Abstract: The rejuvenation character of root-sprouts of Eucommia ulmoides was studied. The result shows that the juvenility of root-sprouts is similar to that of one-year-old seedlings of this tree species. This character could be kept up to the age of two years and then weaken evidently. Therefore it would be suggested that the effective range of ages for collecting soft cuttings of Eucommia ulmiodes should be either 1-year-old root sprouts or 1-year-old trees.
