Abstract:The penetration into soybean (Glycine max.) seed coat at physiological maturity (R7) by Alternaria sp. was studied using scanning electron microscopy. The fungus penetrated seed coat tissues either by direct penetration through the cuticle or through the micropyle. Other routes through which this pathogen may enter the seed include pits, where the seed coat is weak or through the complex hilum tissues. The micropyle of hard-seeded types of soybeans tend to be closed. Variation in structural seed coat characteristics may be used in breeding for resistance to seed pathogens.
