| Abstract/Contents: | "A greenhouse (GH) and a field drought (FD) study were conducted at the University of Florida in July 2012 and September 2013 (GH studies) and May 2013/14 (field studies) to examine the rooting characteristics of several turfgrass species under water limited (DD) conditions. Sixteen warm season turfgrass genotypes of bermudagrass (CB), St. Augustinegrass (ST), Zoysia japonica (ZJ) and Zoysia matrella (ZM) from commercial sources and the UF turfgrass breeding program were studied. The objective of these studies were to examine root architectural differences between species under DD. Partial dry down was imposed in the GH whereas irrigation was halted for 21 days in the FD. In the GH, the root surface area (TRSA), fine root length (FRL), and maximum root depth (MRD) were higher for ST and CB species and BA336 (ZM) and 5269-24 (ZJ) genotypes within respective species. In the FD, CB had more uniform root distribution at lower soil depths approximate (47-48%) in comparison to ST (19-29%), ZM (6-10%) and ZJ (7-11%) species. Overall in both study years at the 30-90 cm depth, CB had higher TRL, TRSA, FRL, and RP during DD in comparison to ST, ZM 16 and ZJ species. In another study (January-November, 2011 and January-December 2012/2013), the effect of mowing height on seasonal rooting variation of 'Floratam' and 2012/2013 for 'Tifway' were evaluated. For Tifway, the 6.4 cm mowing height produced greater root growth compared to a 3.8 cm mowing height in 2012. In 2013, 1.3 and 3.8 cm had less root growth compared to 6.4 cm mowing height. For Floratam, the 10.0 cm mowing height produced greater root growth compared to the 5.0 cm mowing height. However, 7.6 cm and 10.0 cm as well as 7.6 m and 5 cm mowing height had similar root growth relative to time of the year. Information on differences between species under DD could be utilized as an approach for reduced water use in landscape turf. Similarly, the knowledge of seasonal variation in root growth as affected by different mowing heights could be utilized for fertilizer and irrigation management of Florida's home lawns." |
