A study of the SH and SS content levels during vernalization of
wheat was made. In order to carry out the study, a rapid analytical
technique was worked out which allowed fast sequential analyses of
the samples of wheat tissue.
Two techniques were used: a) an amperometric titration
method and...
Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...
Vernalization - the requirement of a period of low temperature to induce the transition from a vegetative to a reproductive state - is an evolutionarily and economically important trait in the Triticeae. The genetic basis of vernalization in barley (Hordeum vulgare subsp. vulgare), a model crop for the Triticeae, was...
California brome (Bromus carinatus Hook & Arn), is
considered an important weed infesting wheat and grass seed
fields in the Willamette Valley of Oregon. Field and
greenhouse experiments were conducted to study some
biological aspects to develop more efficient management
strategies.
A field experiment was conducted to determine the
effect...
Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...
The effect of low temperatures given at different times and duration
upon the time of bud burst, shoot elongation, number of needles
developed and needle length in Douglas-fir plants from the Oregon
Cascades and three coastal areas ranging from Washington to California
were determined. The plants were grown outside in...
Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...
Jointed goatgrass (Aegilops cylindrica Host) infestations in winter wheat (Triticum aestivum L.) production regions of the central and western USA result in severe economic losses in the wheat market. Field and greenhouse studies were conducted to determine the vernalization requirements of winter wheat, spring wheat, jointed goatgrass, and wheat by...
