Karyotype analysis of Common Cocklebur (Xanthium strumarium L.)

Natural Science and Discovery, 2017
Objective: The purpose of this study is to determine the mitotic chromosome number, morphometric parameters, and karyotypes of Xanthium strumarium and make contributions to other multidisciplinary studies on the genus. Material and Methods: The seeds were germinated on moist filter paper in Petri dishes at 25°C.

Bromoxynil for Control of Common Cocklebur and Wild Common Sunflower in Soybeans

Weed Science, 1973
In preliminary greenhouse evaluations and then in field studies, common cocklebur (Xanthium pensylvanicum Wallr.) and wild common sunflower (Helianthus annuus L.) were controlled by early postemergence applications of 3,5-dibromo-4-hydroxybenzonitrile (bromoxynil).

Biochemical Features of Common Cocklebur (Xanthium strumarium L.)

Pharmaceutical Chemistry Journal, 2015
Biochemical features of wild common cocklebur (Xanthium strumarium L.) were studied in order to assess its possible cultivation. Analyses showed high contents of fatty oil in seeds (up to 40%) and fruit (up to 12%) that consisted of unsaturated (palmitic, stearic) and more valuable polyunsaturated (linoleic, linolenic) acids.

Photosynthetic activity of MSMA-resistant and -susceptible common cocklebur

Pesticide Biochemistry and Physiology, 2003
Abstract MSMA-resistant (R) and -susceptible (S) biotypes of common cocklebur (Xanthium strumarium L.) were used to study PSI and PSII activities, and chlorophyll and carotenoid content of MSMA-treated and -untreated R and S biotypes. MSMA at 1, 10, and 100 mg/L did not inhibit either PSI or PSII activities.

Translocation of Bentazon in Soybeans and Common Cocklebur

Weed Science, 1976
Translocation of14C-labeled and toxicity of nonradiolabeled bentazon [3-isopropyl-1H-2,1,3-benzothiadiazin-(4)3H-one 2,2-dioxide] was determined for common cocklebur (Xanthium pensylvanicumWallr.) and soybeans [Glycine max(L.) Merr.]. Significantly greater14C-movement and herbicide toxicity occurred in common cocklebur growing in wet soil at field ...

Genetic relationships of common cocklebur accessions from the United States

Weed Science, 2001
Abstract DNA fragment analysis, based on amplification of intersimple sequence repeats by the polymerase chain reaction (ISSR-PCR), was used to assess genetic relationships of 217 U.S. accessions of common cocklebur. Twenty-four polymorphic markers were generated from six primers.

Control of common cocklebur (Xanthium strumarium L.) in corn

Canadian Journal of Plant Science, 2010
Nine field trials (five with PRE and four with POST herbicides) were conducted in 2006 to 2009 on various Ontario farms with heavy common cocklebur infestations to determine the effectiveness of PRE and POST herbicides for the control of common cocklebur in corn.

Common Cocklebur (Xanthium strumarium) Resistance to Selected ALS-Inhibiting Herbicides

Weed Technology, 1997
Five biotypes of common cocklebur that were not controlled with acetolactate synthase (ALS)-inhibiting herbicides were tested in greenhouse and laboratory studies to determine the magnitude of resistance and cross-resistance to four ALS-inhibiting herbicides. In vivo inhibition of ALS was also evaluated.

Photosynthetic Performance of MSMA-Resistant and -Susceptible Mississippi Biotypes of Common Cocklebur

Pesticide Biochemistry and Physiology, 1995
Abstract Common cocklebur biotypes resistant to monosodium methanearsonate (MSMA) have been reported in South Carolina, Mississippi, and other locations. The resistance at the whole plant level in Mississippi biotypes was found to be low under growth chamber and greenhouse conditions.

Dry matter yield differences of five common cocklebur (Xanthium strumarium) biotypes grown at a common site

Weed Science, 2003
Five common cocklebur biotypes from southern Minnesota, central Iowa, southern Iowa, and Ohio were grown at the Iowa State University Curtiss Research Farm in 1995 and 1996 to examine intraspecific variations. Maximum plant heights were measured, and anthesis dates and day of bur set were recorded.
