Bioherbicide use of plant defensive compounds in meadowfoam seed meal

Creator:: Intanon, Suphannika
Abstract:: Meadowfoam (Limnanthes alba Hartw. ex Benth) seed meal (MSM), a by-product of meadowfoam oil extraction, has a plant defensive compound known as glucosinolate glucolimnanthin (GLN). Myrosinase enzymes present in soil microbes and meadowfoam seeds can convert GLN to glucosinolate breakdown products (GBPs), which demonstrate herbicidal activity and have the potential...

Nutrient management and cycling in grass seed crops

Creator:: Horneck, Donald Arthur
Abstract:: Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:: Bedoshvili, David
Abstract:: Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...

Possible associations of soluble carbohydrates with chemical desiccation and drought resistance in winter wheat

Creator:: Cerono, Julio Cesar
Abstract:: Drought is a major limiting abiotic stress influencing wheat production in many parts of the world. The erratic nature of water deficits makes breeding and selection for drought resistance deficient. In environments with late season drought stress, yield losses are usually associated with kernel abortion or reduction in kernel growth....

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Spring Nitrogen, Plant Growth Regulator, and Defoliation Effects on Seed Production in Two Fine Fescue (Festuca rubra L.) Species

Creator:: Anderson, Nicole P.
Abstract:: One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...

Seed Development in Orchardgrass (Dactylis glomerata L.) in Relation to Plant Growth Regulators and Spring Nitrogen

Creator:: Morad, Mohammed M.
Abstract:: Orchardgrass (Dactylis glomerata L.) is an important seed crop, but unlike other cool-season perennial grass seed crops such as perennial ryegrass (Lolium perenne L.) and tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], seed yields have not increased over time so there is considerable room for improvement. Research suggests that plant growth...
