Role of Growth Regulators in Production of Essential Oils in Aromatic Crops

The growth and development of aromatic plants, containing essential oil, may be influenced by many factors like genetic, climatic factors and agronomic practices. Among the different management practices, growth regulators influence the essential oil content in the aromatic crops. Most of the growth regulators like gibberellins, brassinolides, kinetins, NAA and CCC are most effective in improving quality of aromatic crops. Use of appropriate growth regulators at optimum concentration and right stage of the crop growth can increase the herbage and essential oil yield of aromatic crops.
