A STUDY OF THE RELATION OF TRANSPIRATION TO THE SIZE AND NUMBER OF STOMATA

Considerable work has been done in determining the quantity of water lost from various plants under various conditions. Several extensive investigations have been conducted with a view of determining stomatal values for various species. Although several important researches have been conducted concerning the stomatal regulation of transpiration, very little has been done on the amount of transpiration in relation to the size and number of stomata per unit of transpiring surface. It was my aim to determine whether any relation exists between the amount of transpiration and the number of linear units of stomatal aperture per unit of leaf surface.
