摘要
对楸树中７种与生长相关的变异因子进行了数量化分析，得出树高、胸径、单株立木材积的主要因子与生长的相关关系，并建立了线性回归方程。提出了良种这样及早期测定的形质性状标准。
Seven variation factors being bound up with the growth of Catalpa bungei C.A.Mey. were quantitatively analysed.The relations between the growth and the major factorsof tree height,D.B.H. and single-tree standing volume were obtained. The line regressionequations were established.The standard of morphological character of improved varietyselection and early determination was put forward.
