Abstract/Contents:"Salt problems at turfgrass sites are becoming more common, and the effects of mowing management on salinity tolerance are not well understood. The current study was conducted to examine the effects of three mowing regimes on performance and physiological responses of 'Brilliant' Kentucky bluegrass (Poa pratensis L.) (KBG) to salinity stress. Sods of 'Brilliant' KBG were grown in containers in a greenhouse. Treatments included three mowing regimes (clipping twice weekly at 50 mm, three times weekly at 25 mm, and four times weekly at 13 mm) and four levels of irrigation water salinity (control, 3 dS m-1, 6 dS m-1, and 9 dS m-1). Data analysis showed that increasing salinity level resulted in reduced turfgrass quality, clipping yield, canopy net photosynthetic rate (Pn), leaf water potential (Ψ), shoot K+, and reduced K+/Na+ ratio for KBG under all three mowing regimes. Turfgrass quality reduction as a result of increased salinity appeared earlier and was more severe for KBG mowed at 13mm, four times per week, than for those mowed at 25 mm and 50 mm, three times and two times per week, respectively. Linear regression analyses predicted that turf quality of KBG that was mowed to 13 mm, 25 mm, and 50 mm will fall below the acceptable level of 6 when soil salinity reaches 5.2, 6.6 and 6.4 dS m-1, respectively. Furthermore, clipping yields and leaf water potential exhibited greater reduction for KBG mowed at 50 mm than that mowed at 13mm and 25 mm as irrigation water salinity increased. Therefore, we suggest that a moderate mowing height could improve the salinity tolerance of KBG under saline irrigation water treatment."
