Abstract: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.
Keywords:Catalpa bungei  natural variation  improved variety selection  regression analy-sis
