本文分析了不同毛泡桐种子的发芽状况并对其进行了聚类分析．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，利用聚类方法将其划分为四组，该结果为泡桐引种培育新品种奠定了基础．
In this paper, the germination of Paulownia tomentosa seeds was analyzed and clustered. The results showed that light treatment could improve germination rate and germination potential of Paulownia tomentosa seed, and storage at room temperature was not conducive to the maintenance of seed vigor. According to the difference of germination rate and germination potential of Paulownia tomentosa seed under different conditions, Four groups, the results for the introduction of Paulownia cultivate new varieties laid the foundation.
