【摘要】 根据群体遗传结构模式，将毛泡桐×白花泡桐和毛泡桐×兰考泡桐Ｆ１ 无性系的年生长进程划分为早中后期。通过用Ｌｏｇｉｓｔｉｃ 曲线对各无性系的年生长的模拟，估测了各无性系生长速率的最大点和速生期天数。根据速生期对早中后３ 个时期的覆盖程度，对不同无性系的生长形式作了分析。以正交多项式模拟生长曲线，检验了苗高、地径增长曲线的差异显著性，结果显示：无性系间苗高、地径生长曲线在阶段上存在显著差异。更多还原

【Abstract】 On the basis of variation patterns of genetic structure of paulownia,the annual growth process was classed into early,intermediate and later three periods in paulownia fortunei tomentosa ×paulownia fortunei F 1 clones and paulownia fortunei tomentosa×paulowmia fortunei elongata F 1 clones.The properties of annual growth of various clones were stimulated by logistic curve,and the maximum points of growth rate per day and the lengths of fast-growing stage were also estimated.on the basis of the degrees in which the early,intermediate and later three periods were covered by the fast-growing stages,the growth patterns of different clones were analysed.The clonal growth curves were approached by cross cut polynomiad and the coefficients β 0,β 1,β 2 which made up the growth curves were tested.The results indicated that the differences of the growth curves of hight and diameter were significant only in stage.更多还原
