All of the following chemicals cause seed dormancy, except
Solution:
Seed dormancy is a state where seeds fail to germinate even under favorable conditions. This dormancy can be induced or maintained by certain chemicals. Abscisic acid (ABA) is a well-known plant hormone that promotes dormancy, including seed dormancy, and inhibits germination. Phenolic acid and Para-ascorbic acid are also known to act as inhibitors of seed germination and can contribute to dormancy. In contrast, Gibberellic acid (GA) is a plant growth regulator that is known to break seed dormancy and promote germination. Therefore, Gibberellic acid is the chemical that does NOT cause seed dormancy.
