Two Thai varieties of lemon grass, two other varieties from Malaysia and Izu, all being Cymbopogon citratus according to their morphological features and the physical and chemical properties of the essential oils, were cultivated for 6 years in Kyoto, Japan and their essential oil composition was analysed. Scarcely any difference was observed in the essential oil compositions, though the essential oil content of Thai varieties was significantly higher (0.30-0.54%) than those of the other two varieties. The Thai varieties were more resistant to cold weather and survived the coldest winter in Kyoto. Callus was induced from basal part of leaf blades of Thai lemon grass on Linsmaier-Skoog medium containing 10^<-4> m of 2,4-dichlorophenoxyacetic acid (2,4-D), and subcultured on a medium containing 10^<-5> m 2,4-D. The callus differentiated into plant when transferred to a medium supplemented with 10^<-7> m 2,4-D and 10^<-5> m kinetin. The plant thus induced from callus was, when grown in soil, almost identical with the original plant with the same morphological features and the same essential oil composition.
