Effect of weak permanent magnetic field on lipid composition and content in perilla leaves

Composition and content of lipids were studied in leaves of red perilla plants (Perilla nankinensis [Lour.] Decne.) grown in weak permanent horizontal magnetic field (PMF) of 500 µT flux density under controlled illumination, temperature, and humidity in the phytothron chamber. Control plants were grown under similar conditions, but without PMF exposure. Exposure of perilla plants for a month to PMF retarded plant flowering as compared to control. PMF treatment increased total lipid content, including polar lipids, among them glycolipids and phospholipids. PMF did not affect content of neutral lipids. It is concluded that PMF stimulated synthesis of membrane lipids of chloroplasts, mitochondria, and cytoplasm in perilla leaves. A possible role of PMF as a factor imitating the additional light source retarding flowering of a short‐day perilla plants is discussed. Bioelectromagnetics. © 2016 Wiley Periodicals, Inc.
