The results indicated that there existed significant differences in growth rate and wood quality among the provenances. A classical clinal variation pattern responding to the latitude of seed sources was found for DBH, height, individual volume and stem straightness, and water and heat resources of seed sources were the main climatic factors which caused the variation.

结果表明：马尾松生长、形质和木材基本密度皆存在显著的种源差异，种源胸径、树高和材积生长及树干通直度呈典型的纬向倾群变异模式，这种变异主要是由其产地水热资源条件差异引起的。
