| Abstract/Contents: | "Tall fescue (Festuca arundinacea Schreb.) seedlings were grown in an intermittently irrigated gravel culture system in the greenhouse. Nutrient molybdate levels were 0, 0.1, or 0.21 μequiv./L with sulfate levels of 0 to 1.0 mequiv./L. Leaf tissue was harvested 28, 42, and 49 days after seeding. Molybdenum content of leaf tissue increased with increased solution Mo concentration. Increased solution SO42- levels increased tissue S and nitrate reductase activity (NRA), but decreased tissue Mo and NO3- content. When low tissue S was limiting NRA, and when Mo and NO3- were available, NRA was not increased by 2- to 4-h incubations of leaf tissue in SO42- solution. The MoO42- x SO42- interaction for tissue Mo concentration was significant and the effect of SO42- was relatively greater in the presence of Mo than in the absence of Mo. 99Mo root uptake studies indicated the first increment of SO42- added to nutrient solution results in the greatest reduction in Mo accumulation. The data indicated that the greatest effect of SO42- on leaf Mo levels occurred during the absorption process with small reduction of Mo translocated from root to leaf tissue." |
