Summary The Juglans regia x Juglans nigra hybrid cannot be obtained because of stable interspecific barriers. We have analyzed and described various morphological and biochemical characters in J. regia and J. nigra pollen: differences in the mineral composition, polysaccharide reserves, wall ultrastructure and protein pattern of soluble cytoplasm, membranes, and cell-wall fractions. The absence of a glycoprotein fraction in the wall of J. nigra suggests that the regulation of critical steps in the interspecific matching with female tissues could be affected.
