Talk:Allelopathy

message: Allelopathy is not limited to plants. For instance, there's literature referring to chemical interference between zooplankton as allelopathy.

message: Anybody know why all the nouns in this article are preceded by either font Class = "SpellE" or font class="GramE".  These seem to be HMTL tags, but I do not think they relate to Wikipedia, do they? - Marshman 02:54, 11 August 2005 (UTC)
replies: text: Those tags aren't used in Wikipedia, so you can safely chop them out.--nixie 03:48, 11 August 2005 (UTC)

message: The introductory sentence: "The term allelopathy denotes the production of specific biomolecules by one plant that can induce suffering in, or give benefit to, another plant." Is it really in the definitioon of allelopathy that mutualism could be included? - Marshman 20:44, 9 November 2005 (UTC)
thread_title:  Benefit? 

message: allelopathy means disease and symbiosis is another article. Perhaps I should install a thesauric link. Symbiosis is more like the relation between fungus (when undergrond) and plant or saprophyte (mistechnical word, but I don't remember the other one) and plant.
In the section about demonstrating the effect, I question the fifth criterion.
"afflicted plants have means of uptake of toxin"
If the toxin blocks needed chemistry from the soil, then I think you still hav one plant promoting disease in another. On the symbiotic relationships, you might note that wormwood suppresses worms in the soil, which might benefit radishes. I could snip Criterion five with a comment, and the whole exception should be visible. Ah:
The toxin must affect the metabolism of a neighbouring plant.

thread_title:  Criteria in Demonstration of Effect 

message: Ref 1 cites a book taken directly from the French Wikipedia. In both version there is an ISBN No given. In the French version the citation is accepted as it is. Here a remark is put after it and we are directed to discuss the matter here. Unfortunately I don't know what is amiss and what we are discussing. How can the citation of an English work be right on the French Wiki, wrong here? Have I copied something wrongly? Can anyone comment?LouisBB (talk) 22:09, 8 August 2009 (UTC)

message: In an article at Encyclopedia of Life Sciences on chemical ecology, an allelochemical is definied as a semiochemical that mediates interactions between species, which is quite different to the use here. It seems the terminology is somewhat confused between different fields. Richard001 (talk) 02:36, 25 April 2010 (UTC)
replies: text: Yes, there is quite a bit of confusion about the term. I was in the middle of editing the article when I came across this statement: "Whittaker and Fenny...defined allelochemicals as all chemical interactions among organisms." First off, it's Feeny, not Fenny. Secondly, this definition is way too broad. I have a feeling that the study was either misinterpreted or badly paraphrased.

thread_title:  Definition of allelochemical 

message: We have this article, Phytoncide (specific variant?), and Heterotelergone, which is apparently a synonym article without any extra content. Would it be appropriate to redirect from there to here, and do something about the diverse categories of these three supposedly related articles (currently botany, chemical ecology, biomolecules, pheremones, toxins, biochemistry stubs, phytochemicals, biologically based therapies, alternative medicine stubs)?--Martin Berka (talk) 18:59, 5 December 2011 (UTC)
thread_title: Clarification/Consolidation?

message: Deleted the following sentence at the end of the examples section:
"Corn gluten meal (CGM) is a natural preemergence weed control used in turfgrass, which reduces germination of many broadleaf and grass weeds."
Use of CGM is not an example of allelopathy. It is not an example of plants suppressing growth, by chemical means, of nearby plants. It is an example of use of a plant product as a low efficacy, pre-emergence herbicide. The only possible reason justifying the inclusion of this example would be if it were intended to imply the notion that maize may produce allelopathic effects —a notion that seems implausible to me. In any event, even if this inference did not fail the plausibility test, something that may hint at a possibility of a thing occurring should not be included as an example of said thing actually occurring.
Indeed, Dr. Linda Chalker-Scott at her Horticultural Myths entry on The Myth of Weed-Killing Gluten advances the position that desiccation is a necessary component of the herbicidal action on germinating seeds by CGM. If this is correct, it is not even plausible that the same mechanism of action suppressing seed germination when CGM is used could function in the context of whole, living maize plants producing some alleged allelopathic effect. This, of course, does not prove that maize produces no allelopathic effects (though I suspect any farmer would argue that it doesn't) but it does make it evident that use of CGM as a pre-emergence herbicide does not point to the existence of allelopathic effects of maize plants.

message: Parallel-to of course conservation in terms of rejuvenation or attempts at ecology restoration where core species are floral components that have allelopathic productive capacities and in order to attempt it allelopathic species must be chosen for a particular ecology or habitat such as for Koalas,
there should? or could? be a section in the page ;
on the potential of underestimating the risks from allelopathic species in terms of the DIFFERENT rates / durations / toxic-potency of the compounds running leeching, or draining downstream or downhill(1), and (2) distribution via wind;
—
Dynamics could include comparative differences due to natural migration or via animal species to places they would not or do not normally inhabit, in terms of their normal interactions with or via water, WHEN THEN transported downhill ;
---
Physics of it ;
faster/slower movement,
collection points, concentration levels,
wind scattering before toxic-breakdown, etc.
---
Context of it ;
Surface soil types/dynamics/interactions (especially if an introduced species)
Terrain inclination,
Rainfall differences,
Differences in norms of wind,
Climate change complications,
Plantations (sometimes) causing unnatural concentration levels,
Etc
.
