Sporoderm infrastructural and cytochemical modifications in cytoplasmic male sterile broad-bean (Vicia faba L.)

Jean-Claude Audran, Jacky Bouillot

Abstract


A comparative study of mature sporoderms of sterile and fertile pollen grains was performed using electron microscopic techniques. In sterile pollen grains, intine is lacking; ectexine sculpture is reduced and tectum is overlaid by membranous systems. Infratectal texture is compact and a sporopollenin granulous mass is obturing the aperture central region. Endexine reacts with proteins and acidic carbohydrates tests.
