Abstract/Contents: | "Nickel (Ni) toxicity has been well aware of in plants and soils due to increased use of sewage sludge and waste water applications plus a lack of knowledge of Ni toxicity tolerance levels in turfgrasses and other grass species. Annual bluegrass (Poa annua) is one of the most prevalent weedy grasses and difficult to control on creeping bentgrass greens. Therefore, a study was conducted in a walking-in growth chamber to examine Ni tolerance of two cool-season creeping bentgrass (Agrostis stolonifera L.) cultivars (PennLinks II, and Seaside II) turfgrasses plus a mixture of annual bluegrass and annual ryegrass (Lolium multiflorum) with six different Ni2+ levels supplied as NiSO4·6H2O (Control, 200, 400, 800, 1600, and 3200 μg L-1 of Ni) after pilot trials. Grasses were assessed based on visual turf (or grass) quality, NDVI, chlorophyll content (a chlorophyll meter), relative clipping biomass, relative root biomass, relative total biomass, and plant tissue nickel concentration. As Ni concentrations increased, all measured growing parameters decreased and toxicity symptoms became more obvious. Seaside II and PennLinks II at Ni concentrations of 400 and 800 μg L-1 of Ni were noted to be at an acceptable turf quality or higher, while the mixture of two weedy species was below the acceptable grass quality level (using the same 1 to 9 scale). Seaside II displayed an acceptable turf quality even at 1600 μg L-1 of Ni. At 3200 μg L-1 of Ni, PennLinks II and weedy species were necrotic at the conclusion of the study compared to Seaside II which was actively growing with signs of yellowing. The study was repeated twice in the same growth chamber. The results illustrate genetic Ni tolerance differences and Seaside II, a salt tolerant creeping bentgrass cultivar, has stronger Ni toxic concentration tolerance than Penn Links II and mixture of two annual weedy grass species, often found in the transition zone. This also may explore potentials of more research on micronutrient management of weedy species." |
