| Research Abstract |
The main objective of this work was to analyze the translocation of the stimulation induced by the dormancy-breaking chemical (cyanamide) from the adjacent tree grafted by the 'tree joint' method in order to elucidate the mechanism of in poorly synchronized flowering and adaptation problems in releasing from dormancy of deciduous fruit tree influenced by global warming. The effect was conducted from the adjacent tree through the graft union, therefore, it was suggested that the outside organ of a dormant bud affected its breaking dormancy.
