新优观赏花木高盆樱桃研究进展

The Research Progress of New Ornamental Flowering Tree Cerasus cerasoides

摘要:

高盆樱桃Cerasus cerasoides为蔷薇科樱属落叶乔木，是我国唯一冬季开花的野生樱花，综合利用价值高，开发和应用前景广阔。但因其自然更新能力差及人类的过度开发，导致该种野生资源急剧下降。综述高盆樱桃的生物学特性及分布、繁殖技术、光合特性和适应性、遗传多样性、林业与园林应用等方面的研究进展，对目前存在的资源保护与利用不足、繁育和栽培技术落后等问题，提出就地保护和异地保存相结合、利用现代生物技术与传统育种手段培育新品种、积极开展繁育栽培技术研究等未来发展方向。

Abstract:

Cerasus cerasoides, belonging to Rosaceae,is a deciduous tree and is the only species of wild Cerasus spp. in China which blooms in winter. It has great development and application prospect for the high comprehensive utilization value. However, the wild resources of this species has declined sharply, due to its poor natural renewal ability and human over-exploitation. In this paper, its biological characteristics and distribution, reproductive technique, photosynthetic characteristics and adaptability, genetic diversity, application of forestry and landscape are summarized. In view of the existing problems such as insufficient protection and utilization of resources, backward breeding and cultivation techniques, the future development directions such as the combination of in-situ conservation and ex-situ conservation, the use of modern biotechnology and traditional breeding methods to cultivate new varieties, and the active research on breeding and cultivation techniques are put forward.
