STIMULATION OF ROOTING OF OLD TREES BEFORE TRANSPLANTATION |
| Authors: | G. Gombkoto, P. Bercsek |
| Abstract:
The effect of root-pruning and hormone treatment was studied on the root regeneration of different tree species. For some of them /Populus, Fraxinus/ a single root pruning already initiated an intensive formation of new roots. In the case of others, however, root pruning resulted in poor new root development with bad quality. The positive effect of combining the root pruning with a chemical treatment was well marked in these species. /Quercus, Elaeagnus, Malus, Pinus/. When preparing old trees for transplantation it is advisable to give them a root-treatment with chemicals. One of the best compounds is alphanaphtylacetic acid, which stimulates the root formation of all species. New roots are forming in great quantities resulting in a compound and well interwoven soil ball, an active and healthy root system and a good and safe establishment of the trees after transplanting. | |
