Barley Growth, Water Use, and Mineral Composition as Influenced by Oxygen Exclusion from Specific Regions of the Root System1

Four treatments applied to the upper and lower halves of barley root systems consisted of A/A, N/A, A/N, and N/N where N represents very low oxygen (<1%) and A represents adequate oxygen in the order of upper/lower halves. Root weight in the upper half of A/A was similar to that in A/N and N/N was similar to N/A. In the lower half, the root weights of A/A and N/A were about equal and A/N equated N/N. Most water was removed from the half which had adequate oxygen. Top growth was highest under A/A and lowest under N/N.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
