Abstract/Contents:"Ethephon is an ethylene-evolving plant growth regulator that has been shown to alter the growth habit and morphology of several plant species. The effects of ethephon on the morphology of turfgrass species have been poorly defined. The objective of this study was to determine how ethephon treatment affects leaf blade, sheath and internode lengths of eight common turfgrass species. Bermudagrass, creeping bentgrass, fine fescue, Kentucky bluegrass, manilagrass, perennial ryegrass, tall fescue and zoysiagrass were grown in the greenhouse on a Nicollet soil. Plants were evaluated for 12 weeks after an application of 2821-ppm ethephon and were compared to an untreated control. Application of ethephon decreased leaf blade length of all the grasses observed, but at different times and to varying degrees. Ethephon also affected sheath and internode lengths to differing degrees in a species dependent manner. Ethephon effects were most pronounced on Kentucky bluegrass and fine fescue, which displayed reductions in leaf blade length of 37% and 53% respectively, and produced expanded internodes, whereas the other species had varying morhphological differences. Ethephon affects the morphology of grasses, although observed species exhibited a differential response to ethephon application."
