“…The development of analytical techniques allowing better specification of direct effects of allelopathins, have moved the exploration (or the research on) of this phenomenon from fields into laboratories. The term "allelopathy" refers rather to interactions occurring in the natural environment [5]. For studies with plant extracts, allelopathins isolated from plant tissue, collected from exudates or even synthetic compounds identical to natural ones, it was established the term ''phytotoxicity'' to distinguish allelopathy (as a phenomenon occurring in natural environment) from studies conducted in laboratory.…”

“…Cyanamide solution, in a petri-dish assay, decreased the quantity of mitotic cells, suppressed the propagation of meristematic cells, and altered the cytoskeleton arrangement in onion (Allium cepa L.) [34]. In a subsequent study on tomato, cyanamide inhibited root growth, likely due to altered cell division, an imbalance of the hormones ethylene and auxin, and differences in expansin gene expression [35]. To date, no research has been conducted on cyanamide mode of action using the species evaluated in this study.…”

Hairy vetch (Vicia villosa Roth.) has been recognized as a good candidate for weed suppressive mulch in organic no-till cropping systems. In our study, the allelopathic potential of hairy vetch, fall rye (Secale cereale L.) and winter wheat (Triticum aestivum L.) (extracted species) were evaluated at both vegetative and reproductive developmental stages (extract stage) based on the germination and radicle elongation of five response species using aqueous extracts in soil microcosms. Our study found hairy vetch shoot extract to have little allelopathic potential compared to fall rye or winter wheat, both species for which the allelopathic potential is well documented. Interestingly, hairy vetch was the only extracted species to increase in allelopathic suppression of radicle elongation at the reproductive stage when plant biomass is near maximum. This result was conceivably due to the increased concentration of the putative allelochemical cyanamide in reproductive tissue. Chemical inhibition of radicle elongation in this extract, however, was only observed in the domesticated response species wheat (Triticum aestivum L.) and canola (Brassica napus L.). The allelopathic effect on germination varied and depended on extracted species, extract stage, and response species; whereas the effect on radicle elongation was similar among extracted species, yet unique within response species. This research demonstrated that allelopathy studies should include multiple allelopathic and response species to accurately quantify the magnitude of chemical effects among allelopathic species and to rule out potential phytotoxic chemical defense/detoxification mechanisms that exist in some response species.

“…13 Bleach blue color as well as its lower incidence indicating decreased O 2 · -content after 3 days of CA treatment may be an effect of inhibition of cell proliferation and root tip shrinkage. 5 On the other hand, decreased H 2 O 2 may be related to disorder in differentiation of cells that have already moved from the meristematic zone.…”

Moreover, disorder in mitosis was correlated with altered expression of expansin genes (LeEXPA9 and LeEXPA18) involved in reconstitution of cell wall after Mode of action of allelochemicals in target plants is currently widely studied.…”

Allelopathic interactions have mainly negative character on targeting plants. Inhibition and/or delay of seed germination or seedling growth of acceptor plants is an effect of mostly diversified mode of action of allelochemicals.1 It means that inhibition of activity of one enzyme or slowdown of the process triggers cascade of events leading to initialization of signal transduction and/or switching on cell's defense mechanisms. However, nature of allelopathic interactions is time and dose dependent and differs in various plant species and depends on other environmental factors. Most studies on allelopathy are conducted under laboratory conditions due to elimination of non-direct effects coming from environment. In this way, the phenomenon of interaction of allelochemical on acceptor plants is called phytotoxicity.Cyanamide (CA) is one of the newly discovered allelochemical, found in hairy vetch (Vicia villosa subs. cracca Roth.) and crucial for its allelopathic potential.2 Research on phytotoxic action of CA confirmed its abilities in inhibition of seed germination and seedling growth of various plant species. 3Mode of action of CA on root growth was partially examined in onion bulbs. 4 Our former studies, conducted on tomato seedlings, indicated disturbances in root tip cells division leading to reduction of length of root tip zone, as the main reason of CA-induced root growth inhibition. 5 This, in consequence, reorganized every other root zones. Moreover, disorder in mitosis was correlated with altered expression of expansin genes (LeEXPA9 and LeEXPA18) involved in reconstitution of cell wall after Mode of action of allelochemicals in target plants is currently widely studied. Cyanamide is one of the newly discovered allelochemical, biosynthesized in hairy vetch. recently, it has been recognized that cyanamide is plant growth inhibitor, which affects mitosis in root tip cells and causes, e.g., disorder in phytohormonal balance. We also demonstrated that Ca may act as oxidative stress agent but it strictly depends on plant species, exposure time and doses. roots of tomato seedling treated with water solution of 1.2 mM cyanamide did not exhibit elevated reactive oxygen species concentration during the whole culture period.
