Several studies have demonstrated that the establishment of bermudagrass [ Cynodon dactylon (L.) Pers.] in transition zones should take place as early as possible in spring in order to avoid damage in the winter of the first year. To define the base germination temperature of some commercial common bermudagrass cultivarsin Europe, a laboratory study was conducted fromApril to May 2013 at the Agricultural Research CouncilLaboratory of Tavazzano (Lodi). Ten bermudagrass cultivars: 'Gobi' , 'Sunbird' , 'SR9554' , 'Princess77' , 'Yukon' , 'Riviera' , 'Transcontinental' , 'Casinò Royal' , 'Savannah' , and 'La Paloma' were tested at alternating temperatureregimes 0/10 °C, 5/15 °C, 10/20 °C, 15/25 °C to assess final germination percentage and seed vigour through calculation of the Germination Rate Index and Corrected Germination Rate Index. This study shows that seeded bermudagrass cultivars havesignificantly different germination capacity at the testedtemperatures. In addition, findings indicate that seededbermudagrass can even germinate at temperatures of 10/20 °C, corresponding to an average temperature of 15 °C. Among tested cultivars 'Riviera' showed the slowest germination.
