The aim of this study was the investigation of the effect of selenium trace supplemented with Fulvic acids and Humic acids on some trait of Anethum graveolens L. This experiment was conducted in a completely randomized block design with three levels of Fulvic acids and Humic acids (0, 15 and 50 mmol/ L) and Selenium application in 5 level (0, 6, 8, 12 and 16 mg/L) with three replications in the greenhouse at Tehran municipality. The results of this experiment showed that the effect of selenium, at different acids on morphological traits was significant. So that the dry weight of shoot and root, plant height, ion leakage, chlorophyll and antioxidant enzymes were affected by increasing treatment levels. Results indicated that selenium along with acids increased some major oil components include ɑ-Pinene, β-Myrecene, ɑ-Phellandene and Carvone
