| Abstract/Contents: | "The effects of nitrogen nutrition on cell membrane stability (CMS), leaf water potential, N, K, P, Ca, Mg, and glycine-betain concentrations in C3 plant, Agrostis palustris Huds. (creeping bentgrass) were assessed under water-stress conditions. Water-stressed plants showed greater adaptation to water stress at higher nitrogen (N) levels. Cell membrane stability measured by the polyethylene glycol (PEG) technique was increased by increased N application. Osmotic potential decreased and turgor pressure increased N application. Nitrogen, K, Ca, and glycinebetaine concentrations in leaf tissues increased with increased N application under water-stress conditions." Malondialdehyde (MDA) concentration in leaves which is an indicator of lipid peroxidation, was greater in the water-stress treatment than in the control, however, MDA concentration decreased with increased N application in the water-stressed plants. The results suggested that higher levels of N nutrition may have contributed to drought tolerance in creeping bentgrass by preventing cell membrane damage and enhancing osmoregulation. |
