Current-year seedlings of Oplopanax elatus can survive completely and grow n ormally on sites within their natural distributing area. The seedling height ten ded to increase quickly; root collar growth showed a slow increase; main root le ngth manifested almost no difference between years; fresh weight of seedling dem onstrated an upward trend. Two or three years old seedlings could survive comple tely on sites with environment conditions similar to their natural distributing area, but the growth of two-year-old seedling was frustrated in the first year a fter transplantation. The seedlings transplanted to natural distributing area gr ew slower than those cultivated in greenhouse.
