Abstract. Pollen development in copper-deficient barley plants is highly irregular resulting in low and variable pollen fertility. The main cause of this sterility was found to be the abnormal development of the tapetum which becomes expansionary and invasive as the pollen develops. The ultrastructure of both tapetum and microspores is different from that of control material with irregularities of exine deposition, endopolyploidy of tapetal nuclei and an alteration of organelle composition being correlated with low fertility.
