potential of Gleichenella pectinata (Willd.
However, on page 243 Small reminds us that, "Cannabis sativa has minor allelopathic
properties (Inam et al.
relationships may occur in a positive or negative manner through the production of chemical compounds known as allelochemicals.
Its aggressive growth, in addition to allelopathic
properties, results in displacement of native vegetation and changes in plant community structure (Morton 1978; Morgan & Overholt 2005).
In addition, other factors such as an initial shading in the crops, possible translocation of herbicide from target plants (cover crops) to non-target plants (cash crops), increasing demand for nitrogen by decomposing microorganisms, allelopathic
effects and other aspects still must be studied, understood and avoided (Weston, 1990; Miyazawa et al.
ex Steudel, with allelopathic
effects produced by a cyanobacterial bloom where the cyanobacteria Microcystis predominated (Yamasaki, 1993).
Because the 25% level had a smaller amount of extract this was not enough to facilitate germination but at other levels, and with increased extract allelopathic
comparisons with the controls showed significant difference.
Additionally, some invasive exotic plant species release allelopathic
toxins that can inhibit or kill native plants (Ridenour and Callaway, 2001; Prati and Bossdorf, 2004; Thorpe et al.
Parthenium plant contains chemicals, like parthenin, hysterin, hymenin, and ambrosin, and due to the presence of these chemicals, the weed exerts strong allelopathic
effects on different crops.
ABSTRACT: A field study was conducted at Agronomic Research Area, University of Agriculture, Faisalabad, during summer season in the year 2007 to explore the possibility of reducing herbicide doses in combination with water leachates of allelopathic
crops in rice.
effects may also interact with competition for resources between some Amaranthus species and the crop in which they are growing (Connick et al.
The sand roads at Archbold Biological Station provide habitats for plant and animal species that ordinarily colonize gaps produced by fire or the allelopathic
litter of Ceratiola ericoides Michx.
