Plant growth regulators are chemicals known to control and alter the physiological functions of plants. They may be synthetic or natural. The majority of the time, plant hormones and phytohormones that plants release in extremely low concentrations are regarded as natural growth regulators. When applied to various plant parts, plant growth regulators quickly move through plant tissues and are readily absorbed by plants. Additionally, a single PGR has the power to affect a variety of plant processes, but they must be handled properly to increase their efficacy in improving various plant growth and developmental processes, plant quality parameters, yield and implementing their environmentally safe use. Plant growth regulators include Auxins, gibberellins, Cytokinin, ethylene, abscisic acid. In the present review we will discuss the effect of two major plant growth regulators i.e., gibberellic acid and benzyl adenine on various ornamental crops.
