Surface potentials and hydraulic signals in wheat leaves following localized wounding by heat

  title={Surface potentials and hydraulic signals in wheat leaves following localized wounding by heat},
  author={' M.MALONE and B. STANKOVlC},
  • Published 2005
Localized burning of a leaf causes a rapid change in apoplastic electrical potential throughout the shoot of wheat seedlings ('variation potential'). It also causes marked increases in turgor pressure in epidermal cells of adjoining leaves. These turgor increases indicate rapid propagation throughout the seedling, of a hydraulic pressure wave from the site of wounding. Evidence is presented that this pressure wave is caused by relief of xylem tension, by water released from damaged cells in the… CONTINUE READING
