Allelochemicals fromPilocarpus goudotianus leaves

Journal of Chemical Ecology, 1993
The effect on germination, shoot, and root growth by bergapten, xanthotoxin, imperatorin, xanthyletin, xanthoxyletin, luvangetin, donatin and alloxanthoxyletol fromPilocarpus goudotianus leaves, onLactuca sativa var. nigra seedlings has been evaluated. A structure-activity correlation is discussed based on the bioassay results.

Mineralization of the allelochemical sorgoleone in soil

Chemosphere, 2009
The allelochemical sorgoleone is produced in and released from the root hairs of sorghum (Sorghum bicolor). Studies have confirmed that it is the release of sorgoleone that causes the phytotoxic properties of sorghum, and sorgoleone has a potential to become a new natural herbicide, or the weed suppressive activity of sorghum can be utilized in ...

Lignin and polyphenols as allelochemicals

Industrial Crops and Products, 2008
By the microbiological action, lignin from vegetal wastes is transformed at soil level in organic prebiotic products with physiological activity on plants development. On the other hand, some micromolecular compounds resulted from plant wastes decomposition, along with polyphenols coming from extraction of plant residues could play a role of ...

Potential allelochemicals from Sambucus nigra

Phytochemistry, 2001
Twenty-four aromatic metabolites belonging to cyanogenins, lignans, flavonoids, and phenolic glycosides were obtained from Sambucus nigra. Structures were determined on the basis of their spectroscopic features. Two compounds have been isolated and identified as (2S)-2-O-beta-D-glucopyranosyl-2-hydroxyphenylacetic acid and benzyl 2-O-beta-D ...

Autotoxicity in beans and their allelochemicals

Scientia Horticulturae, 2012
Abstract The autotoxicity of Pisum sativum, Phaseolus vulgaris, and Vicia faba were investigated in hydroponics either with or without activated charcoal (AC) addition. Growth and yield of the three beans were significantly reduced when grown in the culture solution without AC addition. In P.

Searching for Rice Allelochemicals

Agronomy Journal, 2001
A bioactivity‐guided isolation method was developed with the objective of isolating the allelochemicals in rice (Oryza sativa L.). Roots of the allelopathic rice cultivar Taichung Native 1, grown hydroponically, were extracted and fractionated, with the activity of the fractions followed using a 24‐well culture plate microbioassay.

Role of Allelochemicals in Agroecosystems

2020
The biological invasion may discover its root into the marvels of allelopathy, the allelochemicals produced by the plants as a mean of their defense mechanism has turned out to be hindering to the growth of its native plants yet not to their coexisting species due to their adaptive capability (Callaway & Ridenour, 2004).

Allelochemicals in Plants

2008
This chapter presents a brief coverage of a range of common plant allelochemical groups, and includes discussion of their structures, chemistry, distribution, ecology, bioactivity, biosynthesis, allelopathy, and mode of action where known.

Biological Activity of Allelochemicals

2009
All plants produce compounds that are phytotoxic to another plant species at some concentration. In some cases, these compounds function, at least in part, in plant/plant interactions, where a phytotoxin donor plant adversely affects a target plant, resulting in an advantage for the donor plant.
