Abstract/Contents:"Optimum temperatures for creeping bentgrass (Agrostis palustris Huds.) range from 20° to 30° C, considerably lower than experienced in Arizona during summer months. Genetic potentials for increased heat tolerance in this species are under investigation at The University of Arizona with support from the United States Golf Association Green Section. The ease of vegetative propagation from stolons provides a means for rapid screening and makes field use of identified superior clones feasible. Stolons possessing six nodes are excised, and leaves are removed from the lower four nodes. The stolons are placed in 240 ml of water in glass containers and exposed for two weeks to constant high temperatures (34° C to 40° C) in a growth chamber. At temperatures up to 34° C, stolons root rapidly and vigorously. Above 34° C roots per node, root lengths, root mass, and top growth are drastically reduced with each increase in temperature. Heat intolerant clones produce few or no roots above 36° C, while some heat tolerant clones root slightly above 40° C. Root growth of both clonal types is significantly increased by aeration, particularly at the high temperatures. The procedure used not only differentiates clones for rooting capability under heat stress, but also provides a means for laboratory study of aerification, genotype and temperature interactions important to efficient use of cool season grasses in warm climates. This technique should be useful with other stoloniferous species."
