Question

Which of the following chemicals can be applied to the seed to induce dormancy?

• A. Abscisic acids
• B. Gibberellic acids
• C. Cytokinin
• D. Kinetin

Answer 1

The correct option is A Abscisic acids

Seed dormancy is the state of lack of germination of seed under unfavourable conditions. This adaptation increases the chance of survival of the seedling. Chemicals like plant hormones help regulate the seed dormancy. Hormones like gibberellic acid, cytokinin, and kinetin help to break the dormancy of seed to initiate seed germination. However, hormones like abscisic acid help induce seed dormancy. This aids seeds to be able to withstand water loss and other factors unfavourable for seed germination.
