Question

Which of the following substances present in seed coats and cotyledons of seeds inhibit seed germination?

• A. Absicic acid
• B. Phenolic acid
• C. Ferulic acid
• D. All of the above

Answer 1

The correct option is D All of the above

• Germination is the process by which an organism grows from a seed or similar structure.
• The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.substances present in seed coats and cotyledons of seeds inhibit seed germination are Abscisic acid, Phenolic acid and Ferulic acid.
• Abscisic acid (ABA) reversibly arrests embryo development at radicle, growth initiation, inhibiting the water uptake which accompanies embryo growth.
• Hence, substances present in seed coats and cotyledons of seeds inhibit seed germination is Abscisic acid, Phenolic acid and Ferulic acid.
• So, the correct answer is 'All of the above'.
