Amaranth is a multi-purpose crop, known for its wound-healing properties. Amaranth leaves and seeds contain polyphenols and flavonoids that improve wound healing. Ethanol extracts of amaranth seeds of “Lera” and “Ultra” varieties and ethanol extract of leafs Amaranthus retroflexus were obtained. Determination of the content of polyphenolic compounds in the extracts was conducted by the spectrophotometric method with the Folin-Checolteau reagent.

Amaranthus retroflexus or redroot pigweed is a second generation lignocellulosic fuel. Each biomass sample (leaves, inflorescences and stems) was pyrolyzed in a lab-scale furnace, in a nitrogen atmosphere under non-isothermal conditions at heating rates of 10 °C/min until the furnace temperature reached 550 °C. The pyrolysis characteristics of the three major components were also studied through thermogravimetric analysis.

Resumen
Amaranthus retroflexus L. is widely regarded as one of the world’s most invasive weeds, often linked to significant agricultural losses due to its resilience and herbicide resistance. However, unlike other amaranth species already recognized for their health benefits, A. retroflexus remains largely overlooked as a potential nutritional and pharmacological resource. This study investigates whether this abundantly growing plant could be repurposed as sustainable food. We focused on three main questions: Can weed be transformed into a food source?

Resumen
Amaranthus retroflexus L. is among the important weeds in sugar beet. The aim of this study was to determine the germination capacities of the seeds obtained from A. retroflexus plants, who survived after the application of chloridazon (C), metamitron (M) and ethofumesate + phenmedipham + desmedipham + lenacil (EPDL) herbicides and some combinations. Parameters of total germination rate (%), normal/abnormal germination rate (%), mean germination time (day) and seed weight (g) were defined. As a result, germination characteristics of A. retroflexus plants exposed to chloridazon + ethofumesate +

Aim of study: To determine and quantify the effect of seed burial depths on the seedling emergence pattern of Amaranthus retroflexus in field conditions.
 Area of study: West of Iran (Ilam).
 Material and methods: The seedling emergence of an A. retroflexus was studied in an outdoor pot experiment, burying the seeds at 0, 2, 4, 6 and 8 cm in the soil in Ilam (Iran) in two consecutive years, 2010 and 2011. Different models were tested to predict the cumulative seedling emergence, and the log logistic model was found to be the best for this A. retroflexus population. Newly estimated Tb

Resumen
Amaranthus retroflexus L. is one of the malignant weeds which can cause a reduction in the soybean yield. We found a population of A. retroflexus (R-Q) resistant to fomesafen through the initial screening of whole-plant dose response bioassay in the research. The resistance index of the population (R-Q) was 183 times of the sensitive population (S-N). The resistant and sensitive populations were used as experimental materials in the paper. Strand-specific RNA-Seq analyses of R‒Q and S‒N populations obtained from herbicide-treated and mock-treated leaf samples after treatment were conducted to

Abstract Biotypes of Amaranthus retroflexus L ., A. hybridus L., A. bouchonii Thell. and Chenopodium album L. insensitive to atrazine were collected from maize monoculture where atrazine had been applied extensively. Atrazine-resistant biotypes of A. retroflexus and A. hybridus showed phenmedipham and lenacil co-resistance and atrazine-resistant biotype of C. album showed fenuron co-resistance. An atrazin-resistant biotype of A. bouchonii with co-resistance to diuron was not resistant to fenuron, lenacil and phenmedipham.

The paper addressed the study of some biological features of two weed species of Amaranthus L. – a widespread species A. retroflexus L. confined to Siberia and a rare species Amaranthus blitum L. Plants of different vital status were found in populations of two species invading potato plantations. The paper reports the morphometric parameters of normally developed and small plants of both species. The features of seed germination and the degree of seedling development were revealed.

Resumen
Amaranthus retroflexus L. is a troublesome dicot weed in crop fields and has developed high resistance to nicosulfuron in China. The objective of this study was to determine the effects of specific resistance mutations (A205V, D376E, W574L, S653T, and S653N) of the acetohydroxy acid synthase enzyme (AHAS) on the resistance of A. retroflexus to nicosulfuron. The resistance mutations in A. retroflexus not only conferred 17.17- to 31.70-fold resistance to nicosulfuron but also greatly decreased AHAS sensitivity and increased AHAS binding affinity to substrate pyruvate, which mechanisms were prima

Resumen
When in competition with cotton, Amaranthus retroflexus can cause high yield losses. Due to the limited availability of selective herbicides registered for post emergence control of this weed, the same herbicides have been used repeated times over the last few years, which may have selected resistant biotypes. Biotypes of A. retroflexus collected from the main areas of cotton cultivation in Brazil were submitted to dose-response trials, by applying the herbicides trifloxysulfuron-sodium and pyrithiobac-sodium in doses equivalent to 0, ¼, ½, 1, 2 and 4 times the recommended rates.

A morphometric study of Amaranthus cruentus, A. retroflexus and their hybrid, A. × turicensis based on 75 plant samples (750 inflorescences), collected throughout the Olomouc-Holice area (Czech   Republic), is presented. Using multivariete methods (including cluster analysis and canonical discriminant analysis), the existence of three groupings of plants was proven. The hybrid exhibited intermediate values of the width and length of female tepals, length of awl-shaped bracts, and seed size when compared with parental species.
