Formatted Abstract/Summary
Fine-textured hybrid bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] cultivars have
been widely used for golf putting greens and lawn bowls greens in warm-climate areas for more than 40 years. During
the past decade, the choice of cultivar for professional turfgrass managers has been expanded by a range of secondgeneration
hybrid bermudagrasses, which differ from the first-generation cultivars ‘Tifgreen’ and ‘Tifdwarf ’ in their
management requirements. In this paper, we present comparative morphological and developmental data for seven
cultivars (Champion Dwarf, FloraDwarf, MS-Supreme, Novotek, Tifdwarf, TifEagle, Tifgreen) grown in spaced plant
and sward experiments at Cleveland, Australia (27º32’S lat, 153º15’E long, 25 masl). The four ‘ultradwarf ’ cultivars
(Champion Dwarf, MS-Supreme, FloraDwarf, TifEagle) showed slower vertical extension and produced fewer
inflorescences than Tifdwarf, Tifgreen, and Novotek. However, in terms of the length of stolon internodes and their
overall rate of lateral spread, Champion Dwarf, FloraDwarf, and TifEagle were comparable to Tifdwarf; MS-Supreme
(with longer internodes) spread faster laterally, though slower than Tifgreen (which had the longest stolon internodes).
In unmown swards, the four ultradwarfs produced shorter leaves than Tifgreen, Tifdwarf, and Novotek, but only
Champion Dwarf produced significantly narrower leaves than Tifgreen, Tifdwarf, and Novotek, with TifEagle leaves
also significantly narrower than those of Tifgreen and Novotek. Minimum threshold temperatures for growth were
approximately 9° to 10°C (air temperature) and 15° to 16°C at 10 cm soil depth.
