| 摘 要： | 对10年生的31个泡桐无性系的生长状况进行了分析，结果表明，不同无性系间性状表现差异较大，胸径的遗传力较高，可以作为选择的主导性状，主干材积的潜在改良能力最大，相关分析表明，多数性状间有显著相关关系，在选育时应统筹兼顾，丛枝病发病程度在无性系间差异显著，在本试验条件下，生长性状优良、发病率较低的无性系为8508－2，毛杂等。

| Abstract: | Growth characters analysis of 31 10-year-old paulownia clones shows that significant differences exist between different clones that the diameter of breast height may act as the dominant character for selection because of its higher genetic ability, and that the stem volume has the greatest potential for improvement. Correlation analysis indicates that many characters are closely correlated and must be considered during selection. The degree of withches'-broom are quite different. The clones 8508-2、Mao-za are the best clones concerning growth characters and witches'-broom occurrence frequency. |
