Mass propagation of medicinal plants in hydroponic
condition, especially in salt soils have a special
importance. The experiment was conducted as a factorial
and in a completely randomized block design
Hydroponically grown O. basilicum L. plants were
exposed to 4 levels (0, 25, 50 and 100 mg/l) of Multiwalled
carbon nanotubes treatment and 3 levels (0, 50 and
100 mM NaCl) of salt stress. Plants daily irrigated with
quarter-strength Hoagland solution and Harvested
inflorescences and leaves of each sample were air dried at
room temperature. The hydro-distilled oils were analyzed
by GC/MS. Fifty components were identified in the
inflorescence and leaf essential oils of the basil plants.
Salinity and MWCNTs treatment in low to moderate
concentration increased the essential oil percentage.
Results demonstrated the major pathway of the essential
oil was Phenylpropanoids pathway that main constituents
was estragole and in shikimic acid pathway the main
constituents linalool was identified that were (60/48 % and
10/18%), respectively. -cadinol, Caryophyllene, and
Germacrene D were the other the most constituents that
(4/26%, 4/92 and 6/56%) respectively. In total, considering
the previous reports, it seems that the essential oil
composition of hydroponically grown O. basilicum L. had
volatile constituents probably with potential applicability
in the pharmaceutical and food industries.
