降香黄檀不同家系测定试验初报

Preliminary Study on Dalbergia odorifera T.chen Different Families Tests

通过对福建省华安县西陂国有林场降香黄檀不同家系的胸径、树高、平均冠幅以及冻害程度等指标的测定与分析,结果表明：降香黄檀不同家系间胸径和树高生长差异极显著,造林后1 a胸径为1.22-2.38 cm,树高为1.55-2.27 m;而冠幅生长差异不显著,平均冠幅为0.30-0.58 m。综合考虑胸径、树高和冻害3个因素初步判断,21、118、8、49、39、43、90、14、115、46、55、16、19等13个家系在福建华安表现较好。

By measuring the dbh,tree height,average crown diameter and freezing injury of Dalbergia odorifera T.chen different families in Xipi National Forest Farm of Hua＇an,the results showed that the breast height and tree height were significantly different in different families,dbh growth ranged from 1.22 cm to 2.38 cm,height ranged from 1.55m to 2.27 m one year after planting,but the crown diameter was not significant,ranged from 0.30m to 20.58 m.Considering three factors：dbh,tree height,and freezing injury,the 13 families of 21,118,8,49,39,43,90,14,115,46,55,16,19 were relatively good families in Hua＇an,Fujian.
