摘　　要：为了探讨产自南美洲的巴拉那松是否能在云南引种成功,于2001年开始在昆明市进行巴拉那松引种育苗试验,并进行发芽率测试、生长性状观察与物候期观察。结果表明,(1)在较好的管理措施下,巴拉那松出苗活率高达90%;(2)育苗后百日苗等级高,达同属苗木Ⅰ级水平;(3)自然播种或播种后移栽,苗木生长均良好,但移栽后效果更佳。20cm×21cm盆移栽,年均高增长44.8cm,平均地径增加1.2cm。20cm×30cm盆移栽,年均高增长48.00cm,地径增加1.1cm。自然播种,年均高增长22.1cm,地径增加0.44cm;(4)引种后的苗木具有良好的抗逆性和再生能力,适应在云南开展区域试验造林。In order to study whether Araucaria angustifolia,which grow in Brazil originally,could be successfully introduced into Yunnan Province,an introduction trail was done in Kunming from 2001,and relevant observations and researches were conducted from perspectives of germination test,growth traits,phenology,and etc. The results showed that：（ 1） Araucaria angustifolia grow well and fast in Yunnan Province under well management,and seedling survival rate achieved to 90%;（ 2） the quality of its seedling meet the Ⅰ-class seedling standard after100 days;（ 3） the seedling could grow well after naturally seeding or transplant,while better after transplant,the annual average height increase and ground diameter reached to 44. 8cm and 1. 2 cm in pot with the size of 20cm×21cm,that of 20cm×21cm pot reached to 48. 00 cm and 1. 1 cm,the annual average height increase and ground diameter under natural seeding reached to 22. 1cm and 0. 44 cm respectively;（ 4） the seedling have good cold tolerance for cold temperature with good regeneration capability,and regional plantation test can be implemented in Yunnan Province.
