Laboratory methods for wheat variety identification

Creator:: Ait Amer Meziane, Aomar
Abstract:: There is an increasing need for development of laboratory identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field testing methods based on morphological differences were used satisfactorily. These tests require several months to complete...

Grass seed quality in relation to time of windrowing

Creator:: Dübbern de Souza, Francisco Humberto
Abstract:: This study was undertaken to obtain information on the quality of grass seed when windrowed at the high moisture levels necessary for obtaining maximum yields. A secondary goal was to monitor moisture and temperature fluctuations in the windrow and to relate their effects to development and deterioration of the seed....

The herbicide HOE 23408; soil persistence, spring wheat cultivar tolerance, and interaction with broadleaf herbicides

Creator:: Ivackovich, Branislav D.
Abstract:: HOE 23408 [ 4-(2' , 4'-dichlorophenoxy)-phenoxy-u-propionic methylester.1 is a promising new compound for control of wild oats and other grass weeds in small grains. Several factors influencing its use for this purpose were investigated. Greenhouse bioassay studies were conducted in 1975 to determine relative persistence of HOE 23408 in four...

Cordeauxia edulis : production and forage quality in central Somalia

Creator:: Ali, Hussein Mohamed
Abstract:: Availability of evergreen forage plants during the two dry seasons in arid central Somalia is very important. Cordeauxia edulis is a multistemmed evergreen legume shrub which grows in Central Somalia in plant communities dominated by deciduous shrubs. There are two growth forms of this plant. A form with small leaflets...

Response of Cuscuta campestris and Cuscuta indecora to glyphosate applied after attachment to alfalfa (Medicago sativa)

Creator:: Fessehaie, Rezene
Abstract:: The response to glyphosate [N-(phosphonomethyl) glycine] of two dodder species Cuscuta campestris Yuncker (field dodder) and Cuscuta indecora Chiosy (largeseed dodder) parasitizing alfalfa (Medicago sativa L.) was compared. In the absence of glyphosate, alfalfa was killed or severely injured by parasitism from uncontrolled dodder. Results of field experiments in which...

A taxonomic study of bitterbrush (Purshia tridentata (Pursh) DC.) in Oregon

Creator:: Alderfer, Jean Marie
Abstract:: Extensive morphological and growth habit variations have been reported for bitterbrush (Purshia tridentata), a widespread western shrub frequently used in range revegetation projects. Hybridization of this species occurs with cliffrose (Cowania stansburiana) at the point of their overlapping range in Utah and is believed to be responsible for expression of...
