Two types of turfgrasses, the warm-season and the cool-season, are widely used for covering the surface of athletic fields and golf courses. We investigated the microstructures of the leaf and root surfaces of Tifton419 as a warm-season grass and Kentucky bluegrass as a cool-season grass. The warm-season a grass had characteristic silica structures (silica body). They are speculated to be protectors against predators or to strengthen against mechanical stresses. While the leaves of the cool-season grass had characteristically scrobiculated micro structures in which air may be retained, we suggested that these pockets might insulate the plant from very low temperatures.
