The indiscriminate use of wireless technologies, particularly of cell phones, has increased the health risks among living organisms including plants. We investigated the impact of cell phone electromagentic fi eld (EMF) radiations (power density, 8.55 µW cm–2) on germina- tion, early growth, proteins and carbohydrate contents, and activities of some enzymes in Vigna radiata. Cell phone EMF radiations signifi cantly reduced the seedling length and dry weight of V. radiata after exposure for 0.5, 1, 2, and 4 h. Furthermore, the contents of pro- teins and carbohydrates were reduced in EMF-exposed plants. However, the activities of proteases, Į-amylases, ȕ-amylases, polyphenol oxidases, and peroxidases were enhanced in EMF-exposed radicles indicating their role in providing protection against EMF-induced stress. The study concludes that cell phone EMFs impair early growth of V. radiata seedlings by inducing biochemical changes.

Key words: Cell Phone Radiations, Seedling Growth, Biochemical Changes
