Table 3. The number of vascular bundles, diameter, and bleeding intensity of the neck internode in rice grown in different potassium levels.
| Potassium level |
Line | HD | FS | ||
|---|---|---|---|---|---|
| Large vascular bundle (No culm-1) |
Small vascular bundle (No culm-1) |
Diameter (mm) |
Bleeding intensity (mg h-1) |

| K0 | MH63(Cry1C*) | 13.7 a | 21.4 b | 2.01 b | 0.50 b |
| MH63 | 14.7 a | 25.2 a | 2.22 a | 0.85 a | |
| K1 | MH63(Cry1C*) | 14.5 a | 23.6 b | 2.06 b | 0.62 b |
| MH63 | 15.1 a | 25.2 a | 2.18 a | 1.14 a | |
| K2 | MH63(Cry1C*) | 12.9 a | 21.2 b | 1.94 b | 0.71 b |
| MH63 | 13.5 a | 25.7 a | 2.03 a | 0.86 a | |
HD: Heading stage; FS: Filling stage. Values followed by different letters are significantly different between the two rice lines grown in the same potassium levels at p<0.05.
