| 摘 要： | 以18个3 a生麻栎(Quercus acutissima)无性系为研究对象,对其树高、地径、材积、高径比、通直度、分枝数等性状进行遗传力测定、相关分析和通径分析.结果表明:无性系间各性状均存在极显著差异,各性状受中到强度遗传控制.树高与材积、高径比,材积与高径比,通直度与树高、材积均呈极显著的正相关,分枝数与通直度呈负相关.通径分析表明,树高、地径、高径比、通直度和分枝数5个指标可描述单株材积变异的93.66%.

| Abstract: | Correlation,path analysis,inheritance and variation among tree height,volume,base diameter(DBase),height/ base diameter(H/DBase),branch number and straightness of eighteen 3-year-old Quercus acutissima clones were analyzed.Results showed that there was significant difference among traits,and they were genetically controlled in moderate degree.Correlations between height and volume and H/DBase,volume and H/DBase,straightness and height and volume were significant,and correlations between branch and straightness of clones was negative,respectively.Five traits(height,DBase,H/DBase,branch number and straightness) explained 93.66% of variation of the individual tree volume. |
