本文分析了不同地区毛泡桐种子的发芽状况并对其进行了系统聚类分析。结果表明，光照处理有利于提高毛泡桐种子的发芽率和发芽势，室温贮藏不利于种子活力的长期保持。根据不同条件下毛泡桐种子发芽率和发芽势的差别，利用系统聚类方法将其划分为四组，该结果为泡桐引种和培养新品种等奠定了基础 In this paper, the germination of Paulownia tomentosa seed in different areas was analyzed and systematically clustered. The results showed that light treatment was beneficial to improve the germination rate and germination energy of Paulownia seedlings. Storage at room temperature was not conducive to the long-term preservation of seed vigor. According to the difference of germination rate and germination potential of Paulownia tomentosa seed under different conditions, it was divided into four groups by using the method of cluster analysis, which laid the foundation for the introduction of Paulownia and the cultivation of new varieties
