Abstract/Contents:"Salinity tolerance of five Kentucky bluegrass (KBG) (Poa pratensis L.) cultivars, Mystere, BAR VV 0709, Bariris, Rugby II, and Bewitched, were tested to determine germination and seedling growth. Twenty pure live seeds of each cultivar were placed in petri dishes and hydrated with 7 mL of MgSO4 at 0.0 (deionized water), 1.6, 3.6, or 9.0 dS/m at 25/15°C with 8/16 h photoperiod cycle for 3 weeks. In another test, seeds were planted in pots to determine seedling responses to the same saline solutions. Pots were watered daily with 70 mL of the saline solutions and seedling responses (number of seedlings and tillers and tissue dry weight) and soil salinity were determined 45 days later. All KBG cultivars showed similar germination rate (average germinated seeds = 17.2) during germination regardless of MgSO4 levels. Soil salinity increased from 0.3 to 5.6 dS/m and 0.1 to 4.2 dS/m in Study I and II, respectively, as MgSO4 increased from 0.0 to 9.0 dS/m. Seedling growth decreased as MgSO4 levels increased. All five KBG cultivars responded similarly to saline solutions, except in Study II where seedling numbers were the highest in 'Rugby II' and 'Bariris' (average = 11.8) and lowest in 'BARVV0709' (3.0) at 1.6 dS/m. Results revealed that KBG seedling growth is more sensitive to high salinity levels than germination."
