, Henan, Shaanxi, Gansu, Tibet and Yunnan in china; Malus baccata ( L.) Borkh belongs to Rosacea Maloiedae Malus. Mill. Subgen. Mauls Sect. Gymnomeles. Koehne Ser.Baccata(Rehd.)Rehd.Now some specific resources of wild Malus baccata ( L.) Borkh who are types of cold resistance, drought resistance, barren, resistance to alkali and waterlogging were found recently. At present the study on utilization of Malus baccata ( L.) Borkh mainly concentrated on breeding of cold resistance,multi- resistant rootstock,processing and landscape utilization, it were selected that the superior lines of varieties and rootstock which can be used for the production and the promising landscape types, deep processing products were exploited. In the future, we should continue to strengthen the research on protection and utilization of the wild resources of Malus baccata ( L.) Borkh, establish a set of operational evaluation system for specific characters based on the conventional techniques and modern molecular biology methods, improve the resource utilization efficiency, and strengthen the study on identification,separation and action mechanism of functional components for laying the foundation of the comprehensive exploitation of the wild Malus baccata ( L.) Borkh.
