A greenhouse experiment was conducted to study the effect of zeolite and drench application of paclobutrazol (PBZ) on the salt stress response. Kentucky bluegrass (Poa pratensis L.) turfs were grown in boxes filled with sand (100%), sand + 15% zeolite, sand + 30 ㎎ PBZ, and sand + 15% zeolite + 30 ㎎ PBZ, and were irrigated with 0.24 (control irrigation), 3.4 and 6.4 dSㆍm?¹ saline water daily for 6 months in greenhouse condition. Saline water reduced TQ, TFW, TDW, CY, PR, transpiration, SC, ME, and WUE, compared to control condition, Paclobutrazol and salinity treatments reduced growth and development, progressively produced plant that were too small especially at the highest saline concentration. Amendment of sand with zeolite increased TQ, TFW, TDW, CFW, CDW, PR, transpiration, SC, ME, and WUE during both second and third months of the experiment at both salinity levels. The beneficial effects of zeolite on turf quality and other parameters diminished 3 months after treatment. Amendment of sand with zeolite reduced leaching of Na and K but increased leaching of Ca?? and Mg??. Using zeolite in medium increased SAR value compared to control. Results indicated that amending with zeolite may buffer soil solution Na+ concentration in short-term. In the long-term, however, a substantial amount of Na? may be retained concurrent with Ca?? and Mg?? exchange, thereby increasing sodicity and salinity problems. Furthermore, results indicated that PBZ can reduce salinity effect via reducing the availability of salt ions in the medium.
