Kentucky Bluegrass has greater heat resistance than Annual Bluegrass.

Explanation:
Heat resistance in turfgrass means a grass’s ability to stay green and keep growing when temperatures rise and water may be limited. Among cool-season grasses, Kentucky bluegrass generally handles hot, dry conditions better than annual bluegrass. This is related to its deeper, more robust root system and overall tolerance to heat stress, which helps it maintain photosynthesis and color longer into the summer. In practice, annual bluegrass tends to brown out or go dormant more quickly under heat and drought, whereas Kentucky bluegrass holds up comparatively better. So, the statement that Kentucky Bluegrass has greater heat resistance than Annual Bluegrass is true.
