PURPOSE:To provide an easily available plant-growth promoting agent having sufficiently high activity to promote the rooting, elongate the height of seedling and prolong the life of a plant, by combining vitamin B1, vitamin B6 and nicotinamide. CONSTITUTION:The objective plant-growth promoting agent contains vitamin B1, vitamin B6 and nicotinamide which are easily available in the market. The concentration of each component is 10-300ppm, preferably 50-200ppm in the case of using the agent as an aqueous solution. Growth of a plant can be effectively promoted by the use of even an extremely small amount of the plant- growth promoting agent. Besides the effect for growth, the agent prolongs the life of a plant, activates a plant and improves the luster of leaf. |
