Interpretive Summary:

Technical Abstract: Biotic and abiotic processes determine soybean seed quality. Regulating these factors determines the quality of the seed; many processes that destroy seed quality can be controlled through genetics by the introduction of traits from germplasm. Before harvest, the pod is the first line of defense in the preservation of seed quality. The stomata are natural openings for microorganism penetration and the water permeability of the mature pod regulates the quantity of water that reaches the enclosed seed. The mature seed coat is the primary line of defense. Seed coat pores, micropyle, and hilum are natural openings for microorganism penetration. An impermeable seed coat inhibits water from reaching the enclosed embryo. It is the purpose of this talk to present the anatomy and morphology of the soybean pod and seed and discuss how variation in structure and morphology can control seed deterioration.
