Tensile force tests on the resistance of tree root system are performed on seven kinds of tree classified by the pot of root. Small roots, 1 to 10mm in diameter, sampled from living trees, are Crytomeria japonica, Pinus densiflora, Quercus acutissima, Magnolia kobus, Firmiana simplex, Carpinus tschonoskii and Zelkova serrata. In the experiment, the influence of initial conditions of root, i.e. root size, water content and rottenness are investigated. It is proved that the tensile force of each tree root varied widely and there is a difference in tensile forces of root classified by the pot of root. Furthermore, It is also confirmed that the tensile forces of Crytomeria japonica and Carpinus tschonoskii are twice the other trees and displacement of root in break does not depend on a kind of tree and the water content of a root.
