The market for cut flowers is becoming more and more international and significant from the perspective of the economy. It depends on the long-distance delivery of expensive and superior flowers. The growth, reproduction, and senescence of a plant's primary organs-leaves, flowers and fruits-occur during the complex juvenile/maturity transition. Several genetic networks are involved in the growth and senescence of leaves, flowers and fruits. One of these networks includes the phytohormone ethylene, which works in conjunction with other hormones to integrate various signals and enable the onset of conditions that are supportive for stage progression, reproductive success, and organ longevity. Since ethylene speeds up processes like ripening and de-greening as well as harmful ones like over-ripening, senescence, and softening, as well as causing significant annual losses of horticultural produce, it is extremely important in postharvest technologies. The perception of ethylene, its level, and the hormonal interactions all directly or indirectly affect how long plants live. Numerous approaches have been tried to prolong floral senescence, including chemical manipulation of ethylene levels and perception as well as the creation of transgenic lines.
