The average values of the stomatal index in the non - leaf organs in ca cereals were smaller than those of leaves . blanke put forward a new physiological process in fruit , ' fruit photosynthesis ' , and featured with lower stomatal frequency ( blanke , 1989 ) . the results here also showed that the significant lower stomatal frequency on non - leaf organs , indicating that the new physiological process might exist in these organs of cereals as well

Characterization of stomatal frequency , stomatal index and guard cell length stomatal characteristics appear to be related to variations in net photosynthetic rate and water - use efficiency ( sellers et al , 1996 ) . here , the stomatal frequency , the guard - cell length and the stomatal index of non - leaf organs were investigated comparatively between the ear and the leaf of wheat . the results showed that stomatal frequency of non - leaf organs is significantly lower than that of leaves , whereas the guard - cell length and stomatal index showed different variation patterns in both leaves and non - leaf organs
