  		Fig. 3. Aerenchyma formation of creeping bentgrass roots in response to 21 d of waterlogging. WL-15, WL-5, and WL-1 represent waterlogging (WL) at 15, 5, and 1 cm below the soil surface, respectively. A, B, C, D represent the drained control, WL-15, WL-5, and WL-1 of L-93, respectively. E, F, G, H, represent the drained control, WL-15, WL-5, and WL-1 of Penncross, respectively. Images of A to F are at 500x; image of G is at 750x; and image of H is at 600x. Arrow indicates aerenchyma. Bar = 20 µm.

  		Fig. 4. Mitochondrial ultrastructure of creeping bentgrass roots in response to 21 d of treatment. WL-15, WL-5, and WL-1 represent waterlogging (WL) at 15, 5, and 1 cm below the soil surface, respectively. A, B, C, D represent the drained control, WL-15, WL-5 and WL-1 of L-93, respectively. E, F, G, H, represent the drained control, WL-15, WL-5 and WL-1 of Penncross, respectively. All images are at 30 000x. Bar = 0.5 µm.
