| 摘 要： | 通过对44株日×兴杂种落叶松F1代个体的生长性状、木材性状调查结果进行变异分析发现,杂种群体中的生长指标、材性均存在较大变异,其中材积变异系数达25.69%,管胞长度、宽度变异系数为11.67%、17.5%,管胞长/宽变异系数为19.45%。相关分析结果表明,日×兴F1代群体树高与胸径显著相关,树高、胸径均与材积极显著相关,冠幅与材积显著相关。

| Abstract: | Variability of individual growth traits,wood properties of 44 trees （Larix kaempferi × Larix gemlinii Hybrid Larch F1 generation） were analyzed. Result shows that： the growth and wood properties of hybrid population all have a large variation,among which the volume coefficient of variation being 25.69% ;coefficient of variation of tracheid length, tracheid width are 11.67% , 17.5% ; coefficient of variation of tracheid length divided by tracheid width are 19.45%. The correlation analysis on L. kaempferi × L. gemlinii F1 generation shows that ：tree height are significantly relate to DBH ;tree height ＆ DBH are significantly relate to timber volume;crown are significantly relate to timber volume. |
