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%。西北林学院学报22卷第6期董玉峰等麻栎无性系苗期性状的研究
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 3yearold 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.
