Summary

The sieve-plate pores of sieve elements in leaf veins of Hordeum vulgare, fixed in glutaraldehyde with postfixation in osmium tetroxide, were lined by the plasmalemma and variable amounts of callose. All pores were filled with endoplasmic reticulum, which was continuous from cell to cell. Mature sieve elements lacked P-protein.
