Observations were made on the morphological changes of stomata and hairs of faba bean (Vicia faba L.) pods accompanying the development process by means of scanning electron microscopy on indigenous varieties of Finland (A) and (B) Japan and the new "topless" mutant lines of ICARDA (C). Although changes in stomatal density were approximately equal, they were least on C. The density of pod hairs on C, however, was greater than on the others throughout development. Moreover, the percentage of broken hair in C was stable in contrast to A and B, which increased severely with advancing development. Thus, the behavior of stoma and hair, especially the latter in C, seemed to play a specific supplementary role for dry matter production
