Book Effect of Seed Moisture Content Seed Composition and Testing Media in Soybean Glycine Max L Germination Tests

Download or read book Effect of Seed Moisture Content Seed Composition and Testing Media in Soybean Glycine Max L Germination Tests written by Nathan Andrew LeVan and published by . This book was released on 2006 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Aged Soybean Glycine Max L Merrill Seeds

Download or read book Aged Soybean Glycine Max L Merrill Seeds written by Soja Sekharan and published by . This book was released on 2005 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The physiology of seed deterioration was studied with accelerated and naturally aged soybean (Glycine max (L.) Merrill) seeds. Accelerated aged (AA) seeds of "Flint" were aged for 0, 24, 48, 72 and 96 h at 41 and 43°C and 100% relative humidity. Seedling vigor analyses for vigor index and growth were analyzed with scanned images of 3d-old seedlings. Embryonic and cotyledonary tissues from 3d-old seedlings were used for mitochondrial isolation and specific enzyme activity studies. In cotyledonary tissues, respiratory activities were lower than embryonic tissues. Antioxidant activities of glutathione peroxidase were at high levels in accelerated aged embryonic tissues. Increased oxygen uptake measurements with reduced b-nicotinamide adenine dinucleotide and reduced oxidation with succinate as substrates indicated respiratory capacities of isolated mitochondria. Oxygen uptake with both these substrates was higher in embryonic mitochondria than from cotyledons. These studies emphasize that specific enyme activities in mitochondria increased in embryonic tissues and decreased in storage tissues of soybean seeds subjected to AA treatment. Transmission electron microscopy of the ultra-structure of mitochondria from embryonic tissues of aged seeds indicated damage to inner membranes. Seedling vigor was studied with an automated imaging technique called the Seedling Vigor Imaging System (SVIS®). Following AA, the aged seeds of "Flint" were treated with a seed coating fungicide, Rival® [Captan N-Trichloromethylthio-4-cyclohexene-1,2-dicarboximide)], to reduce storage fungal infection. Germination, dead seed percentages and SVIS® parameters such as growth, vigor index and uniformity were highly significant for AA duration, temperature and Rival® treatment. Independent experiments with "Kottman" seeds were tested with SVIS® for seedling vigor effects on standardized germination testing protocols such as alternating temperatures of 20-30°C and 25°C, water content in germination papers and time of scan. Intra- and inter-seed lot variability of seed lots was also evaluated. These studies emphasize that mitochondrial activities differ in tissues of aged seeds and SVIS® could be used for seedling vigor testing in soybean.
