Abstract/Contents:"Growth and quality of creeping bentgrass often decline during hot summer. This study determined and compared responses of turf quality, growth and carbohydrate accumulation to heat stress in two creeping bentgrass cultivars, 'L-93' and 'Penncross'. Grasses were grown under two temperature regimes, 22/16 oC (day/night) and 35/25 oC (heat stress), in growth chambers. Turf quality, root viability, leaf photochemical efficiency (Fv/Fm) and chlorophyll content decreased while canopy minus air temperature increased under heat stress for both cultivars, to a greater extent for Penncross than L-93. The content of total nonstructural carbohydrates, fructan, starch, glucose, sucrose, and fructose in shoots and roots decreased under heat stress, with greater reductions for Penncross than for L-93. The results suggested that maintenance of carbohydrates accumulation could contribute to heat stress tolerance in creeping bentgrass."
