    摘要: A novel method for accelerating growth of a plant in agriculture and forestry is proposed in which an organosilicon compound .omega.-carboxyalkylsilicon sesquioxide, e.g. 2-carboxyethylsilicon sesquioxide, of the unit formulaHOOC(CH.sub.2).sub.n SiO.sub.1.5,in which n is a positive integer of 1 to 4, is applied to the plant directly or to the soil in which the plant is growing. The metal salts or complexes of the above compound as well as the precursor compounds thereof readily convertible to the silsesquioxide compound by hydrolysis are also effective.
