Question

The term allelopathy was coined by

• A. Holm
• B. Harper
• C. Molisch
• D. Arnon

Hint:

Think of the Austrian botanist who introduced this term in 1937.

Answer 1

The Correct Option is C

Allelopathy describes a plant's chemical effect, good or bad, on the growth of another plant nearby. The word itself has a specific origin that this question is testing.

1. Holm: Recognized for his extensive work on documenting world weeds, not for naming this term.
2. Harper: A plant ecologist known for work on plant population dynamics and competition, but not the source of this word.
3. Molisch: An Austrian botanist who coined the word allelopathy in 1937 to describe chemical interference between plants.
4. Arnon: Known for establishing the criteria of essential plant nutrients, unrelated to this term.

Since Molisch is the botanist on record for introducing this word in 1937, he is the correct answer.

Let's summarize:

• Allelopathy means one plant chemically affecting the growth of another plant.
• Hans Molisch introduced this term in 1937.

So the answer is Molisch, option 3.
