Abstract:
Growth regulator is an organic compounds other than nutrients, which when used in minute quantities can either inhibit, stimulate, or alter growth. Plant growth retardants are synthetic compounds used to retard the shoot length of plants in a desired way without changing developmental patterns or evoke phytotoxic effects. This has been achieved not only by reducing cell elongation but also by lowering the rate of cell division and regulating the plant height physiologically (Rademacher, 2000). Most plant growth retardants inhibit the formation of growth-active gibberellins (GAs) and can thus be used to reduce unwanted shoot elongation (Singh, 2004). Plant growth retardant may also increase the number of lateral shoots, resulting in a larger number of inflorescences (Whealy et al. 1988).
