| Abstract/Contents: | "Recently developed cultivars of creeping bentgrass (Agrostis stolonifera L.) possess higher shoot densities. The increased shoot densities allow these cultivars to better resist invasion from annual bluegrass but little data exists regarding differences in the recuperative potential among cultivars of creeping bentgrass. The objectives of this research were to determine the effects of shoot density on the recuperative potential among cultivars of creeping bentgrass. The recuperative potential of twenty three cultivars of creeping bentgrass and a single cultivar of colonial bentgrass were evaluated in 2009 and 2010 by creating simulated divots and allowing the cultivars to recover via stolon growth. The cultivars were maintained under conditions designed to mimic a golf course fairway and divot recovery was evaluated semiweekly by using digital image analysis techniques. In 2009, all cultivars had divot recovery rates statistically similar with 'Penncross' although improved cultivars did exhibit greater shoot densities. In 2010, the cultivars 'SR 1150', 'T- 1', and 'Kingpin' had divot recovery rates significantly slower compared with 'Penncross'. Shoot density was inversely proportional to divot recovery rate suggesting that a greater number of shoots may hinder the ability to recuperate from injury. Stability analysis indicated that the cultivars 'Alpha', 'Crenshaw', 'LS-44', 'Penn A-4', 'Penncross', 'Pennlinks II', 'Putter' and 'Southshore' exhibited consistent, above average lateral spread across the two years in this study. The increased shoot density of newer cultivars may slow the recuperative potential of creeping bentgrass and should be considered when selecting cultivars for specific use areas." |
