| Popis: | Culture conditions and salt effects on essential oil composition of sweet marjoram (Origanum majorana) from TunisiaO. majoranashoots were investigated for their essential oil (EO) composition. Two experiments were carried out; the first on hydroponic medium in a culture chamber and the second on inert sand in a greenhouse for 20 days. Plants were cultivated for 17 days in hydroponic medium supplemented with NaCl 100 mmol L-1. The results showed that theO. majoranahydroponic medium offered higher essential oil yield than that from the greenhouse. The latter increased significantly in yield (by 50 %) under saline constraint while it did not change in the culture chamber. Under greenhouse conditions and in the absence of salt treatment, the major constituents were terpinen-4-ol andtrans-sabinene hydrate. However, in the culture chamber, the major volatile components werecis-sabinene hydrate and terpinen-4-ol. In the presence of NaCl, new compounds appeared, such as eicosane, spathulenol, eugenol, and phenol. In addition, in the greenhouse, with or without salt, a very important change oftrans-sabinene hydrate concentration in EO occurred, whereas in the culture chamber change appeared incis-sabinene hydrate content. |
