The cut flower industry is an increasingly globalized market, of economic importance worldwide. It relies on the transport of high value and high-quality flowers across long distances. Flowers follow a genetically controlled developmental program that starts with floral initiation and ends with petal senescence and often abscission. Ethylene is a key regulator in this senescence process in many species. Understanding which species or varieties are more or less ethylene sensitive and controlling ethylene through the flower supply chain is a major contributor to flower quality for the consumer. Our understanding of ethylene biosynthesis and signaling is largely based on model species such as Arabidopsis. However, a better understanding of ethylene in different floral organs, in different species and interactions with other growth regulators is emerging and is reviewed in this chapter. Several approaches have been tried for delaying floral senescence through manipulation of ethylene levels and ethylene perception both through chemical means and by generating transgenic lines. The success of these approaches to date is considered, and future technologies are reviewed for their application to floriculture.
