Quackgrass (Elytrigia repens) Interference in Canola (Brassica campestris)
Weed Science, 1991The effects of quackgrass shoot populations shortly after emergence, and dry weight at harvest on yield of canola were determined in four field experiments conducted near Vegreville, Alberta in 1986 and 1988. A hyperbolic model described the data well in most cases and indicated little intraspecific quackgrass interference among quackgrass shoots until

Basis for the Differential Response of Quackgrass (Elytrigia repens) Biotypes to Primisulfuron
Weed Science, 1994Factors accounting for the differential response of five quackgrass biotypes to primisulfuron were compared. Previous field and greenhouse experiments had identified a biotype from Montpelier, OH, as being less susceptible to primisulfuron than biotypes from Amherst, MA; Mahnomen, MN; Fargo, ND; and State College, PA.

Weed Technology, 1990
An established alfalfa stand infested with quackgrass received fluazifop-P, haloxyfop, or quizalofop at single applications of 0.28 ae kg ha-1and sequential applications of 0.14 plus 0.14 ae kg ha-1with the second treatment being made 16 d after the first. All herbicide treatments increased diffusive resistance and decreased transpiration of quackgrass

Effect of Tillage and Glyphosate on Control of Quackgrass (Elytrigia repens)
Weed Technology, 1994Field studies were conducted during two soybean-corn rotations to evaluate the effect of tillage systems on quackgrass growth and control with and without glyphosate. In the final year of the study, tillage alone (compared to no-till) resulted in 88%, 78%, 64%, and 31% control of quackgrass with fall moldboard plow, spring moldboard plow, fall soil ...

Temporal Changes of Elytrigia repens Density in Intensive Cereal-Based Cropping Systems
2020The common effects of cultivation practices, weed management measures and crop rotation on Elytrigia repens population dynamics under condition of large scale fields were studied in South-Western Slovakia during 2007-2014. The evaluated fields reflect the changes of cultivation practices associated with the growing crops in intensive crop rotation ...

Rhizome Bud Viability of Quackgrass (Elytrigia repens) Treated with Glyphosate and Quizalofop
Weed Technology, 1990The effect of the isopropylamine salt of glyphosate and the ethyl ester of quizalofop on the rhizome bud viability of five quackgrass biotypes was tested. Two bioassays used were: direct measure of the growth of the bud on an agar medium and determination of the respiratory activity with tetrazolium chloride.

STUDY OF CHEMICAL COMPOSITION AND STANDARDISATION OF ELYTRIGIA REPENS (L.) NEVSKI RHIZOMES
ACHIEVEMENTS AND PROSPECTS OF CREATING NEW HERBAL MEDICINESWheatgrass (Elytrigia repens (L.) Nevski) is a perennial plant of the Northern Hemisphere. It has a wide range of pharmacological activity. At the same time, the data of literature sources devoted to the study of rhizome composition are very different, and sometimes contradict each other.

Hybridization is an important phenomenon in plant evolution because it is one of the sources of new genetic variability. Hybridization is the merging of genomes of formerly isolated evolutionary lineages. In many taxonomic groups, the detection of plants of hybrid origin is challenging.
