Abstract/Contents:"Zoysiagrass (Zoysia spp.) is recognized for its low requirements for pesticide and fertilizer input, but Meyer (Z. japonica Steud.), the cultivar commonly used in the transition zone of the United States, is slow to establish. We evaluated new zoysiagrass progeny for stolon growth characteristics and rate of establishment and determined the relationship between stolon growth characteristics and coverage. 'Meyer', DALZ 0102 (a Z. japonica), and 18 progeny from crosses of 'Emerald' (Z. japonica x Z. tenuifolia Willd. ex Thiele) or a Z. matrella (L.) Merr. x Z. japonica were planted as 6-cm diameter plugs on 30.5 x 30.5-cm centers in 1.5 x 1.5-m plots in 2007 and as single 10-cm diameter plugs in 1.2 x 1.2-m plots in 2008 in Manhattan, KS. Data were collected weekly on number of stolons initiated per plug, stolon elongation, and number of stolon branches. Two researchers rated coverage visually near the end of each growing season. Rate of stolon initiation ranged from 2.2/week to 8.6/week. Elongation rate ranged from 18.8 to 65.1 mm/week. At 11 weeks after planting in 2007, four of 18 progeny had superior coverage to 'Meyer'; at 11 weeks after planting in 2008, 13 of 18 progeny had superior coverage to 'Meyer'. Rate of stolon initiation was positively correlated (P < 0.01) with zoysiagrass coverage (r = 0.66, in 2007; r = 0.94 in 2008); likewise, stolon elongation was positively correlated with coverage in 2007 (r = 0.52, P < 0.01) and 2008 (r = 0.53, P < 0.05). Stolon initiation or elongation could be used in short-term evaluations to predict rate of zoysiagrass coverage from plugs. Greater stolon initiation or elongation of experimental some zoysiagrass progeny makes them promising for alternatives to 'Meyer' for overcoming slow establishment rates."
