Role of Plant Growth Regulators in Flower Crops

Rachel Vanlalhruaii, Shilpa Kamal, Shabnam Pangtu

Plant growth regulators consist of a large group of naturally occurring or synthetically produced organic chemicals and considered as a helping tool in the modern production system of ornamentals. Their exogenous application helps to improve the different economically important and market desirable characteristics of ornamental plants. The effects of PGRs in plants depend on various factors which play an important role to achieve expected results. These factors include the application method, time of application, concentration of PGRs, plant species and also the environmental conditions in which plants are grown. The intensity of applications is also considered an important factor affecting the efficacy of PGRs, as some plants respond well to a single application, but in most cases, multiple applications are beneficial to attain good results. This review briefly discusses the different areas in which PGRs are used in flower crops.
