Stomatal characteristics of rice leaves with different Si method applications at 55 and 75 DAT.
| Treatment | Number of stomata per field of view (FOV) | Stomatal diameter (μm) | Stomatal width (μm) | |||
|---|---|---|---|---|---|---|
| DAT | ||||||
| 55 | 75 | 55 | 75 | 55 | 75 | |
| Control | 4b | 46b | 12.00a | 8.02b | 2.06b | 4.06b |
| Topdressing | 5b | 57a | 12.18a | 17.40a | 2.36a | 4.08b |
| Foliar spray | 8a | 47b | 10.80a | 17.40a | 2.48a | 5.63a |
| LSD (P=0.05) | 2.11 | 11.96 | 1.81 | 6.06 | 1.79 | 1.53 |
| CV | 8.63 | 2.40 | 5.50 | 8.32 | 5.19 | 9.10 |
Mean values followed by the same letters within a column are not significantly different at P ≤ 0.05 by the LSD test. DAT: days after transplanting; CV: coefficient of variation. Number of stomata (FOV) was counted at magnification 1000x.
