Abstract
The symptoms such as weaken shape, partial and full death in nurse- and old- trees have been mostly caused by the occurrence of cavity. In general, the adaption of poly-urethane has been practised routinely in the way of treatment in cavity. However, the use of poly-urethane was not an effective, but it was related to pollution materials. Here, the experiment was conducted to identify the effects of the treatments of loess or micro-organisms for the alternatives of poly-urethane. The cavities which occurred in Zelkova serrata, Prunus yedoensis and Quercus myrsinaefolia were treated by poly-urethane, loess, mixtured loess and micro-organism (Rhadobacter), and mixtured loess and micro-organism (Rhodobacter + bacillus). As the results of this experiment, it was shown that the treatment of mixtured loess and micro-organism (Rhodobacter + bacillus) induced to develop greater callus formation in the cavity up to 97% in Zelkova serrata, up to 87% in Prunus yedoensis, and by 73% in Quercus myrsinaefolia than the treatment of poly-urethane. But the only loess and mixtured loess and micro-organism (Rhadobacter) was a similar or lower callus formation ratio than poly-urethane.
