Role of plant growth regulators in floriculture: An overview

Abstract

Plant growth regulators are being used by the commercial growers of ornamental plants as a part of cultural practice. Plant growth regulators have quicker impact on vegetative as well as flower yield of flowering crops. As it have various advantages like less time consuming to treat the plant and environment friendly. There are various factors contributing to the efficacy of plant growth regulators among them the method of application plays a key role in determining the effectiveness of plant growth regulators, as PGRs can be effective if properly absorbed by plants. Use of growth regulators in flowering crops must be specific 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. In the present overview, we discuss the types of plant growth regulators their effect and its applications in flowering crops.
