Abstract/Contents: | "Plant growth regulators (PGRs) are an important management tool for the enhancement of turfgrass color, uniformity, and environmental stress tolerance. Differential response to commonly used PGRs have been observed among bermudagrass cultivars. 'Iron Cutter' hybrid bermudagrass was released from Oklahoma State University in 2019 with significant improvements in drought, traffic, and cold tolerance; however, information regarding response to PGRs is limited. A field study was conducted at the Athens Turfgrass Research and Education Center in Athens, GA during the summer of 2021. Plant growth regulator treatments were initiated on 15 July 2021 and included trinexapac-ethyl (TE) at 96 or 126 g ai ha-1, prohexadione calcium (PC) at 235 and 460 g ai ha-1, and trinexapac-ethyl at 96 g ai ha-1 + prohexadione calcium (TE + PC) at 235 g ai ha-1 applied every two weeks. A non-treated check was included for comparison. Above-ground biomass and NDVI measurements were obtained every two weeks through the length of the trial. Biomass measurements for each treatment were compared to the non-treated check in order to convert to % growth regulation. All PGR treatments resulted in NDVI of 0.82 to 0.84 2 weeks after initial treatment (WAIT) compared to the non-treated check (0.78). Growth regulation (GR) was 36 to 37% for TE, 50 to 58% for PC, and 51% for TE + PC 2 WAIT. At 6 WAIT, the non-treated check NDVI was 0.64, while all PGR treatments exhibited NDVI of 0.71 to 0.76, with the highest NDVI (0.76) exhibited by the high rate of PC. GR at 6 WAIT was 28% in response to TE, 39 to 43% in response to PC, and 36% in response to TE + PC. Similar results were observed 10 WAIT. Greater regulation of Iron Cutter hybrid bermudagrass is observed in response to PC." |
