Fig. 2From: The effect of DC electric field on the elongation growth, proton extrusion and membrane potential of Zea mays L. coleoptile cells; a laboratory studyBending of coleoptiles in seedlings untreated (A) and treated (B) with EF (+10 V/180 min) in response to 90° gravistimulation. After the displacement of maize seedlings into a horizontal position (90°) the gravitropic bending of coleoptiles was measured in 30 min intervals for 300 min (see Methods)Back to article page
