Triticum aestivum, Cicer arietinum, Vigna radiata, Vigna aconitifoliaKlystron-based EMF generator, 9.6 GHz, 1 dBm to 3.5 dBmGrowth and biomass reduction [41]

Vigna radiata, Ipomoea aquatica425 MHz, 2 h, 1 mWGrowth stimulation of primary root [16]

Glycine max900 MHz, 5.7 to 41 V m−1Inhibition of epicotyl and/or root growth, depending on exposure set-up [9]

Lemna minor400–1900 MHz, 23 to 390 V m−1, whole plant exposureGrowth slowed down, at least in the first days following exposure [18]

Trigonella foenum-graecum, Pisum sativum900 MHz, 0.5–8 hIncreased root size, nodule number, and size [42]

Hibiscus sabdariffaResulting field from a GSM base antenna (not measured) Reduction of flower bud abscission with increasing distances from the antenna [43]
