Final answer:
The statement regarding bermudagrass as the primary turfgrass on sports fields in the South and Southwest is true, as it suits the climate and wear demands of the fields.
Step-by-step explanation:
The primary turfgrass on sports fields in the South and Southwest is indeed bermudagrass, making the statement true. Bermudagrass is widely appreciated for its durability and resilience, which are qualities that make it an excellent choice for sports fields where the grass regularly experiences high traffic and needs to recover quickly from wear and tear. Bermudagrass also has a high tolerance for heat, which is typical of the Southern and Southwestern climates. Furthermore, bermudagrass establishes quickly, can withstand close mowing, and provides a fine-textured playing surface that is ideal for sports.
In addition, considering other educational content related to the subject, the Southeastern United States was indeed an independent center for plant domestication, confirming that the first statement is true.
