Treatment agents are provided for cell seedlings. Each treatment agent comprises water, a dispersant, and activated carbon finely dispersed with the dispersant in the water. Potted seedlings can be treated by dipping them in the treatment agent and/or by irrigating them with the treatment agent. In this manner, cell seedlings can be pre-treated before planting. The thus-planted seedlings may be irrigated with the treatment agent.

Compositions and method for treating potted seedlings, and method for planting same

A lawn colorant composition having rearing effects contains a pigment and an adhesive for the pigment. The pigment comprises a blue pigment composed as a primary component of a compound represented by the following formula: MFe&lsqb;Fe(CN) &rsqb; wherein M represents an alkali metal atom or an ammonium group, one of the two Fe atoms is a divalent ion, and the other Fe atom is a trivalent ion. The adhesive comprises a water-dispersed polymer and a water-soluble polymer having compatibility with said water-dispersed polymer.

Lawn colorant composition having rearing effects

A lawn colorant composition having rearing effects contains a pigment and an adhesive for the pigment. The pigment comprises a blue pigment composed as a primary component of a compound represented by the following formula: MFe&lsqb;Fe(CN),&rsqb; wherein M represents an alkali metal atom or an ammonium group, one of the two Fe atoms is a divalent ion, and the other Fe atom is a trivalent ion. The adhesive comprises a water-dispersed polymer and a water-soluble polymer having compatibility with said water-dispersed polymer.

A plant growing agent contains a blue pigment that contains, as a main ingredient, a compound represented by MFe�Fe(CN).sub.6 ! (M is an alkali metal or an ammonium group, and one Fe is of divalent, while the other Fe is of trivalent), and a substance for changing the cuticular of the surface layer of a plant so as to facilitate permeation of the blue pigment into the interior of the tissue of the plant. In a plant growing method, a thick stock solution is first prepared by adding a surfactant and a solvent into a mixture of the above-described blue pigment and the above-described substance for changing the cuticular of the surface layer of a plant so as to facilitate permeation of the blue pigment into the interior of the tissue of the plant. The thick stock solution is diluted 5-100 times with a solvent, and is sprayed onto a plant to be grown.
