“…Several allelochemicals are found in sorghum, distributed in leaves, stems, roots, flowers and fruit (Santos, 1996). These include the chlorogenic acids pcoumaric and p-hydroxybenzaldehyde, found in S. halepense Pers., (Abdoul-Wahab and Rice, 1967); dhurrin, found in S. halepense (Nicolieur et al, 1983), S. sudanense and S. bicolor (Gorz et al, 1977); sorgoleone, found in S. bicolor and S. sudanense (Netzly et al, 1988); as well as strigol and sorgolactane, both present in S. bicolor (Hauck et al, 1992). According to Rice (1984), the effects of sorghum allelochemicals are concentration-dependent and selective.…”

-Known since ancient times, the phenomenon of allelopathy has recently received greater attention from researchers and farmers worldwide. Crop failures and low yields caused by the reseeding, overseeding, crop rotation and replanting of fruit trees in orchards are believed to be caused by allelopathic activity. Moreover, the expensive and environmentally impacting herbicides for weed control have motivated studies directed at developing cheaper, environmentally-friendly alternatives. Despite the difficulties in separating chemical interference from other mechanisms, more modern approaches have produced consistent and conclusive data on this topic. The release and dynamics of allelochemicals in the soil are discussed herein. Examples of allelopathic crops, the allelochemicals produced and their uses in cropping systems are also presented along with current research trends regarding allelopathy. allelopathy / chemical interference / agriculture / potential use

The phenomenon of allelopathy encompasses all types of chemical interactions among plants and microorganisms. Several hundred different organic compounds (allelochemicals) released from plants and microbes are known to affect the growth or aspects of function of the receiving species. Many new allelochemicals have been identified in recent years and it has become clear that the actions of allelochemicals are important features characterizing the interrelationships among organisms. These compounds influence patterns in vegetational communities, plant succession, seed preservation, germination of fungal spores, the nitrogen cycle, mutualistic associations, crop productivity, and plant defense. Allelopathy is tightly coupled with competition for resources and stress from disease, temperature extremes, moisture deficit, and herbicides. Such stresses often increase allelochemical production and accentuate their action. Allelopathic inhibition typically results from a combination of allelochemicals which interfere with several physiological processes in the receiving plant or microorganism. Other than the autecological study of specific species, there are persistent challenges in allelopathy to determine the mechanism of action of compounds, isolate new compounds, evaluate environmental interactions, and understand activity in the soil. New frontiers will focus on ways to capitalize on allelopathy to enhance crop production and develop a more sustainable agriculture, including weed and pest control through crop rotations, residue management, and a variety of approaches in biocontrol. Other goals are to adapt allelochemicals as herbicides, pesticides, and growth stimulants, modify crop genomes to manipulate allelochemical production, and better elucidate chemical communications that generate associations between microorganisms and higher plants. 0097 ALLELOPATHY: ORGANISMS, PROCESSES, AND APPLICATIONSThe writings of some natural philosophers that date back more than two millenniums show that they recognized chemical influences in nature (1). However, it is the evidence accumulated over the last several decades which has established that external roles for biochemicals, meaning roles that do not directly affect the basic physiology of the producing organism, are pervasive themes characterizing the interrelationships among organisms. This realization does not diminish the respective importance that competition for resources has on the relative success of an organism or a species. Instead, chemical ecology extends our dimensions of understanding and provides new insights into the intricacies of interchanges that occur in an ecosystem, community, or population.Allelopathy, a subset within the broader scope of chemical ecology, is concerned with effects that chemicals of plant or microbial origin have on growth, development, and distribution of other plants and microorganisms in natural communities or agricultural systems. The aims of this overview chapter are to provide a synthesis of the scope of allelopathy, suggest gen...

“…Aqueous extracts of foliage and litter of a number of plant species have been shown to be allelopathic. Rice and co-workers have shown that in addition to phytotoxic root exudates, inhibitory leachates of leaves and litter of pioneer and seral species can have a significant effect on rates of succession in abandoned fields in the American midwest (Abdul-Wahab and Rice, 1967;Neill and Rice, 1971;Parks and Rice, 1969;Rasmussen and Rice, 1971;Rice, 1968Rice, , 1971Rice, , 1972Wilson and Rice, 1968).

The allelopathic potential of Rhododendron macrophyllum in a western Cascades clearcut

Rhododendron macrophyllum is a dominant species in.the shrub stage of secondary succession on burned and logged sites in the Tsuga heterophylla zone of the western Cascades of Oregon. A study was undertaken to determine if R. macrophyllum has the potential to inhibit the germination and growth of surrounding ~egetation through watersolub le toxins which . . are produced in its leaves and leached out of its litter by rainfall.Aqueous extracts of R. macrophyllum leaf litter significantly reduced germination and radicle growth in Btomus tectorum, ·Epilobitim ansustifolium, Picea sitChensis, ·pseudOtStiga·menzieSii, and·Tsu8a heterophylla. Osmotic pressure of the leaf extract solution was determined not to be a significant causative factor in the inhibition observed.Field studies showed four plant species to increase in frequency of presence with increasing distan~e from _1!. macrophyllum drip lines.Two species, both ericaceous, decreased in frequency of presence.Five species increased in density with increasing distance from R. macrophyllum drip lines, while only one species, which was ericaceous, decreased, It is postulated that these patte~s result fr~ the allelopathic influence of _1!. macrophyllum. Members of the Ericaceae are thought to either have a common response to environmental conditions or to be able to tolerate the toxins produced by members of thei~ family.
