What is allelopathic effect?

Allelopathy is a common biological phenomenon by which one organism produces biochemicals that influence the growth, survival, development, and reproduction of other organisms. These biochemicals are known as allelochemicals and have beneficial or detrimental effects on target organisms.

Can trees release toxins?

Plants do not spew out the toxins into the environment; they only release them when the plant is injured, broken, touched or ingested. Volatile toxins can be released if a plant, containing toxic oils, is burned.

What is allelopathy and how does it occur?

Allelopathy is a biological phenomenon where one plant inhibits the growth of another. How? Through the release of allelochemicals, certain plants can greatly affect the growth of other plants either in a good or bad way by leaching, decomposition, etc. In essence, plant allelopathy is used as a means of survival in nature,…
