Standardization of the tyrosinase test for identification of wheat varieties

Creator:: Matos, Marlene de
Abstract:: This study was undertaken to standardize and evaluate the tyrosinase test as a variety identification procedure for wheat. The potential value of the tyrosinase test lies in its ability to quantify the colored products, rather than relying on visual estimation as in the phenol test. The specific objectives of this...

Effect of production methods on quality of wheat seed

Creator:: Mathenge, Felix Njeruh
Abstract:: The objective of this research was to identify the optimum cultural practices for the production of the highest quality wheat seed in Oregon. The production methods included locations, irrigation, N levels and seeding rates. The seed quality factors studied were seed weight, bushel weight, protein content and seedling vigor. Foundation...

Presoaking and drying treatments to improve the performance of orchardgrass and bluegrass seed

Creator:: Haight, John Colson
Abstract:: The objective of this study was to develop a soaking and drying procedure to stimulate the germination and seedling emergence of orchardgrass (Dactylis glomerata L.) and Kentucky bluegrass (Poa pratensis L.) seed. Some of the physiological changes associated with the soaking and drying treatments were also studied. The seed was...

Physical characteristics of crownvetch (Coronilla varia L.) seeds associated with viability and hardseededness

Creator:: Garay, Adriel Edgardo
Abstract:: The use of crownvetch (Coronilla varia L.) as a forage crop might be increased considerably if seed with low hard seed content could be made available at reasonable cost. Since mechanical scarification damages a large percentage of crownvetch seeds, this study was initiated to find other ways of reducing hardseededness....

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...

Effect of seed protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Stimulation of bluegrass seed germination by soaking and drying treatments

Creator:: Onul, Taylan
Abstract:: The objective of this study was to develop a soaking and drying procedure to stimulate faster germination of Kentucky bluegrass (Poa pratensis L.) seed. The seeds were soaked in cheesecloth bags in nine chemical solutions. The effects of temperature and time of soaking and of aeration of the solution were...

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...
