| 摘 要： | 对25个美洲黑杨无性系单株材积、湿心材、通直度、尖削度、树皮厚度等性状进行了调查研究。方差分析结果显示,各性状差异极显著(Sig.0.01),存在广泛变异,重复力高(R0.58);表型相关和遗传相关分析表明,单株材积、湿心材材积、树皮材积、通直度、尖削度、不同高度直径间显著正相关;单株材积与树皮材积(r=0.992)、湿心材材积(r=0.596)呈线性相关。利用综合评定法评价无性系,当入选率为20%,初步选出624、609、616、629和623等5个无性系,入选无性系单株材积、地径和胸径遗传增益分别为30.49%、11.12%和15.60%。

| Abstract: | The present research focused on the property of a number of traits such as volume,wet heart wood,straightness degree,tapering grade,bark thickness of 25 Populus deltoides intraspecific crossing clones.Anova analysis showed that there exhibited an extremely significant differences(Sig.< 0.01) and high repeatability(R > 0.58) of respective traits among the tested clones.Phenotype and genetic correlation analysis further revealed that properties of volume,wet heart wood,bark thickness,straight degree,tapering ... |
