Abstract:
Quantitative and qualitative changes of essential oils during the development of clonal plants of fennel propagated through somatic embryogenesis were investigated. Although no essential oil could be detected either in cultured cells or in somatic embryoids, monoter-penes such as alpha-phellandrene and alpha-pinene were found in radical leaves of regenerated plantlets cultured on a hormone-free agar medium. The regenerated plants cultivated in the field for about one month accumulated phenylpropanoids such as estragole, anethole, and fenchone in addition to the two monoterpenes described above in radical leaves. Rich accumulations of phenylpropanoids and monoterpenes were observed in the fruits; especially the contents of estragole and anethole were much higher than in radical leaves.
