The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Cool-season turfgrasses are adapted to sub-temperate and temperate zones, growing actively during spring and autumn when soil temperatures range from $15^{\circ}\text{C}$ to $24^{\circ}\text{C}$.
Step 2: Detailed Explanation:
- Lolium perenne (Perennial Ryegrass): A classic $\text{C}_3$ cool-season grass. It germinates rapidly, develops a bright green canopy, and is widely used for overseeding warm-season lawns during winters in colder geographic zones.
- Zoysia japonica (Japanese Lawngrass): A warm-season turfgrass known for high heat tolerance and thick, slow-growing carpets of turf.
- Paspalum vaginatum (Seashore Paspalum): A warm-season turfgrass with high salinity tolerance, suited for tropical coastal zones.
- Buchloe dactyloides (Buffalograss): A warm-season grass native to arid/semi-arid regions, requiring minimal water.
Step 3: Final Answer:
The cool-season turfgrass is Lolium perenne.
