Abstract: Ornamental plants bear an important status in the horticultural industry of the world. Plant growth regulators consist of a large group of naturally occurring or synthetically produced organic chemicals and considered as helping tool in the modern production system of ornamentals. Most of the time plant growth regulators are being used by the commercial growers of ornamental plants as a part ofcultural practice. Ornamental crops find extensive use of growth regulators for modifying their developmental processes. Plant growth regulators provide an immediate impact on crop improvement programmes and are less time consuming, applications of plant growth regulators must lead to quantifiable advantages for the user plant growth regulators must be specific in their action and toxicologically and environmentally safe. The physiological activities of flowering crops regulate by the application of growth regulators and finally affect the growth and flower production in flowering crops. Plant growth regulators have quicker impact on vegetative as well as flower yield of flowering crops. There are various methods of application of PGRs but the most popular are foliar sprays, drenching and pre-plant soaking while the efficacy of each method depends on the various factors including the mode of absorption of PGRs by different plant parts, method of application and environmental factors.
