摘　　要：对以种子引自美国、苗圃培育的1年生大花四照花(Cornus florida)采用有序样本聚类分析法进行生长阶段划分,结果表明,大花四照花在浙江苗期生长良好,可划分为3个生长阶段:生长初期为4月1日至5月31日,生长盛期为6月1日至8月15日,生长后期为8月16日至11月16日。Seeds of Comus florida were imported from the USA and sowed in 2005. Germination was found in 2007 and seedlings were transplanted at orchard of Zhcjiang Forestry Academy. Observations were implemented on growth of the seedlings, and growth period was divided by sequential sample cluster analysis. The result demonstrated that growth of l-year seedling could be divided into three stages, like early growth stage （April 1-May 31 ）, rapid growth stage （June 1- August 15）, late growth stage（August 16-November 16）.
