| 摘 要： | 对河南郏县侧柏全分布区种源试验林66个种源19年生植株的性状分析表明,主干生长、冠幅、分枝角和树形指标在种源问差异显著,主干生长、冠幅、分枝角的种源遗传率均达到0.6以上.种源各调查指标与经度、纬度和海拔无明显相关,呈随机地理变异特点,表现与苗期性状不同的地理变异.主成分分析表明主干生长、树冠和形质指标对侧柏种源性状变异的影响较大.按主干生长和树冠可把供试种源聚为4个类群,但类群内无明显地理集群特点. |

| Abstract: | Based on a wide range provenance trial with 66 seed sources,located in distribution area of the species,in Jiaxian county,Henan province,China,nine plant traits were analysed.Results showed that significant differences were found in many traits between provenances,especially in stem height,ground diameter,crown,branching angle and tree form index(tree height against the broadest crown height).The general estimated provenance heritabilities of the traits listed before were over 0.6.There were no significant ... |
