Abstract
Abstract High temperatures during simulated shipping were more consistently injurious to ‘Merion’ Kentucky bluegrass ( Poa pratensis L.) sod than other factors tested. Sod produced with increasing amounts of nitrogen had increased rates of temperature rise. Higher nitrogen levels also increased respiration, percent leaf kill, and ethylene production. There was no consistent effect of 6-benzylamino purine (BA) on sod storage life. Mowing to 2 cm prior to harvest reduced the amount of living tissue, causing lower temperatures, lower respiration rates, and less sod injury. Root production after sod transplanting was greatest from sod grown with 0 and 100 kg/ha of nitrogen fertilization and decreased with higher nitrogen rates.
