Abstract/Contents: | "The need for drought resistant turfgrass is increasing due to the decreasing availability of water for landscape irrigation. However, shaded lawns normally need less irrigation water than the lawns under open air, and the drought resistance of different turfgrass cultivars may differ under shade. A greenhouse study was conducted to determine the relative drought tolerance of four turfgrasses under shaded conditions. The genotypes studies were 'Falcon IV' tall fescue [Lolium arundinaceum (Schreb.) Darbysh], 'Latitude 36' hybrid bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy], and 'Meyer' and 'El Toro' zoysiagrass (Zoysia japonica Steud). Plants were grown in 15-cm diameter lysimeters and allowed to fully establish before the onset of drought. Each cultivar was subjected to two irradiance levels for 8 weeks prior to the onset of drought: low light (55% nominal shade fabric) and high light (ambient greenhouse conditions with supplemental artificial lights). Within each irradiance level, each genotype was subjected to either well-watered conditions (daily replacement of evapotranspiration) or drought stress (no irrigation). Differences were observed among genotypes for normalized difference vegetation index (NDVI), canopy temperature, leaf firing, daily water use rate, roots distribution, and relative water content. Cultivars under shade showed slower drying and firing during the study. Results from two experiments will be reported." |
