摘　　要：北美红杉在云南引种栽培近30年,生长发育正常,与原产地比较相近,保持了速生特性和较强的抗逆性。引进的北美红杉不同种源、不同无性系,在云南不同生态环境生长有显著差异;在幼龄期表现较好的有SYA4s、SYA6s等6个优良种源和无性系,分别适应云南省的纬度范围为北纬22°59′～26°52′,海拔高度为1300～2400m的不同海拔、不同气候带、不同生态环境。还有少数耐寒种源和无性系,在海拔3200～3500m的高寒山地也能生长。该项研究对促进北美红杉在云南发展造林将起到积极推进作用。Sequoia sempervirens has been introduced to Yunnan province for 30 years, the growth performance was similar to its originated place, and the characteristics of fast growing and stress resistance were maintained. The results of introduction experiment in Yunnan province showed that there were difference of growth performance between different provenances and clones under different ecological environment. Six provenances and clones such as SYA_4s and SYA_6s, respectively suitable for north latitude 22°59′～26°52′, and elevation of 1 300～2 400 m. Some cold-resistant provenances and clones could stand the condition of 3 200～3 500 m. The introduction experiment and research of Sequoia sempervievens would promote the development of reforestation of Yunnan province.
