PROBLEM TO BE SOLVED: To provide a plant physiology activator effectively contributing to the growth acceleration of a plant, particularly, in the growth acceleration after germination of a plant, and also having excellent productive efficiency, and a method for producing the same.SOLUTION: Provided are a plant physiology activator and a method for producing the same. The method for producing the plant physiology activator includes: a step of immersing ulmoides seed into a Cto Calcohol aqueous solution; and a step of immersing the ulmoides seed immersed into the Cto Calcohol aqueous solution into water or a hypochlorite aqueous solution to obtain a ulmoides extract. A plant physiology activator obtained by the method can remarkably increase the growth after germination to the seed and seedling of plant. According to the invention, the productivity of optional dicotyledon and monocotyledon represented by vegetable such as tomato, grain such as rice plant and the other horticultural plant can be increased, thus it is effective in an agricultural field and a horticultural field. |
