史密斯桉种源遗传变异与稳定性分析

Analysis on Genetic Variation and Stability in Provenance of Eucalyptus smithii

    摘要
  • 摘要: 史密斯桉种源试验结果表明:树高、胸径、材积种源间变异相对较小,而种源内个体间的变异较为丰富.史密斯桉生长量比直干桉和蓝桉更大.树高种源间、地点间、地点和种源间交互作用都达到显著水平,进行种源、地点选择是有效的.在史密斯桉的推广中种源和地点间交互作用值得注意.史密斯桉树高、胸径、材积3个性状受一定的遗传控制。

     

    Abstract: The provenance experiment on Eucalyptus smithii shows that height,DBH,volume have little variation in provenance,and great variation in individuals.The growth is superior to Eucalyptus globules and Eucalyptus maidenii.There is significant difference in the interaction of provenance×site,site and provenance.Provenance selection as well as site selection is effective and the interaction of provenance×site is worth paying attention to.Height,DBH and volume is controlled by some extend genetics.
