Na. Belova et Vv. Lednev, Activation and inhibition of gravitropic response in plants by weak combined magnetic fields, BIOFIZIKA, 45(6), 2000, pp. 1102-1107
It is shown that the rate of gravitropic response in the segments of stems
excised from millet, flax and clover seedlings may be considerably activate
d or inhibited by the application of weak combined magnetic fields tuned to
the parametric resonance for Ca2+ or K+, correspondingly.
