| 中文摘要: |
| 云南松作为我国西南地区造林和用材的主要树种，近年来由于受到粗放经营管理及不良遗传效应的影响，林分的衰退问题已经日益严重。为此，从遗传变异、苗木生长影响因素、种质资源等方面综述了云南松近年来的研究进展。针对其林分质量衰退问题，建议采用分子生物、基因工程等生物技术，结合生态学方法，培育优良种苗，改造低效林分等方法或措施，以提高林分质量和整体效益。 |
| 英文摘要: |
| Pinus yunnanensis is the main tree species for afforestation and timber in southwest China. Due to the influence of extensive management and genetic effects, the decline of Pinus yunnanensis stand has become increasingly serious. Therefore, the research progress of Pinus yunnanensis in recent years was reviewed from the aspects of genetic variation, influencing factors of seedling growth and germplasm resources. In view of stand quality decline of Pinus yunnanensis, this paper suggested that molecular biology, genetic engineering and other biotechnology, combined with ecological methods should be used to cultivate excellent seedlings and transform inefficient stands, so as to provide theoretical and practical basis for improving stand quality and overall benefit of Pinus yunnanensis. |
