What role does abscisic acid (ABA) play in seed development and maturation?
Options
- APromotes seed germination
- BInduces dormancy
- CStimulates root growth
- DEnhances flowering
Correct answer
B. Induces dormancy
Step-by-step solution
ABA stimulates the closure of stomata in the epidermis and increases the tolerance of plants to various kinds of stresses. Therefore, it is also called the stress hormone. ABA plays an important role in seed development, maturation and dormancy. By inducing dormancy, ABA helps seeds to withstand desiccation and other factors unfavourable for growth.
