| Abstract/Contents: | "Irrigation with non-potable water is becoming frequent in the turfgrass industry. this study was conducted to confirm that the use of metabolic enhancers on creeping bentgrass (Agrostis palustris Huds.) reduces the negative effects of saline irrigation and to ascertain the relation of leaf proline to salinity. Metabolic enhancers are non-mineral substances that, when exogenously applied in very small quantities, stimulate the metabolic activities in plants. Field grown creeping bentgrass was treated with propiconazole (PPC) (30g 100m-2) or seaweed (SE) (Ascophyllum nodosum) extract plus leonardite humic acid (HA; 80%) (3.5 g m-2 and 7 g 100 m-2 respectively). The irrigation treatments of municipal water with 3000 mg L-1 (4.7 dS m-1) of NaCl and 6000 mg L-1 (9.4 dS m-1) of NaCl were applied twice a week. Increasing salinity reduced root mass, leaf mass, photochemical activity (PA) and increase leaf Na, leaf firing and leaf proline content. Under the highest salinity regime the bentgrass treated with PPC consistently had a larger proline concentration, root mass and PA, but less leaf Na content and % leaf firing than the non-metabolic enhancer treated plants. Results from the SE+HA treatment under this saline regime were similar, except the increase in PA and decrease in Na content were not significantly different from the control. Results confirm that salinity impact on bentgrass was lessened with application of selected metabolic enhancers. This may be associated with limiting Na uptake. The influcence of the metabolic enhancers appears to have more impact on endogenous metabolism than just osmotic adjustment, because of increase proline content in negating salinity effects." |
