Final answer:
Bermudagrass is the turfgrass species with the glossiest underside, often chosen for its durability and low maintenance in warmer climates.
Step-by-step explanation:
In turfgrass management, the glossiness of grass can often indicate certain traits about its health and resilience. Bermudagrass is known for its thick, hardy blades which are indeed glossy beneath, especially when compared to grasses like Kentucky bluegrass, creeping bentgrass, and tall fescue. This glossiness can reflect light, reduce water loss, and sometimes deter pests. Bermudagrass is often chosen for its ability to withstand high traffic and heat, making it a popular choice for lawns, sports fields, and golf courses in warmer climates. It also has strong recuperative potential and requires relatively less maintenance.
The turfgrass species with the glossiest undersides of its leaves is Creeping bentgrass (c).
Creeping bentgrass has a shiny appearance on the underside of its leaves, which gives it a glossy look. This characteristic can help in distinguishing it from other turfgrass species.
Kentucky bluegrass (a), Bermudagrass (b), and Tall fescue (d) do not have the same level of glossiness on the undersides of their leaves.
