| Abstract | ||
| This work was conducted in two successive seasons 1998 & 1999 in the Experimental Farm of the Medicinal and Aromatic Plants in El-Kanater El-Khayria Egypt. The aim of the present work is to study the growth pattern, herbage yield, oil production and composition as well as oil properties of three cultivars belong to two species of the genus Cyrn. bopogon Which were C. citrates (EI-Kanater type), C. citrates (El-Farafra type) and C. nardus. Results were recorded for growth characters i.e. plant height, til-lers no., fresh and dry weights (gm/plant). It was found that, there were some differences in growth characters between the three cultivars. C citratus (El-Kanater type) recorded the highest values with respect to plant height, tillers no. fresh and dry weights (gm/plant). Also, it was ob-served that, absolute growth rate was found to be in harmony with growth behaviour of each cuftivar. With regard to essential oil, results pointed out that, C. nardus was highest in oil percentage, however the highest oil yield (ml/plant) was obtained from the C. citratus (El-Kanater type). As for oil properties it was found that, values of physicochemical properties of the three oils met those of standards. Regarding oil composition it could be concluded that, the oil of the El-Kanater lemongrass contained citral (the main component) and geraniol (the second main component) higher than those in the oil of ElFarafra lemongrass. Citronella oil contained values of geraniol, citronellol and citronellal agreed with the values of standards. | ||
