RESORPTION OF ORGANIC-COMPONENTS BY ROOTS OF ZEA-MAYS L AND ITS CONSEQUENCES IN THE RHIZOSPHERE .1. RESORPTION OF 14C LABELED GLUCOSE, MANNOSE AND CITRIC-ACID

Abstract:

The re-sorption of carbon compounds from the rhizosphere was investigated using 14C-labelled glucose, mannose and citric acid. Uptake in roots of 5-day-old, intact Zea mays plants in sterile solution culture was determined over a period of 48 hours. Under optimal growth conditions significant re-absorption of glucose and mannose occurred with the uptake rates being 70.5 and 40.2 μg compound g-1 root DW h-1, respectively. For glucose and mannose approximately 25% of the 14C label taken up by t...
