| Abstract/Contents: | "As a result of the positive environmental and social value of lawn areas, turfgrasses have become an important component or urban centers and are used in many different macro and micro climates. A 2 year field experiment was conducted at the Experimental Agricultural Farm of Padova University in Legnaro, Italy, to investigate temporal changes in species composition of three turfgrass mixtures to which a plant growth regulator was applied. Three grass mixtures were established in 2006 and subsequently treated with the plant growth regulator trinexapac-ethyl (Primo) at either half, recommended, or one and half the recommended rate, or left untreated (control). The three turfgrass mixes used were 1) Lolium perenne (40% [by weight]), Festuca rubra ssp. tricophylla (15%), Festuca rubra ssp. commutata (15%), and Poa pratensis (30%); 2) Festuca arundinacea (90%) and Poa pratensis (10%) and 3) Lolium perenne (60%) and Poa pratensis (40%). Species in each mix consisted of 2 varieties in equal proportions. Plots were mowed at 4.5 cm and 15-9-15 fertilizer was applied at 20 gN m-2 yr-1. Treatments were replicated three times in a randomized complete block design, from February 2007 to July 2008 the succession of the species composition of the three mixtures was studied by means of linear analyses method. Plant growth regulator applications did not affect species composition; however there was a shift in plant composition over time for mixtures 1 and 3. Lolium perenne decreased in both mixtures, while a constant increase of Festuca rubra and Poa pratensis was observed in mixture 1 and 3. The composition of mixture 2 stayed stable with Festuca arundinacea as the dominant species. Results indicate that under climatic and management conditions prevalent in this study. Lolium perenne can disappear rather rapidly while Primo has no effect on changes in species composition." |
