WebJan 13, 2024 · Stomatal index is the percentage which the number of stomata form to the total number of epidermal cells, each stoma being counted as one cell. Stomatal index can be calculated by using the following equation: Stomatal Index = S x 100/E+S Where, S= Number of stomata per unit area E= Number of epidermal cells in the same unit area.
