摘要 |
An agent for improving lawn grass quality, which is excellent in promoting dwarfing of lawn grass, making the stem sturdy, increasing the leaf count, and improving greenness, is provided.;An agent for improving lawn grass quality containing, as active ingredients, 5-aminolevulinic acid represented by formula (1):
R2R1NCH2COCH2CH2COR3 (1)
wherein R1 and R2 each independently represent a hydrogen atom, an alkyl group, an acyl group, an alkoxycarbonyl group, an aryl group or an aralkyl group; and R3 represents a hydroxyl group, an alkoxy group, an acyloxy group, an alkoxycarbonyloxy group, an aryloxy group, an aralkyloxy group or an amino group,
or a derivative thereof or a salt of the acid or the derivative, and a gibberellin biosynthesis inhibitor. |
