Improving aesthetic and diversity of bermudagrass lawn in its dormancy period
Among warm season grasses, Cynodon dactylon (L.) Pers, commonly called bermudagrass, is one of the species that better tolerates drought stress and is the most widely employed for turf in Italy.When temperatures drop below 0 °C, bermudagrass plants enter dormancy and eventually leaves turn brown. In spring, exit from dormancy occurs when soil temperatures persist for several days with an average above 10 °C. The management of an ornamental turf during dormancy could include the use of other herbaceous species able to enhance aesthetic quality, although no study has so far been carried out on the potential for combined planting of warm season grasses, wildflowers and/or bulbous species. The present study was carried out to (a) evaluate the possibility of integrating into the dormant Cynodon dactylon x C. Transvaalensis cv. Tifway 419 lawn some plants able to enhance the ornamental aspect and biodiversity, (b) attempt to identify the best species, (c) observe phenomena of competition, and (d) define the protocol for cultivation of a lawn composed of hybrid bermudagrass, bulbous, annual and perennial herbaceous plant species.The experiment was carried out on a mature (over 5 years-old) sward of hybrid bermudagrass on which eight bulbous species (geophytes) were planted and eight species of native forbs (wildflowers) were sown. Forbs that could coexist after two years with bermudagrass were B. perennis and G. molle. Concerning the bulbous species C. pulchellus, M. neglectum, G. nivalis and N. minor were suitable to be planted in a Bermuda grass. The presence of these species on a dormant bermudagrass turf improved the aesthetical quality and the diversity of the vegetation; as the studied species are able to attract pollinating insects therefore, support a habitat. Further studies will be required to test the most suitable forbs as a mix in combination with bulbous species
Zoysiagrass Cultivar Establishment Rate and Turf Quality in Central Italy
Zoysiagrass is a warm season grass native to Asia and South Pacific, adapted to the transition, warm-arid and warm-humid climatic zones. Nevertheless, large differences occur between species and genotypes of Zoysiagrass in establishment rate, adaptation to low temperature and winter injury. The objective of the study, carried out from July 2007 to November 2008 at the research station of Centre for Research on Turfgrass for Environment and Sports, University of Pisa, was to evaluate the differences in establishment rate and adaptation to the latitude of coastal Tuscany of 5 cultivars of Zoysia japonica, 2 cultivars of Zoysia matrella, Zoysia tenuifolia and 2 interspecific hybrids of Zoysia japonica × Z. pacifica. Establishment rate, turf quality and colour and linear stolon growth were assessed in the trial period. Results show fast turf establishment for Zoysia japonica 'El Toro' and 'De Anza' yet in fall 2007. In June 2008 all cultivars reach complete establishment except Zoysia japonica × Z. pacifica 'HT 210' and Zoysia tenuifolia, which delay until the end of summer. Highest turf quality was observed for both Zoysia matrella cultivars and for Zoysia japonica × Z. pacifica hybrids, while lowest was Zoysia japonica 'Zenith'. Fall colour retention drops at the end of December for all cultivars. Green-up starts at the end of February for all the cultivars, being the fastest Zoysia japonica × Z. pacifica 'Emerald', Zoysia japonica 'El Toro' and 'Victoria, and Zoysia matrella 'Zeon'. The research shows that both Zoysia matrella cultivars and Zoysia japonica × Z. pacifica 'Emerald' were able to quickly reach full ground cover like the fastest Zoysia japonica
