Trinexapac-ethyl Rate Response Data

The data presented is from an experiment evaluating the response of bermudagrass off-types and cultivars to increasing rates of the plant growth regulator, trinexapac-ethyl.  Rates included 0, 1.6, 3.3, 6.6, 13.1, 26.3, 52.6, or 105.2 g active ingredient per hectare.  Grass samples included three, morphologically distinct off-type grasses and bermudagrass cultivars Champion, MiniVerde, and TifEagle.  The response variable is clipping weight expressed as mg per square cm.  The experiment was a completely randomized design with grass sample and trinexapac-ethyl rate in a factorial treatment arrangement.  Clippings were harvested 7, 14, 21, and 28 days after treatment and was included in the analysis as a repeated measure.
