Fagopyrum esculentum Alters Its Root Exudation after Amaranthus retroflexus Recognition and Suppresses Weed Growth
Weed control by crops through growth suppressive root exudates is a promising alternative to herbicides. Buckwheat (Fagopyrum esculentum) is known for its weed suppression and redroot pigweed (Amaranthus retroflexus) control is probably partly due to allelopathic root exudates. This work studies whether other weeds are also suppressed by buckwheat and if the presence of weeds is necessary to in...
متن کاملRole of Ethylene Metabolism in Amaranthus retroflexus.
(14)C-Ethylene was metabolized by etiolated pigweed seedlings (Amaranthus retroflexus L.) in the manner similar to that observed in other plants. The hormone was oxidized to (14)CO(2) and incorporated into (14)C-tissue components. Selected cyclic olefins with differing abilities to block ethylene action were used to determine if ethylene metabolism in pigweed is necessary for ethylene action. 2...
متن کاملAdverse Reactions Triggered by Amaranth Allergens-What We Know So Far from a Molecular Perspective
The genus Amaranthus contains 44 species and belongs to the family of Amaranthaceae classified within the order of Caryophyllales. Within this order a number of allergenic species including Amaranthus retroflexus (Redroot pigweed), Beta vulgaris (sugar beet), Chenopodium album (Lambsquaters), Kochia scoparia (Burning bush), and Salsola kali (Russian thistle) have been acknowledged by the WHO/IU...
متن کاملAllelopathic effects of Chenopodium album, Amaranthus retroflexus and Cynodon dactylon on germination and growth of safflower
According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...
متن کاملComparative Genotoxicity of Herbicide Ingredients Glyphosate and Atrazine on Root Meristem of Buckwheat (Fagopyrum esculentum Moench)
Herbicides have been extensively used in agriculture but people have not concerned about its adverse effects on plants and animals. The aim of the present study is to analyze the detrimental effects of two herbicides in Fagopyrum esculentum Moench (Variety: VL-7). The root tips were treated with four concentrations viz. 50, 100, 150 and 200 ppm of glyphosate and atrazine at room temperature for...
