Effect over the elongation growth acceleration of root segments of Zea Mays L. due to elevated external pressure

摘要: Abstract The effect of elevated external pressure on the acceleration elongation growth in maize root segments was studied. rate increases approximately by 2–2.5 times with increase up to 0.5–1 MPa. dependence segments’ magnitude is shown for 0.25–2 MPa. Pre-treatment a mercury chloride solution, which inhibits transmembrane water transfer roots, virtually removes pressure, indicates physiological nature under impact pressure. assumed be associated potential within apoplasm (cell walls, xylem) caused An additional reason can dissolved oxygen concentration cells and tissues such experimental data presented paper qualitatively are agreement results mathematical model literature, accounts parameter apoplasm.
