Abstract:: 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...
