During the last half of the twentieth century, agricultural production came to depend on a wide array of chemical inputs that were designed to control a complex of weed, insect, and disease organisms. The use of these chemicals is most often evaluated in terms of their efficacy in controlling pests, lowering yield losses, and increasing the output and ...

Allelopathy in Agroecosystems in Spain
Journal of Crop Production, 2001Summary This paper reviews the effects of allelopathic interactions in agroecosystems in Spain on plant physiological activity and their ecological advantages. The phenological stage of growth of donor plants and the effective allelochemicals in the soil solution while studying the role of phenolic compounds were highlighting.

The Botanical Review, 1979
The latest previous comprehensive review of allelopathy (Rice, 1974) covered research done primarily prior to 1973. There have been numerous reviews published in recent years on specific phases of allelopathy (see III), but most of them covered research results published primarily through 1972 also.

On laboratory bioassays in allelopathy
The Botanical Review, 1995Allelopathy involves the complex chain of chemical communications among plants, including microbes. Laboratory bioassays constitute a significant part of allelopathic research, and various bioassays have been proposed to demonstrate allelopathy under controlled lab conditions.

Allelopathy in citrus orchards
Scientia Horticulturae, 1983Abstract The involvement of allelopathy in citrus orchards is indicated by the discovery of a phenolic phytotoxin in soils and partly decomposed citrus root residues. The phytotoxin, which was tentatively identified as homovanillic acid, is produced by the anaerobic decomposition of citrus roots in the deeper soil horizons.

A perspective of Allelopathy in Agriculture
Allelopathy is the process by which one plant produces chemicals that impede the growth and development of another plant. Allelochemicals have been suggested as a promising drug development method for environmentally friendly biological weedicides and frequently promote or inhibit plant growth.Supriya R. Nikam, Dr. D.

Ecophysiological Approach in Allelopathy
Critical Reviews in Plant Sciences, 1999Allelopathy is a process that can be present in many ecosystems, according to the literature. Nevertheless, the authors think that, due to the evolutionary constraints, especially from a co-evoluti...

Allelopathy: Introduction and Concepts
2017Plants communicate and influence the growth of other plants (or even microorganisms) through excretion of certain chemical compounds (allelochemicals). The process is called allelopathy. A number of allelochemicals have been reported from different plant species.

Allelopathy in Compositae Plants
2011Allelopathy plays an major role in agricultural management such as weed control, crop protection, and crop re-establishment. Compositae plants have potent allelopathic activity, and the activity is confirmed through (a) bioassays with aqueous or various solvent extracts and residues, (b) fractionation, identification, and quantification of causative ...

Allelopathy and Crop Nutrition
2012Allelopathy, the natural phenomenon of production and release of secondary metabolites and interaction(s) among organisms, is a subject of diverse significance and applications in plant sciences. Other than their role in plant defense against biotic and abiotic stresses, plant secondary metabolites or allelochemicals play a significant role in plant ...
