Abstract/Contents: | "Plant growth regulators (PGR) have shown potential to reduce drought stress in turfgrass. However, most of the research had primarily focused on Trinexapac-Ethyl. The objective of this study was to evaluate the effects of several commercially available PGR on drought stressed bermudagrass (Cynodon dactylon L.). The study was conducted in Las Cruces (NM), from May to November of 2017 on Princess 77 bermudagrass mowed at 12 mm height. Two irrigations regimes were chosen: 75% ETos (normal watering) and 45% ETos (Drought conditions), in a complete randomized block design with 4 replications. The subplot treatments consisted of: Trinexapac-Ethyl (TE)(PrimoMaxx, Syngenta), Paclobutrazol (PA) (Trimmit2SC, Syngena), Flurprimidol (Flu)(Cutless50W, SePro) Prohexadione calcium (PCa)(Anuew, Nufarm), Flu +TE (Legacy, SePro), Flu+PA+TE (Muketeer, SePro), and an untreated control. Treatments were applied at the recommended label rate for bermudagrass, on a 28 days interval. Data collection consisted of turfgrass quality, digital image analysis for % green cover and dark green color index (DGCI), chlorophyll content and moisture readings. Additionally, root samples were collected at the end of the study to investigate the effects of PGR on root architecture. At 45% ET, Musketeer resulted in higher turfgrass quality compared to the control. Trinexapac-Ethyl increased DGCI compared to the plots at 75 and 45% ETos. Under 45% ETos TE, PA and PCa increased chlorophyll content compared to Flu+PA+TE and untreated control. Additionally, under drought conditions, PCa, Flu, PA and Flu+PA+TE resulted in higher moisture content compared to control and Flu+TE. These results show that PGR in general increased bermudagrass turfgrass quality under drought conditions, however some appear to perform better than others. Additional information is needed on long term effects of PGR use for drought tolerance." |
