摘　　要：１９９０年引人１１个种源的银合欢，在南亚热带云南景东育苗栽培试验，结果表明银合欢有较强的生态适应性。其中勐腊、元谋、元江种源生长较好，东爪硅Ｋ×１、Ｋ×３Ｃ显示了抗逆性强的杂交优势，为我国热带、南亚热带地区推广栽培银合欢提供了科学依据。There have been many reports published on the introduction and cultivation of Leucaena leucocephala(Lam.)de Wit,but there has been no the report on its ecoadapta-tion. In this paper,introduced L.leucocephala from 11 provenances were collected and cult-vated in Jingdong County,Yunnan Province in 1990.The results indicated that the ecoad-aptability of this tree species was comparatively high, and among them,Mengla,Yuanmou,Yuanjiang grew best,the east Pulau Java K×1,K×3C showed strong hybrid vigor. The study has provided scientific basis for popularizing the cultivation of L.leucocephala in the tropical and southern subtropical zones of our country.
