| 摘要: |
| 收集广东、海南、广西及福建地区 10 个降香黄檀（Dalbergia odorifera）种子并培育，比较分 析不同家系的早期生长表现。结果表明：不同家系间树高、地径、保存率存在极显著差异；综合生长指 标以肇庆广宁中学、广州华农林学院，海南乐东抱由林业局和海南乐东抱由苗圃场共4 个家系表现最好， 可作为降香黄檀采种育苗或无性繁殖的材料加以重点研究；树高与海拔存在显著正相关，说明一定范围 内较高海拔有利于树高的生长；年均降雨量与地径、保存率均存在显著正相关，说明一定范围内年均降 雨量越大，越有利于促进降香黄檀径的增长及提高苗木保存率。 |

| Abstract: |
| The early plantation stage growth status of 10 families of Dalbergia odorifera from Guangdong,Hainan,Guangxi and Fujian, was studied in this paper. The result showed: There was significant differences of the tree height, grond diameter and survival rate among the families. The GuangNing middle school of Zhaoqing, College of Forestry in South China Agricultural University, BaoYou Forestry Bureau and BaoYou nursery garden could be the material of collect seeds and nursery and reproduce asexually of D.odorifera for the superior growth traits. Correlation analysis between growth performance and ecological and geographic factors revealed significantly positive correlation.There annual rainfall demonstrated significantly positive correlation with ground diameter and survival rate. |
