| 摘 要： | 通过对澳大利亚、广州新银合欢原种以及从广州引入宁南和会东栽培繁殖并扩繁到本区不同地点的后代采种进行种源比较试验，其结果表明：在苗期本地种源生长优于原种地，但造林后随着幼树生长，广州种源逐步赶上并超过除宁南种源外的其他种源。而宁南种源是所有参试种源中的最佳种源。建议今后可将宁南县划为金沙江干热河谷及其类似地区的新银合欢优良种子调拨区。

| Abstract: | In this paper,researchers made a comparative provenance test between native Leucaena leucocephala from Australia or Guangzhou and seeds collected from the offspring of which had been introduce from Guangzhou to Ningnan and Huidong and expanded reproduction in these areas.The results showed that the growth of local provenance was better than that of origin in seedling stage,but the growth of Guangzhou provenance overtook other provenances except Ningnan provenance after afforesting,and the Ningnan provenance... |
