Read More This study investigated the inﬂuence of inoculation with an arbuscular mycorrhizal fungus (AMF), Glomus mosseae (Nicol & Gerd.) on essential oil yield and composition of Different Parts of Dill (Anethum graveolens L.) affected by three different levels of salt stress. The experiment was arranged as a factorial in Randomized Complete Block Design (RCBD) with three replications. Experimental treatments including: three levels of salinity stress (0 (control), 60 and 120 µm), two levels of inoculation (inoculation and non inoculation) and Three organs of the plant (leaves, flowering shoots and mature seeds). The essential oil contents were isolated by hydrodistillation and analyzed by GC and GC/MS. Salinity had significant effects on the essential oil percentage and yield of leaves, flowering shoots and mature seeds. The percentage and yield of essential oil contents of seeds and flowering shoots were much higher than those of leaves under all salinity treatments. Essential oil percentages of seeds and flowering shoots were considerably higher, when plants were subjected to moderate stress. The results pointed out that there was not a significant interaction between non mycorrhizal and mycorrhizal inoculation on essential oil percentage. However,The plants inoculated with AMF had signiﬁcantly greater essential oil yield than the control plants at all salinity levels. The main oil constituents in organs were α –phellandrene, carvone, Linonene, α – thujene, dillether and dihydrocarvone. Salinity had significant effects on these components.Although, α – thujene percentage decreased in salt stress conditions. The Flowering shoots had greater α –phellandrene and carvone than the seeds, while Linonene of seeds was more than flowering shoots and leaves.The AMF induced a higher increase in these components in response to salinity. AMF colonization notably increased α –phellandrene and carvone in flowering shoots. The linonene percentge was higher in seeds of mycorrhizal than nonmycorrhizal plants under salt stress conditions.
