Figure 7From: Growth of etiolated barley plants in weak static and 50 Hz electromagnetic fields tuned to calcium ion cyclotron resonanceMicrophotos of leaf tissues. Plants were grown initially 5d etiolated, then 7d in the light. Microphotos A and B belong to sections of plants additionally exposed to Ca2+ ICR condition (BDC = 65 μT, f(BAC) = 50 Hz) during the 5d etiolation phase, while C and D are from comparable preparations of controls grown under the same conditions, but without Ca2+ ICR. A and C are taken under tungsten light, B and D under fluorescent illumination (380 nm). The plants grown at the Ca2+ ICR seemingly show a lower chloroplast density and an increased (red) fluorescence caused by free chlorophylls.Back to article page
