Micropropagation of Citrus

The genus Citrus is cultured in more than 100 countries making it one of the most important commercial fruit crops in terms of economic value and human nutrition (Barlass and Skene, 1986). Fresh fruits and juice are the most significant citrus products, but essential oils, pectin, and marmalade, as well as candied and dried rinds, also have commercial value (Barlass and Skene, 1986). In recent years, the importance of Citrus for the production of ornamental plants has increased considerably (De Pasquale and Carimi, 1998).
