摘　　要：本文对2014至2019年间洛阳农林科学院营建的13片楸树无性系和家系试验林的树高、胸径进行系统观测和分析。结果表明;参试楸树第2、3、4年树高生长活跃,增速明显,其中第3年树高树高增长量最大;第2、3、4、5年胸径增长活跃,其中第2年胸径增长量最大。In this paper, a systematic observation and analysis was made on the tree height and DBH of 13 plantations of Catalpa bungei clones and cultivars. The results showed that the height growth of the tested trees was active and significant in the 2nd, 3rd and 4th years with the highest height increment in the 3rd year;the DBH growth was active in the 2nd, 3rd, 4th and 5th years with the highest DBH increment in the 2nd year.
