Answer 1

The correct option is D All of the above

Seed dormancy can be defined as a condition in which seeds do not germinate.

It is the survival mechanism of seed as dormancy delays germination during unfavourable conditions.

The seeds enter into a state of dormancy due to various reasons. Some of them are:

1. The seed can enter into a state of dormancy if the embryo is immature.

2. Certain substances present in the seed coat prevent it from germination. These are called inhibitors.

3. The presence of hard seed coat prevents the seed from germination.
