Question

Seed dormancy is associated with

• A. Hard seed coat
• B. Immature embryo
• C. Presence of germination inhibitors
• D. All of these

Answer 1

Answer: (D)

All of these

Seed dormancy is defined as a state in which seeds are prevented from germinating even under environmental conditions normally favourable for germination. There are a few main causes of seed dormancy, such as hard seed coat, which are impermeable to water and gases so restrict water uptake and oxygen exchange. The immature embryo that is seeded with small and undeveloped embryos do not germinate. Germination inhibitors that is Seeds contain some chemical plant growth regulators, which inhibit seed germination.

So, the correct option is, 'all of these'.
