ABSTRACT
The aim of this study was to investigate the effect of selenium trace element supplemented with fulvic acids andhumic acids on some trait of Anethum graveolens L. This experiment was conducted in a completely randomizedblock design with three levels of fulvic acids and humic acids (0, 15, and 50 mmol/l) and selenium application infive levels (0, 6, 8, 12, and 16 mg/l) with three replications in the greenhouse at Tehran municipality. The resultsof 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 wereaffected by increasing Se, humic and fulvic acids levels. Results indicated that selenium along with acidsincreased some major oil components, including ɑ-Pinene, β-Myrcene, ɑ-Phellandrene, and Carvone.
