摘要: Pressure within guard cells in strips of intact epidermis Tradescantia virginiana was controlled with a pressure probe apparatus after the had been filled silicone oil. increased and decreased incrementally between 0.0 4.1 MPa to cause inflation deflation cells. At steady-state cell pressures, width stomatal pore recorded plotted against pressure. The required for near-maximum aperture MPa. Aperture as function sigmoidal.
