To provide a plant growth promoter constituted of a physiologically active substance such as a polyamine, and a biochemical energy material such as creatine phosphate, and further to provide a cultivating method by which the growth of the plant is promoted.
It is known that the biochemical energy material such as creatine phosphate has activities for promoting the growth of the plant, and the addition of the physiologically active substance such as the polyamine thereto can improve the effects. The effects are provided by the phosphorylation of the polyamine by the creatine phosphate, or the addition of the biochemical energy effects of the creatine phosphate to the physiological effects of the polyamine. When the plant growth promoter consisting of the physiological active material and the biochemical energy material is added to the plant, the plant grows well and provides high yield.
