Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...
Rate of emergence is an important character for stand
establishment. Ability of wheat seeds to germinate and
emerge rapidly under different climatic conditions may be
regulated by physical and/or physiological characteristics.
Seeds of 26 wheat varieties representing five classes
were produced in two different environments (Moro and Corvallis,
OR). Seed...

Germinating seeds often encounter stress conditions
of temperature, moisture and oxygen in the field.
Germination tests conducted under these stress conditions
in the laboratory might be methods of differentiating high
and low vigor seeds.
The objectives of this study were to (1) determine
if these stress conditions reduce germination performance...
The occurrence of seed-producing wheat x jointed goatgrass hybrids in infested wheat fields suggests the possibility of gene flow between the two species. This study investigates 'Madsen' wheat x jointed goatgrass F₁ and reciprocal backcross derivatives produced in experimental field plantings. Electrophoresis of the high molecular weight (HMW) glutenin seed...
