Question

Which of the following conditions is needed by almost all seeds to break dormancy?

Options

• Exposure to light

• Imbibition

• Abrasion of the seed coat

• Exposure to cold temperatures

Answer 1

Imbibition

Explanation:

Almost all seeds need imbibition, which is the absorption of water by the seed, to break dormancy and initiate the germination process. Water uptake softens the seed coat and activates metabolic processes necessary for growth. Some seeds may require additional conditions such as exposure to light or cold, but most seeds do not require them to break dormancy.
