Abstract/Contents:"Annual bluegrass (Poa annua) golf course putting greens are prone to winterkill in northern regions. Previous investigations indicate a decline in annual bluegrass crown carbohydrate contents during dormancy and winter stresses like ice encasement. The objectives of this field and growth chamber study were to evaluate whether increasing the mowing heights in September promote higher carbohydrate content and winter recovery. Field plot mowing heights were equivalent during the summer at 0.125 in. Mowing treatments started in the first week of September in 202/2022 with 3.18, 3.81, 4.45, and 5.08 mm ending in early November 2021/2022.The treatments were incrementally increased every week during fall acclimation. During the fall acclimation of 2021/2022 and spring de-acclimation 2022/2023 periods NDVI was recorded. The 10.16 mm turfgrass plugs were taken in March 2022/2023 from the field and moved into growth chamber to undergo a second winter treatment where they were under ice encasement in the growth chamber for 0 and 40 days. After the ice encasement period, total non-storage carbohydrates (TNC) were analyzed. Fall and spring NDVI values were positively associated with higher mowing heights. Ice encasement recovery rates were enhanced by fall mowing height increases. TNC was not influenced by mowing height but was influenced by duration of ice encasement. Increasing mowing height of annual bluegrass putting greens during fall acclimation may improve annual bluegrass spring recovery and resilience to ice encasement but further research is needed to understand the mechanism associated with changes in recovery."
