【摘要】 园林植物在人类日常生活中发挥着不可或缺的作用。我国园林植物种质资源丰富多样，各科研院所围绕园林植物进行了多方面研究和探索，取得了一系列成果。但针对园林植物的系统调查和研究起步则相对较晚，对园林植物种质资源的相关研究还相对分散，缺乏系统性。基于此，从就地保护、异地保存、野外回归3个方面综述了我国园林植物种质资源的保存途径，从新优品种创制和优良观赏性状调控、遗传和进化、种子研究等方面分析了园林植物种质资源研究现状。此外，还就继续加强种质资源收集和保存、球根类植物种质资源扩繁和利用、园林植物利用和管理方式创新等问题进行了展望，以期为我国园林植物种质资源进一步研究、高效保存和综合利用等提供参考。更多还原

【Abstract】 Landscape plants play an indispensable role in our daily life. The germplasm resources of landscape plants are rich and diverse in China. Research institutes and universities have made great progress in the research and exploration on landscape plants in many aspects. However, the systematic investigation and research on landscape plants started relatively late, and the researches on germplasm resources of landscape plants are not systematic enough. Based on this, we summarized the conservation methods for germplasm resources of landscape plant, including situ conservation, remote conservation and field return. We analyzed the research status of landscape plant germplasm resources from the perspectives of the creation of new varieties, regulation of fine ornamental traits, genetics and evolution, and seed research. Some problems such as the continuous collection and conservation of germplasm resources, the propagation and utilization of bulbous plant germplasm resources, and the innovation of utilization and management of landscape plants were prospected to provide references for further research, conservation and utilization of landscape plant germplasm resources.更多还原
