SDS-PAGE of seed proteins for identification of varieties and species of ryegrass (Lolium spp.)

Creator:: Ferguson, Janet M.
Abstract:: The number of varieties of ryegrass (Lolium spp.) has increased greatly in recent years. An accurate and rapid laboratory technique to identify these varieties would benefit the consumer as well as protect an organization's Plant Variety Protection rights. There is also a need for a technique to complement the seedling...

Effect of nitrogen fertilization of wheat (Triticum spp.) on chemical and biochemical composition and performance of seeds

Creator:: Garay, Adriel Edgardo, 1945-
Abstract:: High protein wheat seeds frequently perform better than low protein seeds of the same variety. Protein content of seeds can be increased by management practices, the most important of which is rate and timing of N applications. The purpose of this study was to determine the chemical, biochemical and physiological...

Laboratory methods for wheat variety identification

Creator:: Ait Amer Meziane, Aomar
Abstract:: There is an increasing need for development of laboratory identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field testing methods based on morphological differences were used satisfactorily. These tests require several months to complete...

Grass seed quality in relation to time of windrowing

Creator:: Dübbern de Souza, Francisco Humberto
Abstract:: This study was undertaken to obtain information on the quality of grass seed when windrowed at the high moisture levels necessary for obtaining maximum yields. A secondary goal was to monitor moisture and temperature fluctuations in the windrow and to relate their effects to development and deterioration of the seed....

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Effect of sheep grazing on subterranean clover (Trifolium subterraneum L.) seed production

Creator:: Steiner, Jeffrey John
Abstract:: Subterranean clover (Trifolium subterraneum L.) seed production practices in Oregon are different from those in Australia. There, seed is produced on fields which are managed primarily for forage. In Oregon, seed fields are managed for seed as the primary product and forage is of secondary concern. Some sheep grazing is...

Effect of moisture stress on yield and quality of winter wheat seed

Creator:: Assuncao, Marcos Vinicius
Abstract:: Two experiments were conducted to determine the effects of moisture stress on physiological changes that occur during the vegetative and reproductive stages of the wheat (Triticum aestivum L.) plant, and to relate these effects to seed yield, quality and performance. In a field experiment, different levels of moisture stress were...

Endosperm morphogenesis in wheat (Triticum aestivum L.)

Creator:: Huber, Andrew Gail, 1944-
Abstract:: Wheat endosperm morphogenesis was studied by light microscopy during the entire growth period of anthesis to maturity. Four developmental stages have been described in this thesis: (1) double fertilization, (2) formation of the lower endosperm cells, (3) termination of nuclear divisions, and (4) initiation of protein bodies. The first manuscript...
