[Activation and inhibition of the gravitropic response in the flax stem segments exposed to the permanent magnetic field with magnetic density ranging from 0 to 350 microT].
It was found that the rate of gravitropic bending in apical segments excised from 4-day-old etiolated seedlings of flax Linum bienne is strongly and nonlinearly dependent on the value of the magnetic flux density of a static magnetic field, BDC, in the range from 0 to 350 microT. The gravitropic bending is stimulated at 0 < or = BDC < or = 2 microT and 200 < or = BDC < or = 350 microT but is inhibited at 100 < or = BDC < or = 170 microT relative to control samples being in the magnetic field of the Earth equal to 46.5 microT.
