Allelopathy (allelon – “of each other” and pathos – “to suffer”) is the chemical inhibition of one species by another. This phenomena is frequently found in plants where one species of plant releases a chemical into the environment that inhibits the growth of another species of plant. An example is the Creosote bush, which releases terpenes into the surrounding soil to inhibit the growth of other plants.

19. Describe what might be observed in a habitat that would indicate a plant species is allelopathic?

20. Considering what you know about population distribution, what type of distribution is likely to arise as a result of allelopathy? Justify your answer using complete sentences.

21. What would be some advantages of allelopathy to a plant?

22. What would be some disadvantages to the ecosystem where allelopathic plants grow?

23. Is it likely that a species that exhibits allelopathy would evolve over time? Explain your answer using what you know about the mechanisms of evolution.

24. The sorghum plant releases the allelotoxin sorgolene that disrupts mitochondrial functions and inhibits photosynthesis. Brainstorm with your group some positive applications for this allelotoxin

20. Uniform distribution of single species since growth of other species would be inhibited. The single species would also be distributed from each other in equal or clumped intervals

21. No competition as all the surrounding plants have been inhibited. They can maximize use of all the nutrients effectively from the soil.

22. The other plants would be inhibited and there would be a loss of bio-diversity around the plant. There would be a growth of a single species.

23. Evolution only occurs due to competition and scarse resources. Because of allelopathy there is no competition so it would be unlikely that the species would evolve over time.

24. This can be used to suppress the growth of unwanted plants like weeds etc.

The advatntage of allelopathy to a plant is that the plant does not have to endure competition for resources with other plant species in the habitat.

What is Allelopathy?

The term allelopathy refers to the situation in which a plant inhibits the growth of other plants in the habitat by the secretion of a chemical.

In such a habitat, there would be no other competing species and the population distribution will be uniform. The advatntage of allelopathy to a plant is that the plant does not have to endure competition for resources with othetr plant species in the habitat. The disadvantage of allelopathy is that biodiversity is lost in the habitat due to the dominance of a single species. Evolution may not occur among species that exhibit allelopathy because there is no competition for resources.

The inhibition of photosynthesis by sorghum plant can be applied in the prevention of the gowth of weeds.
