Abstract/Contents: | "Many biotypes of annual bluegrass (Poa annua L.) are found on golf course putting greens. Although normally considered an invasive weed, annual bluegrass can provide as good a putting surface as creeping bentgrass (Agrostis palustris Huds.). The most desirable biotypes of annual bluegrass are primarily vegetative and have a low flowering frequency. Whether the nutritional requirements of annual bluegrass biotypes differ from one another or from creeping bentgrass is unknown. The response of three flowering (FAB, high seedhead production) and three vegetative (VAB, low seedhead production) biotypes of annual bluegrass (AB), and the three parents of 'Penncross' creeping bentgrass (CB) to varying levels of iron (Fe) in greenhouse sand culture was investigated. After establishment, clones were grown for 3 weeks and irrigated with a half-strength Hoagland's solution containing 0, 2, 4, 6, and 8 mg路L-1. Shoot dry weight of AB increased significantly with Fe treatment level up to 6 mg路L-1. Root growth of CB increased up to 4 mg路L-1 Fe, but then decreased significantly at 8 mg路L-1 Fe. Root growth of AB increased slighly up to 4 mg路L-1 Fe and then declined at 6 and 8 mg路L-1. Shoot tissue concentrations of Fe were similar for AB and CB at each Fe rate tested except at 8 mg路L-1 Fe, where Fe levels in CB were significantly lower. Based on this work, creeping bentgrass and annual bluegrass respond differently to Fe nutrition, but different biotypes of annual bluegrass appear to respond similarly." |
