It is important to understand how roots respond to temperature because it can affect root and relative growth rate, and in species with roots sensitive to temperature change, growth can be affected negatively. In this study, two species of grass were tested, one whose roots were more heat-sensitive and one whose roots were not. This was to see if species with heat sensitive roots would be affected greater than species whose roots are not heat sensitive. A. scabrais a known grass that thrives at very high soil temperatures, while A. stoloniferais a high-temperature sensitive grass grown in cool climates.
