Anthemis gilanica, is a medicinal plant, belonging to the Asteraceae family, is distributed in the north of Iran. The magnetic field is one of the abiotic stresses that can affect the growth and development of living organisms. Today, much attention has been paid to the biological effects of these fields and is used as a technique in biological studies such as plant growth, germination percentage, and secondary metabolites changes. In this research, in order to study the leaching processes, A. gilanica seeds were placed in the Murashige and Skoog (MS) media under magnetic field intensities (0, 2, 4 and 6 millitesla) for one hour and after one month were harvested for physiological and biochemical analyzes. The results showed that the magnetic field in 4 millitesla resulted in a significant increase of chlorophyll a, b, total chlorophyll, magnesium protoporphyrin, protochlorophyllide, protoporphyrin (P ≤ 0.05). Increasing the intensity of the magnetic field resulted in a significant increase in the germination percentage of the seeds compared to the control sample and the highest content of the pigments and precursors in the treatment were observed at 4 millitesla. It seems that magnetic field in proper intensity can be used as a suitable method for enhancing the germination and content of A.gilanica plant pigments
