Abstract/Contents:"A decrease in available photosynthetically active radiation caused by shade can be detrimental to turfgrass growth, development, and quality. Shade is rarely constant and instead fluctuates throughout the day. Some areas may be shaded for a partial day whereas others may be continuously under shade. Morning shade is reported to be more detrimental to cool-season turfgrasses under field conditions but this result is somewhat inconclusive. The objective of this study was to determine the effect of temporal shade on photosynthesis of creeping bentgrass. Plugs of creeping bentgrass (Agrostis stolonifera L.) were established in a 2.5 m diameter conetainer containing sand. Grasses were fertilized with 19 kg N/ha per month using Peters Professional 20-20-20 (The Scotts Company, Marysville, OH) every week and grasses were mowed every three days and clippings were collected. After a month, the conetainer were be kept under full sun, morning shade, and afternoon shade with 6 replications of each treatment. The greenhouse conditions was be maintained at 35/25 ┬░C day/night temperature. Photosynthetically active radiation (╬╝mol m-2 s-1) was measured using a quantum light sensor (Spectrum Technologies, Inc., Plainfield, IL) and data were recorded every 15 min using Watchdog 1000 (Spectrum Technologies, Inc., Plainfield. Light response curves were created with an auto program that adjust photosynthetic photon flux density from 2000 to 0 D*mmolm-2s-1. Light response curve data will be discussed."
