Allelopathy is a biotic interaction between plants where one plant inhibits the germination and growth of other by releasing certain allelochemicals. In this research we evaluated allelopathic effect aqueous leaf extract Lantana camara on four crop plants. The experiment was conducted in sterilized petri dishes Botany lab Saptagandaki Multiple Campus, Bharatpur, Chitwan, Nepal. different concen...

The ability of cyanobacteria to produce complex secondary metabolites with potent biological activities has gathered considerable attention due to their potential therapeutic and agrochemical applications. However, the precise physiological or ecological roles played by a majority of these metabolites have remained elusive. Several studies have shown that cyanobacteria are able to interfere wit...

Abstract Allelopathy, a complex phenomenon has unveiled both stimulatory and inhibitory effects in plant processes that are mediated by the release of certain chemical compounds commonly known as allelochemicals. Allelochemicals, form bioactive secondary metabolites produced diverse group plants microbes response to biotic abiotic stress. It ranges from simple hydrocarbon polycyclic aromatic li...

Coral reefs are in dramatic global decline due to a host of local- and global-scale anthropogenic disturbances that suppress corals and enhance seaweeds. This decline is exacerbated, and recovery made less likely, due to over-fishing of herbivores that normally limit seaweed effects on corals. Seaweeds were known to suppress coral reproduction and recruitment, but in a recent study, we demonstr...

Glucosinolates are allelochemicals present in all Brassica plants. Upon hydrolysis by endogenous enzymes they produce a series of biologically active compounds, such as isothiocyanates and their derivatives among others. These compounds have marked fungicidal, nematocidal and herbicidal effects and therefore their use as biodegradable natural products for crop protection has attracted much atte...

Inhibition of phytoplankton by allelochemicals released by submerged macrophytes is supposed to be one of the mechanisms that contribute to the stabilisation of clear-water states in shallow lakes. The relevance of this process at ecosystem level, however, is debated because in situ evidence is difficult to achieve. Our literature review indicates that allelopathically active species such as My...

BACKGROUND Exploring the residence time of allelochemicals released by plants into different soils, episodic exposure of plants to allelochemicals, and the effects of allelochemicals in the field has the potential to improve our understanding of interactions among plants. METHODOLOGY/PRINCIPAL FINDINGS We conducted experiments in India and the USA to understand the dynamics of soil concentrat...

The sensitivities of Selenastrum capricornutum and the toxic strain Microcystis aeruginosa to exudates from Potamogeton maackianus and P. malaianus were compared using exudation experiment, and the potential allelochemicals released by these two pondweeds into surrounding water were also analyzed. The growth of S. capricornutum and M. aeruginosa was inhibited by the exudates from the two macrop...
