| Abstract/Contents: | "Utilization of simultaneous screening for root extension and heat resistance may increase development of cultivars with broad stress resistance. This study was undertaken to develop a rapid screening technique to determine heat resistance and root extension among Kentucky bluegrass (Poa pratensis L.) cultivars. The root and rhizome systems of nine Kentucky bluegrass cultivars were submerged in water heated to 57, 58, 59, or 60 C for 30 minutes. Vigor ratings during recovery and percent decline in rooted shoot numbers indicated the cultivars Midnight and Adelphi had more heat resistance, with the cultivars Fylking and Nugget showing decreased vigor after exposure to heat stress. The same nine cultivars were grwon in polyethylene flexible tubes, 600 mm in depth, to examine rooting potential. The cultivars Wabash, America, and Midnight had the longest root extension with Bronco, Fylking, Nugget, and Huntsville having the shortest root extension. Midnight, which exhibited both high heat resistance and long root extension in these tests, is ranked as having high drought tolerance in the 1990 NTEP field trials, suggesting the use of the heat screening and root extension techniques employed here could be used to hasten progress in selection." |
