| Abstract/Contents: | "Following incidence of winter kill, creeping bentgrass (Agrostis stolonifera L.) is often the only seed option for early spring establishment on golf course putting greens. Little information is known about the effects of light and temperature on bentgrass germination. Two laboratory studies and one field study were conducted to assess germination of 75 samples of bentgrass at 10°C in vitro and 24 samples in the field. In both laboratory studies, 100 seeds of each sample were placed on a square dimpled blotter paper moistened with 5ml de-ionized water and placed in a petri dish. Plates were incubated at 10°C in either complete darkness or on an 8/16 hour light/dark cycle. Germinated seeds were counted every 1 to 3 days for 28 days. Seeds were considered germinated when coleoptile emergence was visible to the naked eye. Studies were arranged as a completely randomized design with three replications and were repeated twice. The field study was initiated at the Joseph Valentine Turfgrass Research Center, University Park, PA in Spring 2017 and 2018 based off a growing degree day model. Bentgrass samples were seeded with a shaker jar at a rate of 73 kg pure live seed ha-2 mixed with Milorganite (342 kg per ha-2) into a putting green previously treated with Glyphosate to simulate winterkill. Prior to seeding the area was core cultivated and vertically mowed in two directions. The study was arranged as a randomized complete block design with 4 replications. All data were analyzed using the SAS University edition MIXED Procedure. Data will be added prior to submission." |
