摘　　要：The overwinter terminal buds of Paulownia elongata seedlings,tranplanted in February or before the mid of March in Zhengzhou of Henan Province were not able to flush due to water lost from the buds,and the bud died from the dry within 15～20 days after transplantation. Supplementary measures would be used to postpone flushing of terminal buds without influencing survival of the seedlings. By burying the seedlings in soil to the last ten days of March or the first ten days of April,the flush rate of the buds was able to be promoted. The rate of height of stem extension by terminal buds in height of main stem was 96.71% in the same year,and the rate of trunk straight by main stem extension of terminal buds was 100%. The figure of main stem extension process of terminal buds of Paulownia elongata seedling trees was given in this paper for the first time.The overwinter terminal buds of Paulownia elongata seedlings, tranplanted in February or before the mid of March in Zhengzhou of Henan Province were not able to flush due to water lost from the buds, and the bud died from the dry within 15 - 20 days after transplantation.
