【Abstract】 Distribution of stomata in both epidermies of rice leaves was regular.Stomatal frequency in both epidermies of rice leaves decreased with leaf locations.Significant differences among rice types or varieties were found about Stomatal frequency in both epidermies of all leaf locations or between adaxial and abaxial epidermies.Stomata of leaf sheath distributed among epidermal cells,Stomatal frequency in abaxial epidermies decreased with leaf locations,presented a crosswise double peaks curve.From upper part to lower part,Stomatal frequency in one leaf sheath decreased.更多还原
