This study was conducted to investigate the combined and independent effects of drought stress and copper on vegetative traits (root length, stem length, fresh and dry weight of seedling), essential oil content and copper accumulation in roots, shoots and distilled plant material of Fumaria parviflora Lam. In this study, different concentrations of copper (control, 50, 150, 300 and 400 mg /kg) and different levels of drought stress (control, 50% and 75% based on soil moisture percentage discharge) on seeds collected from two mineral regions in Kerman province (Askari and Rabar) and in each region four zones (Z1, Z2, Z3 and Z4) were used. The results showed that in all treatments, the concentration of 50 (mg / kg) copper without drought stress (control) led to the highest value in terms of vegetative traits.The highest percentage of essential oil (0.45) in the treatment with concentration 150 (mg / kg) of copper and medium drought stress in zone 3 of Askari copper mine and the highest concentration of copper in roots, shoots and distilled plant material in treatment with 400(mg /kg) copper and severe drought stress in zone 3 of Askari mine were observed. In this study, the Cu remained in the plant tissue during the distillation process and the concentration of copper in the distilled plant material was almost similar to the concentration of plant shoots before the distillation process. The best treatment for f. parviflora cultivation in terms of plant essential oil, 150 (mg / kg) copper and medium drought stress was evaluatedthese findings support the use of F. parviflora as an acceptable species for soils that are in moderation contaminated with copper. behaviors such as slow growth and severe decline in biomass at high concentrations of Cu, it is concluded that the F. parviflora cannot be a candidate species for the phytoremediation of copper contaminated soil.
