Book Description
Soybean (Glycine max L.) seed yield, composition, and quality can be negatively affected by environmental stresses during the growing season and harvest. The central hypothesis of this thesis is that soybean seed testing techniques, i.e. testing media, need to be adjusted for seed moisture content, production environment, and seed composition, as these factors alter the measured germination in laboratory tests. Water and nutrient deficit during pod filling usually lead to poor yields by reducing seed set, increasing seed abortion, and reducing seed size. While maturation drying and the acquisition of desiccation tolerance are critical physiological processes that help orthodox seeds (seeds from species that can be stored at low moisture content) survive periods of unfavorable conditions for germination, the warm and dry conditions during harvest can often over-dry seeds. Extremely dry seeds experience stresses during imbibition which are likely to result in imbibitional damage and seedling abnormalities. The production environment can also lead to composition differences within seeds and may play important roles in imbibitional injury. Being able to accurately evaluate seed germination will be crucial regardless of seed composition, production environment, and, inherent genetic differences. Seed analysts must consider soybean seed composition and seed moisture, and, their interaction with testing media to avoid inconsistent test results within and among seed testing laboratories.
