چکیده
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 mg PBZ, and sand+ 15% zeolite+ 30 mg PBZ, and were irrigated with 0.24 (control irrigation), 3.4 and 6.4 dS・ m-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 …
