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 ()	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 by the LSD test. DAT: days after transplanting; CV: coefficient of variation. Number of stomata (FOV) was counted at magnification 1000x.
