“…The results showed variations in allelopathic effects due to age and organ of the donor plant as previously reported (Rice, 1984;Inderjit and Asakawa, 2001). Indeed, germination and growth of L. strictum were strongly affected by needle extracts of young pines and roots extracts of older pines.…”

“…Concerning P. halepensis, Maestre et al (2003), observed an inhibitory effect of this species on seedling establishment of various species in pine stands suggesting allelopathic effects of litter or root exudates. Moreover, allelopathic potential may be modified by several factors such as the age of the donor plant (Inderjit and Asakawa, 2001).…”

Potential allelopathic effect of Pinus halepensis in the secondary succession: an experimental approach

Recent economic and social changes in north Mediterranean regions have led to an important rural depopulation. Consequently, meadows developed on abandoned agricultural lands (characterized by high species richness) undergo reforestation. These former fields are mainly colonized by Pinus halepensis Miller, which is known to synthetize a wide range of secondary metabolites, among these, some could influence plant succession through allelopathy. The allelopathic potential of P. halepensis, was tested against two target species (Lactuca sativa L. and Linum strictum L.) with aqueous extracts obtained from different organs (root and needle) taking into account the individual age (±10, ±30 and >60 years old). Root and needle extracts affected differently germination and growth of the two target species, the responses varying with concentration of extracts, age and organs tested. The strongest inhibitory effect was observed on the germination and growth of L. strictum, exposed to needle extracts of young P. halepensis (±10 years old), and root extracts of older P. halepensis (>30 years old). These extracts contained several phenolic acids (e.g. 4-hydroxybenzoic acid and p-coumaric acid), which are known as allelochemicals and their concentrations vary with age and organ tested. Hence, P. halepensis could influence secondary succession through the release of potential allelochemicals in the environment by leaf leachates or root exudates.

“…This allelochemical is also produced in bird vetch (Vicia cracca L.) (Kamo et al, 2006) and black locust (Robinia pseudoacaccia L.) (Kamo et al, 2008). Hairy vetch is used as an annual cover crop in no-till cropping systems as an additional nitrogen source (Inderjit and Asakawa, 2001). An additional benefit of using it is its action as an inhibitor of the growth of some weed species (e.g., whitestar Ipomoea lacunosa L., barnyard grass Echinochlora crus-galli L., prickly sida Sida spinosa L., crabgrass Digitaria sanguinalis L.) (Hoffman et al, 1993;Reddy and Koger, 2004;Hill et al, 2007;Teasdale et al, 2007).…”

We examined the response of plants of various crop and weed species to cyanamide in order to evaluate allelochemical-mediated interactions between the species. We studied germination and seedling growth in the common weeds Galium aparine L. and Amaranthus retroflexus L., and the crops Zea mays L., Triticum aestivum L., Lactuca sativa L., Solanum lycopersicum L. and Sinapis alba L. as acceptor plants. Concentration-dependent phytotoxic effects of cyanamide were noted during seed germination and in the root and shoot growth of the tested plants. The monocotyledonous plants generally were less sensitive to cyanamide treatment. Seed germination and seedling growth of the dicotyledonous plants were strongly inhibited by the allelochemical at both tested concentrations (1.2 mM, 3 mM). We conclude that cyanamide has potential for use as a natural herbicide only in specific field systems of cyanamide-tolerant monocotyledonous crops accompanied by cyanamide-sensitive dicotyledonous weeds.K Ke ey y w wo or rd ds s:

“…In a greenhouse pot study, Inderjit and Asakawa, (2001) [13] determined that interference of hairy vetch with radish (Raphanus sativus L.) was not likely due to allelopathy, while Ercoli et al (2005;2007) [14] [15] attributed weed interference in both field and laboratory studies to phytotoxicity of hairy vetch. A series of greenhouse experiments using leached and unleached hairy vetch shoot tissue grown under field conditions suggested that allelopathy may play a role in weed suppression caused by hairy vetch mulch, but only within the first month after hairy vetch termination/mulch formation [16].…”

The Allelopathic Potential of Hairy Vetch (Vicia villosa Roth.) Mulch

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.
