Abstract
Hormones are vital to plant growth, and lacking them, plants would be mostly a mass of undifferentiated cells. The word 'hormone' is derived from a Greek term that means 'to excite.' These Plant hormones are also known as Phytohormones or Plant growth substances. The term 'Phytohormone' was coined by Thimann in 1948. Hormones helps to shape plant by affecting seed growth, time of flowering, sex of flowers, senescence of leaves, and fruits. They also affect the leaf formation, stem growth, fruit development and ripening, plant longevity, and even plant death. Hormones determine the formation of flowers, stems, leaves, shedding of leaves, and the development and ripening of fruit.
