The invention specifically discloses a method for direct regeneration of an adventitious bud from a Jatropha curcas petiole explant, which belongs to the field of plant biotechnology. The method improves a traditional method for regeneration of the adventitious bud from the Jatropha curcas petiole explant; i.e., instead of addition of hormone into a culture medium which induces regeneration of the adventitious bud, a high-concentration thidiazuron solution is used for short-period soaking treatment of the Jatropha curcas petiole explant so as to give short-period but high-intensity hormone stimulation to explant cells, thereby allowing a part of the cells to undergo more highly efficiently direct redifferentiation so as to form more adventitious buds.
