The effects of electric field on the growth of intact seedlings and coleoptile segments ofZea mays L.

Type: article
Abstract: The experiments were carried out with 96-h-old intact maize seedlings and 10 mm long coleoptile segments cut 4 mm below the tip. The electric fields were applied longitudinally along the seedlings. The electric field (15 V) caused inhibition of the elongation growth of intact seedlings which was dependent on both the polarity and the duration of the applied voltage. The growth inhibition was greater when the tip of the shoot was positive relative to the roots. The electric field also caused inhibition of indole-3-acetic acid (IAA) and fusicoccin (FC) induced growth of maize coleoptile segments excised from electrically treated seedlings. IAA-induced growth of coleoptile segments was greater when the tip of the shoot was negative to the roots (not in the case of FC-treated segments and intact seedlings). It was suggested that apart from the changes induced by electric field in transport system of auxin the electric field affected also the activity of plasmalemma proton pump.
