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.

This book was released on 2011-07 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean seed viability and vigour are some of the major constraints in soybean production because considerable amount become downgraded due to improper storage. The germination potential is very short lived in soybean as compared to other oil seed crops and is often reduced prior to planting time. This loss of germination is much more acute under tropical conditions. Seed deterioration is one of the basic reasons for low productivity in soybean. Based on conditions under which this work was conducted, it can be concluded that soybean seed undergo deterioration with the rate dependent on storage temperature and crop species. Storability among storage materials varied with bottle storage giving the better storage. Also, there were variations among soybean varieties on viability and vigour as well as among the environmental conditions. However, cold storage gave the best in preserving viability and vigour of soybean seed. The result of this work will give the farmers researchers and seed producers a better option of material and environmental condition to be used for storing seeds especially in the tropics, because seeds are frequently stored from one year to another.
