Transport of Water and Solutes across Maize Roots Modified by Puncturing the Endodermis (Further Evidence for the Composite Transport Model of the Root)



Transport of Water and Solutes across Maize Roots Modified by Puncturing the Endodermis (Further Evidence for the Composite Transport Model of the Root)



Plant Physiology 103(2): 335-349



The effects of puncturing the endodermis of young maize Tanker roots on their transport properties were measured using the root pressure probe. Small holes with a diameter of 18-60 micro m were created 70-90 mm from the tips of the roots by pushing fine glass tubes radially into them. Such wounds injured about 10-2-10-3% of the total surface area of the endodermis, which, in these hydroponically grown roots, had developed a Casparian band but no suberin lamellae.
