Using light microscope (LM) it was found very difficult to distinguish the ektexine (outer sculptured layer of exine) pattern of maize (Zea mays L.) pollen grains from that of its wild relatives teosinte (Euchlaena mexicana Schrad.) and tripsacum (Tripsacum spp.). At the magnifications obtained by LM, the pollen grain ektexine is faintly granular or netted. By the use of electron microscopy, however, it is possible to characterize their pollen ektexine patterns.For scanning electron microscopy (SEM) acetolysed pollen grains were used. After acetolysis the pollen samples were washed several times in glass-distilled water to remove traces of acids. Each sample was dispersed in a drop of distilled water placed on specimen holders.
