Biology of Amaranthus retroflexus and Amaranthus viridis
2021Amaranthus species are a key risk to farm production, biodiversity, and agriculture economics of more than 80 countries across the world. A. retroflexus and A. viridis are among the most noxious Amaranthus species. The current information available on the biology these species in Australian agroecosystem is not enough for suitable management ...

Lipids of Amaranthus retroflexus and their Biological Activity
Chemistry of Natural Compounds, 2021The constituent and fatty-acid compositions of neutral lipids (NL), glyco-, and phospholipids and the squalene contents in seeds and the aerial part of Amaranthus retroflexus were studied for the first time. Elaidic acid was observed in all lipid groups. The squalene content was 4.3% of the NL mass in seeds and 3.15% in the aerial part.

Nicosulfuron-resistant Amaranthus retroflexus L. in Northeast China
Crop Protection, 2019Abstract Amaranthus retroflexus L. is a troublesome broadleaf weed in autumn crop fields in China. Farmers complain that A. retroflexus cannot be controlled by nicosulfuron at the recommended field rate in maize fields in Heilongjiang Province. The aim of this study was to determine the molecular basis of nicosulfuron resistance in A.

Predispersal seed predation of redroot pigweed (Amaranthus retroflexus)
Weed Science, 2003Abstract Field experiments were conducted in 1999 and 2000 to determine if (1) seed predation of redroot pigweed plants occurred in agricultural fields, (2) corn-cropping patterns could be manipulated to influence the quantity of weed seed predation, and (3) alterations in corn canopies affected the microenvironment, possibly influencing predator ...

Estimates of physiological determinants forAmaranthus retroflexus
Weed Science, 1999Redroot pigweed is a troublesome weed in the sorghum-growing regions of North America. In 1994 and 1995, field studies were conducted at two locations near Manhattan, KS, to determine the influence of redroot pigweed density and environmental conditions on physiological determinants of redroot pigweed growth: duration of plant growth, light ...
