Solution

Abscisic acid is also known as the stress hormone. It is because this acid induces various types of responses in plants against some stress conditions. Stress conditions include the closure of stomata during drought conditions, seed dormancy. It also ensures seed germination during favourable conditions and withstands desiccation.
