摘　　要：为探讨面包树在贵州热区的适应性表现,创新种质资源,增加特色优新物种,对2008年从广西南宁引种的太平洋面包树和重庆南川面包树一年生种苗分别在望谟和兴义进行了野外栽培试验。结果表明:太平洋面包树不能安全越冬,南川面包树在两地的苗木定植成活率为96.8%～97.5%,能安全越冬,生长良好,树高、茎粗、冠幅、1级分枝、2级分枝等生长量比引种苗分别增加4.3倍、6.4倍、11.3倍×7.0倍、7.8倍和39倍。南川面包树引种成功,对贵州热区生态建设、特色农业开发等具有重要的科学和实践意义。In order to explore the adaptive performance, innovate germplasm resources and explore characteristic excellent new species, field cultivation tests were conducted in Wangmo and Xingyi using 1-year-old seedlings of pacific breadfruit tree and Nanchuan breadfruit tree introduced from Guangxi and Chongqing in 2008. The results showed that pacific bread tree could not live through the winter. Nanchuan bread tree grew well in winter with seedling planting survival rate 96.8%-97.5%, the tree height, stem diameter, crown diameter, first branch number, second branch number were 4.3, 6.4, 11.3 7.0, 7.8 and 39 times that of introduced seedlings respectively. The successful introduction of Nanchuan bread tree was of significant scientific and practical meaning to the hotspot ecological construction and characteristic agricultural development.
