Effect of plant row spacing and herbicide use on weed aboveground biomass and corn grain yield [PDF]

, 2006
The use of narrow plant spacing in corn (Zea mays) has been suggested as a technological alternative to obtain grain yield increases, due to a better use of resources.

Development, Characterization, and Linkage Mapping of Single Nucleotide Polymorphisms in the Grain Amaranths (Amaranthus sp.)

The Plant Genome, Volume 4, Issue 1, March 2011., 2011
The grain amaranths (Amaranthus sp.) are important pseudo‐cereals native to the New World. During the last decade they have garnered increased international attention for their nutritional quality, tolerance to abiotic stress, and importance as a symbol of indigenous cultures. We describe the development of the first single nucleotide polymorphism (SNP)

Prospección de las combinaciones de herbicidas para prevenir malezas tolerantes y resistentes al glifosato Exploration of herbicide associations to prevent glyphosate tolerant and resistant weeds

Planta Daninha, 2010
El intenso empleo de glifosato contribuyó a la difusión de malezas con tolerancia a este herbicida, incluyendo especies como Ipomoea nil, bejuco en Argentina, o corriola, o corda-de-viola en Brasil. A su vez, el uso intensivo de imadozolinonas en ciertas

Isoform‐resolved genome annotation enables mapping of tissue‐specific betalain regulation in amaranth

New Phytologist, Volume 243, Issue 3, Page 1082-1100, August 2024.
Summary Betalains are coloring pigments produced in some families of the order Caryophyllales, where they replace anthocyanins as coloring pigments. While the betalain pathway itself is well studied, the tissue‐specific regulation of the pathway remains mostly unknown.

Weed seed dormancy as a survival mechanism: brief review [PDF]

, 2008
Um dos principais mecanismos de sobrevivência das plantas daninhas em ambientes constantemente perturbados é a alta produção de sementes. Essas possuem geralmente algum mecanismo de dormência, o qual contribui para a perpetuação de espécies interferentes

First report of target‐site resistance to glyphosate in Amaranthus hybridus L. in the Republic of South Africa

Weed Research, Volume 64, Issue 4, Page 290-301, August 2024.
Abstract Amaranthus hybridus L. is a major weed for summer crops. Although A. hybridus has been a known crop weed in the Republic of South Africa (RSA) for a long time, herbicide resistance has not been a problem. Nevertheless, A. hybridus populations from KwaZulu Natal (KZN) Province have caught the attention of farmers since glyphosate has been ...

Optimization of timing of next-generation emergence in Amaranthus hybridus is determined via modulation of seed dormancy by the maternal environment [PDF]

, 2021
The timing of emergence of weed species has critical ecological and agronomical implications. In several species, emergence patterns largely depend on the level of dormancy of the seedbank, which is modulated by specific environmental factors.
