Table 1 Overview of the most important data for growth and pigment contents of barley plants grown under Ca2+ ICR conditions of BDC = 65 μT and f = 50 Hz, and of the corresponding control cultures grown in the absence of an EMF. The right column indicates the ratios of the data.

From: Growth of etiolated barley plants in weak static and 50 Hz electromagnetic fields tuned to calcium ion cyclotron resonance
