Objective: Cilantro (Coriandrum sativum L.) is an annual herbaceous plant of the umbrella family which widely used in the food, cosmetic and pharmaceutical industries. The presence of plumbum (Pb) in the environment, a major environmental pollutant, has devastating and irreversible effects on the ecosystem. This study aimed to examine the effect of different levels of plumbum and Trichoderma fungus "Trichoderma harzianum" on the growth and physiological properties of Cilantro. Methods: In this context, an experiment was conducted as a factorial in the form of completely randomized design with three replicates to examine the effects of plumbum in three levels and Trichoderma fungus in two levels on coriander plant and phytochemical properties and plumbum were measured. Results: The results showed that the highest chlorophyll a, b and total chlorophyll (1.644, 0.892 and 2.345 mg/g of fresh weight) was observed in the interactions between plumbum (0 mmol/L) and 20% of Trichoderma treatment. Also, the highest amount of anthocyanins (0.049 mmol/g of fresh weight) and essential oil percent (0.525%) was observed in the interaction between plumbum (2 mmol/L) and 20% of Trichoderma treatment. The highest amount of linalool (43.869%) was observed in the interaction between plumbum (0 mmol/L) and 20% of Trichoderma treatment. Also, percentage of free radicals (49.871) was observed in the interactions between plumbum (0 mmol/L) and 20% of Trichoderma treatment. Conclusion: The results of this study showed that treatments with interaction plumbum and Trichoderma fungus can be a useful and better promising.
