Environmental and genetic factors affecting seed set in Dactylis glomerata L.

Creator:

West, David L.

Abstract:

Field, growth chamber, and greenhouse studies were carried out to evaluate factors that cause low seed set in Dactylis Glomerata L. The variety, 'Latar', and the parental clones of the variety, 'Pennlate', were studied in detail. Floral anatomy investigations indicated that 98 percent of Dactylis flowers opened at Corvallis in...

Selectivity and chemodynamics of 3,5-dibromo-4-hydroxybenzonitrile in winter wheat (Triticum aestivum L.) and coast fiddleneck (Amsinckia intermedia Fisch. & Mey)

Creator:

Schafer, David Eugene

Abstract:

Controlled environment chamber and laboratory studies were carried out to evaluate selectivity and chemodynamics of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) in winter wheat (Triticum aestivum L.) 'Nugaines', a tolerant species, and coast fiddleneck (Amsinckia intermedia Fisch. & Mey), a susceptible species. A comparison of ED₅₀ values, based upon reduction of whole plant growth,...
