Confirming Replant Failure in Some Species of Trees for Landscaping

Abstract

To confirm replant failure in trees for landscaping, five species, Prunus yedoensis, P. mume, Acer palmatum, Daphne odora and Euonymus japonicus, which have been said to show this phenomenon, were used in this experiment.
Total shoot growth in all kinds of trees grown in old soil, which have been used to grow the same species, was decreased drastically comparing with that in virgin soil. Dry weight of the trees was about 70% less in A. palmatum and D. odora, 30% less inE. japonicus and slightly decreased in P. yedoensis, but not in P. mume.
Degree of depression was larger in top than in root of all kinds of trees studied.
